More than two dozen individuals whose work involves food security and climate change issues met on Feb. 9 for Tu b’Shevat Circle: Teachings from the Earth, an event spearheaded by Or Shalom Synagogue in partnership with Jewish Family Services, JQT Vancouver and UNIT/PITT Society for Art and Critical Awareness.

Those who gathered work or devote time to such organizations as Grandview Woodland Food Connection, Sustainabiliteens, Coquitlam Farmers Market and Extinction Rebellion. They came together to explore various topics, including how their Jewishness intersects with their work in secular organizations, envisioning a sustainable world and the Jewish community’s role in social justice.

“I noticed that so many of these organizations are spearheaded by young Jews and felt it important to create an opportunity for them to see one another and recognize this aspect of kinship in their work … and whether this commonality enhances the work, draws them into kinship or stimulates any collaboration,” said Or Shalom’s Rabbi Hannah Dresner.

Or Shalom brought on Carmel Tanaka to organize a gathering. Through meetings with young adults and stakeholder groups, Tanaka met a number of people whose careers relate to food security and social justice, but most weren’t working for Jewish organizations nor were they connected to one another within a Jewish context. She and Dresner agreed it was worth bringing them together to see what conversations would blossom.

Tanja Demajo, chief executive officer of Jewish Family Services, said JFS provided funding for the event because they believed in the value of the project.

“There are a lot of Jewish and young Jewish people who are interested in food security and questions of accessibility, which is very interesting from a perspective of … whether this work is modulated by [Jewish] values and how this translates to day-to-day practice,” she said. “At the end of the day, it didn’t really matter if the different participants were working in a Jewish or non-Jewish community.”

Some attendees revealed that, for them, being Jewish is secondary to their focus on environmental issues.

“The room was full of people who identify in varying degrees with their Jewishness and, for some, it’s an important aspect of their identity and, for others, it isn’t integral,” Tanaka said.

Dresner spoke to the indelible connection between environmental action and Judaism. “In my understanding of Judaism, saving our world is at the heart of what it means to have a Jewish spiritual life,” she said. “Creative energy, or the vitality of spirit, is always flowing toward us. It’s what I’d call the ‘world that’s always coming,’ or the ongoing nature of creation. We can encourage and aid this vitality, helping to direct it where most needed, or we can impede the flow. When we are selfish and impede creative flow, the result is a deprivation of generative spirit, spirit denied to corners of creation, and we see results like species blinking into extinction.”

The rabbi wants to spend more time with young Jews working in social justice. “The Judaism I believe in mandates their work as the highest mitzvah of our moment,” she said. “It’s a misconception born of the compartmentalized Judaism in which many of us were raised not to understand that attention to the environment is a Jewish priority.”

Aaron Robinson, chair of Grow Local Society Tri-Cities, a food security group that runs the Coquitlam Farmers Market, said his work for the organization won’t ever have a Jewish mandate, but his Judaism is tied into what he does. “Personally, I can never underestimate the role that Jewish values play in the way I see the world, especially when it comes to tikkun olam,” he said, adding, “I guess it’s become engrained in me, but it was nice to bring it back to the surface to see, wow, there is this Jewish connection to all this work that we’re doing.”

Robinson appreciated the opportunity to connect with other Jews working in similar fields and hopes the conversations will continue.

Some people discussed not feeling supported by the Jewish community to undertake the work they do within a Jewish context. Tanaka said she believes the Vancouver Jewish community hasn’t focused attention on these issues until recently, citing the 2019 climate march and protests as a galvanizing factor, and said it’s time for the local community “to support young Jewish adults who are doing this kind of work … because these are Jewish issues at the end of the day.”

Some at the event suggested funding for environmental advocacy was needed. Dresner said there was also a desire for bridge building. “They seem to be asking for an arm of organized Jewish community to create some occasional containers for their gathering, just to share within the hybrid of their niche or to explore potential collaborations,” she said. “Or Shalom will be looking at finding funding to continue holding this group and its outgrowth in a loose, nurturing embrace.”

Demajo said the JFS food security program has already benefited from the event. “Being exposed to more city-wide programs and initiatives and being exposed to all different voices gives a different perspective to JFS,” she said, “because it opens up new ideas.”

History and future combine

Two Jewish theatre artist-creators, Ariel Martz-Oberlander and Ilana Zackon, teamed up this summer to create an immersive piece based on the Jewish partisan movement, as part of Radix Theatre’s futuristic play Time Machine, set on a boat, the Pride of Vancouver.

The show took place on the yacht over a five-hour journey up Indian Arm (traditionally known as səl̓ilw̓ət) and featured both local emerging and established artists presenting new work of various genres, such as theatre, spoken word poetry, sound installation and more. The artists were asked to create a piece inspired by what Vancouver will look like in the year 2050. Some darker, others playful, the works were all grounded in a strong sense of the artists’ identities.

Martz-Oberlander and Zackon wanted to bring their ancestral roots into their piece. The pair created an immersive show in which they played two rebels helping smuggle climate refugees to safety. The 10-minute piece, which ran on a loop for an hour-and-a-half of the boat ride, took place in the boat’s basement bathroom, which acted as a safehouse. Five to seven audience members at a time were summoned by Zackon, dressed as a soldier, down into the dimly lit bathroom, where they were greeted by a similarly dressed Martz-Oberlander; “Zog Nit Keynmol” (“The Partisan Song”) played in the background.

The invited audience soon discovers they are now refugees who have just escaped fires in California. The soldiers, members of a new wave of partisans called PAP, explain that the refugees are being brought to another safehouse and prepared to enter the new world. The soldiers explain that their resistance cohort has based their movement on the survival lessons of their ancestors, partisan fighters in the forests of occupied Europe. The audience members are given new names, briefed on the types of skills, such as hunting moose, that they will need to survive in their new lives and, eventually, led into a discussion on identity.

“What’s better: start over or remember where you’re coming from?” Martz-Oberlander’s character asks. The two soldiers bicker over their differing views and invite the audience to contribute. After the group has spoken, the soldiers receive word that it is safe to move the refugees. Before leaving, audience members are given the option of writing down “one thing about their identity they don’t want to lose in the new world” on a sticky note. The notes lined the stairwell and, as the loop continued, more and more words were added, creating a tapestry of human identity. The notes lined the bathroom walls for the remainder of the boat ride, and included such items as “curiosity and kindness,” “time to think,” “my favourite berry picking spot,” “my knowledge of languages” and “the giggles of my daughter,” among many others.

A number of the boat passengers who attended the piece were Jewish and shared how they connected with their ancestors through remembering their stories. Many non-Jews had never heard of the partisan movement and the two artists felt the work they did helped educate people on an important part of history.

Zackon and Martz-Oberlander also received, from the Jewish Museum and Archives of British Columbia, transcripts of interviews with Jewish refugees coming to Canada during the 1930s and 1940s. These testimonials were hidden around the safehouse and incorporated into the performance. The two artists hope to receive the opportunity to continue developing and expanding this work and to incorporate more of their own personal family stories about immigration to Canada.

Need earth-friendly policies

We are now well into the Hebrew month of Elul, which provides an incentive for heightened introspection, a chance to practise teshuvah, changes in our lives, before the Days of Awe, the Days of Judgment, the High Holidays of Rosh Hashanah and Yom Kippur. The shofar is blown every morning (except on Shabbat) in synagogues during the month of Elul to awaken us from slumber, to remind us to consider where we are in our lives and to urge us to consider positive changes.

How should we respond to Elul today? How should we respond when we hear reports almost daily of severe, often record-breaking, heat waves, droughts, wildfires, floods and storms; when July 2019 was the hottest year since temperature records were kept in 1880; when 18 years in this century are among the 19 hottest years and 2014, 2015 and 2016 successively broke temperature records; when polar ice caps and glaciers are melting far faster than projections of climate experts; when climate scientists are warning that we could be close to an irreversible tipping point when climate change could spiral out of control with disastrous consequences, unless major changes are soon made; when we appear to also be on the brink of major food, water and energy scarcities; and when, despite all of the above, so many people are in denial, and almost all of us seem to be, in effect, rearranging the deck chairs on the Titanic as we approach a giant iceberg?

Israel is especially threatened by climate change since, among other dangers, a rising Mediterranean Sea could inundate the coastal plain, which contains much of Israel’s population and infrastructure; and the hotter, drier Middle East projected by climate experts makes terrorism and war more likely, according to military experts.

It is well known that one is not to shout fire in a crowded theatre – except if there actually is a fire. The many examples of severe climate change indicate that the world is on fire today. Therefore, we should make it a priority to do all that we can to awaken the world to the dangers and the urgency of doing everything possible to shift our imperiled planet onto a sustainable path.

We should urge that tikkun olam (the repair of the world) be a central focus in all aspects of Jewish life today. We should contact rabbis, Jewish educators and other Jewish leaders and ask that they increase awareness of the threats and how Jewish teachings can be applied to avert impending disasters. We should write letters to editors, call talk shows, question politicians and, in every other way possible, stress that we can’t continue the policies that have been so disastrous.

As president emeritus of Jewish Veg, formerly Jewish Vegetarians of North America, I want to stress that shifting toward a vegan diet is something that everyone can do right away. It would significantly reduce greenhouse gas emissions and it would be consistent with Jewish teachings on preserving human health, treating animals with compassion, protecting the environment, conserving natural resources, and helping hungry people.

The afternoon service for Yom Kippur includes the book of Jonah, who was sent by God to Nineveh to urge the people to repent and change their evil ways to avoid their destruction. Today, the whole world is Nineveh, in danger of annihilation and in need of repentance and redemption, and each one of us must be a Jonah, with a mission to warn the world that it must turn from greed, injustice and idolatry, so that we can avoid a global catastrophe.

Climate crisis a top priority

“It’s going to be our future, so it’s up to us to take it into our own hands and show that, even if we can’t vote, we can still make a difference in our communities and the world,” Malka Martz-Oberlander told the Jewish Independent when she and fellow activist and friend Rebecca Hamilton met with the paper to discuss recent – and future – efforts to draw awareness to the climate crisis.

The two high school students are part of the group Sustainabiliteens, which was inspired by Swedish climate activist Greta Thunberg. Last year, Thunberg started monthly school strikes, stating that preparing for a future that won’t have a livable climate was pointless. The strikes, called “Fridays for Future,” have spread to at least 270 countries, including Canada.

Inspired by Thunberg, strike action took place at Vancouver City Hall on Jan. 16, the day that Vancouver city council unanimously passed a motion put forward by Councilor Christine Boyle (OneCity) to declare a climate emergency. Similar motions have been adopted in other cities, including London, Los Angeles and Oakland, but Vancouver is the first in Canada to do so.

“Climate change is already impacting the people of Vancouver and will continue to. We need to respond to this crisis urgently and compassionately with a path towards a more equitable society,” said Boyle in a release. “Adequately addressing the climate emergency won’t be easy, but we are a smart city, capable of doing difficult things.”

Hamilton was an organizer of the strike at City Hall, and the groups Force of Nature and Extinction Rebellion Vancouver also supported the action. There was a previous school walkout and strike for the climate on Dec. 7, said Martz-Oberlander. She and Hamilton are among a growing number of Metro Vancouver teens coming together in what Martz-Oberlander describes as a “shared passion for climate justice.”

“With some of my friends, it’s just doom and gloom,” said Martz-Oberlander. “There’s this sense of this is all going to happen and no one can do anything, so why do anything? It’s out of our hands, we’re just kids…. But there’s also a lot of people that I know who are hopeful and see the bigger picture.”

“When I ask kids about the climate crisis,” said Hamilton, “they say that they think it’s a real problem and they’re scared. But the world around us doesn’t recognize what’s happening with the same sense of urgency that we feel. We are living in a confusing and weird time. On the one hand, we understand the science, we’re being told the scientific facts that we’re in a crisis. We’re being told these very conflicting messages, and there’s this dissonance. So what am I supposed to believe? The world is just going as normal, but why are you telling me then that we’re in this crisis and everything needs to change? I think that’s really frustrating. Me, personally, every day I’m frustrated by that.”

Both Martz-Oberlander and Hamilton grew up in the Vancouver Jewish community and say their Jewish values inform their activism. Martz-Oberlander’s family has been involved with Congregation Or Shalom since before she was born, and Hamilton grew up going to Temple Sholom.

“In the Torah, it talks about needing to pass down this world better than we got it,” said Martz-Oberlander. “That’s the concept of l’dor v’dor, ‘from generation to generation.’ The Jewish teaching that really influenced me is the sense of responsibility towards future generations.”

“Camp Miriam was most important to me in cultivating my Jewish identity,” said Hamilton. “I think it played a huge role in what I’m doing and why I care about it. The focus on youth agency, being told we could create change. It’s tikkun olam – environmentalism and climate justice is the most important way to try and help other people and create a more just world.”

Both teens avoid the word “climate change,” preferring instead to talk of the “climate crisis” or “climate emergency” and the need for “climate justice.”

“Climate change doesn’t sound urgent enough,” said Martz-Oberlander. “It’s an emergency.”

“I prefer climate emergency or climate crisis,” said Hamilton, who cites Jewish writer and activist Naomi Klein as an important influence on her thinking. “It’s not about preventing this catastrophe but about healing the foundation of our world. The climate crisis is a manifestation of these unjust worldly systems which exploit nature, animals and people, so fixing that manifestation will also mean fixing those systems.”

Hamilton and Martz-Oberlander were inspired to join the climate-strike movement after it came to Canada with a strike in Sudbury, Ont., led by 11-year-old Sofia Mather.

“I feel like I have been concerned about climate change my whole life,” said Hamilton, “but I began to want to do something when I realized that nothing else really matters if we live on a dead planet.”

Hamilton and Martz-Oberlander are currently preparing for a Canada-wide school strike on May 3, and have a local action planned for Feb. 15.

Is God’s very good world OK?

(photo from jpl.nasa.gov)

Rosh Hashanah commemorates God’s creation of the world. During the 10 days from Rosh Hashanah to Yom Kippur, we evaluate our deeds and do teshuvah (repentance) for cases where we have missed the mark. And, during Sukkot, we leave our houses and live in temporary shelters to commemorate our ancestors’ journey in the wilderness. Hence, these weeks provide an excellent time to consider the state of the planet’s environment and what we might do to make sure that the world is on a sustainable path.

When God created the world, He was able to say, “It is tov meod,” very good. (Genesis 1:31) Everything was in harmony as God had planned, the waters were clean, and the air was pure. But what must God think about the world today?

What must God think when so many species of plants and animals He created are becoming extinct at such an alarming rate in tropical rain forests and other threatened habitats; when the abundant fertile soil He provided is being depleted and eroded; when the climatic conditions He designed to meet our needs are threatened by climate change?

An ancient rabbinic teaching is all-too-relevant today: “In the hour when the Holy one, blessed be He, created the first human being [Adam], He took him and let him pass before all the trees of the Garden of Eden and said to him: ‘See my works, how fine and excellent they are! All that I have created, for you have I created them. Think upon this and do not corrupt and destroy My world. For, if you destroy it, there is no one to set it right after you.’” (Midrash Ecclesiastes Rabbah 7:28)

Today’s environmental threats bring to mind the biblical 10 plagues. When we consider the threats to our land, water and air from pesticides and other chemical pollutants, resource scarcities, acid rain, deforestation, desertification, threats to our climate, etc., we can easily enumerate more than 10 modern “plagues.” The Egyptians were subjected to one plague at a time, while our modern plagues threaten us simultaneously. And the Israelites in Goshen were spared most of the biblical plagues, while everyone on earth is imperiled by the modern plagues.

Instead of an ancient pharaoh’s heart being hardened, our hearts today seem to have been hardened by the greed, materialism and waste that are at the root of current environmental threats. While God provided the biblical plagues to free the Israelites, today we must apply God’s teachings in order to save ourselves and our planet.

There seem to be almost daily reports about record heat waves, severe droughts and wildfires, the melting of glaciers and polar ice caps, an increase in the number and severity of hurricanes and other storms, and other effects of climate change. All of the above, and much more, is related to a temperature increase in the past century of a little more than one degree Celsius, so it is frightening that climate experts project a temperature increase of three to six degrees Celsius in the next 100 years. Some leading climate experts have stated that global warming may reach a tipping point and spin out of control within a decade, with disastrous consequences, unless major changes soon occur.

All countries, including Israel, are affected by climate change. Israel is already suffering from one of the worst droughts in its history, with below average rainfall in each of the past five years, and the Kinneret, a major water source, at dangerously low levels.

Israeli climate experts are concerned that, with additional climate threats, there will be a rise in temperature causing many severe heat waves; a significant increase in the Mediterranean Sea level, which would threaten the narrow coastal strip of land that contains most of Israel’s population and infrastructure; and a significant decrease in rainfall, estimated at 20%-30%, which would disrupt agricultural production and worsen the chronic water scarcity problem in Israel and the region. Making matters worse, much of that rainfall would come in severe storms that would cause major flooding.

Fortunately, there are many Jewish teachings that can be applied to shift the earth to a sustainable path. Briefly, these include our mandate to be shomrei adama (guardians of the earth), based on the admonition that we should “work the earth and guard it” (Genesis 2:15); the prohibition of bal tashchit, that we should not waste or unnecessarily destroy anything of value (Deuteronomy 20:19-20); the teaching that, “The earth is the Lord’s and the fullness thereof” (Psalms 24:1), and that the assigned role of the Jewish people is to enhance the world as “partners of God in the work of creation” (Shabbat 10a); and the ecological lessons related to the Shabbat, sabbatical and jubilee cycles.

As coworkers with God, charged with the task of being a light unto the nations and accomplishing tikkun olam (repair of the earth), it is essential that Jews take an active role in applying our eternal, sacred values in struggles to reduce climate change, pollution and the waste of natural resources. Jews must work with others for significant changes in society’s economic and production systems, values and lifestyles. The fate of humanity and God’s precious earth are at stake and, if we fail to act properly and in time, there may be “no one after us to set it right.”

The tough choices

The value of ahavat ha’beriot, the love of God’s creations, is open to broad interpretation. The animal world, the environment, as well as other people, can all fall under this crucial tenet of Judaism.

Like positive values and most good things, of course, this is easier in theory than in practice. We all want a clean environment and a better world, but we also want the convenience of automobiles, abundant and varied food, and the panorama of disposable consumer goods that we associate with the “good life.”

Awareness is, on the one hand, the most important factor in social change. On the other hand, it can overwhelm us to learn the full scope of our impacts on the world. Leave aside the huge looming catastrophe of climate change and consider for a moment the impact of a single, almost universal item of clothing: the cotton T-shirt.

Some bumper sticker wisdom urges us to “live simply, that others may simply live.” We do not always think of our wardrobe when considering our carbon footprint. Yet, after housing, food and transportation, for many people, clothing is one of the largest expenditures. Since voting with our wallets is one important way of making change, it is worth considering the impacts of our wardrobe choices. And what we wear on our backs says more about us than merely our fashion sense. It speaks (whether we know it or not) about our views on the environment and matters like child labour and fair wages.

To this end, one might think that a basic T-shirt would be a good choice. Yet it can take up to 2,700 litres of water to produce the cotton required for this simple garment, according to the World Wildlife Federation. Caring for the T-shirt over its lifespan takes further resources: each load of laundry takes more than 150 litres of water. Throwing it in the dryer (with a full load) consumes even more energy resources than the washing machine – about five times as much. Hanging it instead on a clothesline would reduce the shirt’s carbon footprint by one-third, but who remembers those? (Walk down a back lane in Vancouver a generation ago, and clotheslines snaked across almost every yard.) That few of us would be prepared to make this comparatively small shift indicates the glacial – to use an ironic term in the context – pace of human change in a time of rapid change in the environment.

Our food choices are even heavier with impacts. Researchers at institutions including the Weizmann Institute of Science calculated the use of land area, water and nitrogen fertilizer in animal food production. Potatoes, wheat and rice require half to one-sixth of the resources needed to produce pork, chicken, dairy and eggs in a calorie-for-calorie comparison. (Beef takes as much as five times the resources as chicken.)

Livestock for food are estimated to create about 20% of greenhouse gas emissions while using vast amounts of agricultural and water resources. Reducing or giving up meat consumption results in a huge reduction in resources. Producing a kilogram of protein from beef requires about 18 times more land, 10 times more water, nine times more fuel, 12 times more fertilizer and 10 times more pesticide than producing a kilogram of protein from kidney beans. But, again, many people love a steak or roast chicken and giving up these pleasures is not on the agenda.

This is not to instil hopelessness that even our simplest choices are leading to environmental disaster. Rather, it is to be aware of the power of small changes to have significant results.

We can extrapolate the outsized impacts of larger choices. When faced with the realities of carbon fuels on our environment (and health), most of us will not choose to sell our cars. But we might use them more judiciously. Or buy a more fuel-efficient vehicle. And, when it comes to making big political decisions that impact our environment and health, we might consider that, on balance, we should be moving toward investing in alternatives to fossil fuels, not pouring public or private billions into perpetuating deleterious and nonrenewable resources. We may not go cold turkey on gasoline and oil overnight, but our discrete choices should be leading incrementally in the right direction, not the wrong one.

Climate change heats up Israel

A new study says that, by 2100, climate changes will extend the summer season in the eastern Mediterranean – an area that covers Israel, Egypt, Jordan, Syria, Lebanon and southern Turkey – by two full months. Winter, the rainy season, will shorten from four to two months.

The study, published in the International Journal of Climatology, was overseen by Prof. Pinhas Alpert and conducted by Assaf Hochman, Tzvi Harpaz and Prof. Hadas Saaroni, all of Tel Aviv University’s School of Geosciences.

“Pending no significant change in current human behaviour in the region, the summer is expected to extend by 25% by the middle of the century (2046-2065) and by 49% until its end (2081-2100),” Hochman said. “The combination of a shorter rainy season and a longer dry season may cause a major water problem in Israel and neighbouring countries.”

Other serious potential consequences include increased risk of brushfires, worsening pollution and altered timing and intensity of seasonal illnesses and health hazards.

“One of the main causes of these changes is the growing concentration of greenhouse gases emitted into the atmosphere as a result of human activity,” said Hochman.

The research team is currently exploring the possibility of establishing a multidisciplinary regional centre for climate adaptation.

Climate a Jewish issue

The World Health Organization has labeled climate change “the greatest threat to global health of the 21st century.” As a physician, it is difficult to ignore such a dramatic statement.

Climate change is real. The sea levels are rising, temperatures are increasing, more violent storms are becoming the norm. As Canadians, we are seeing consequences of climate change even more than other countries. Last year, Fort McMurray in Alberta was almost destroyed by a massive forest fire. This year was the worst year in British Columbia’s history for forest fire damage. (While climate change is not the sole cause of these events, it is known to be a contributing factor.)

Our glaciers are shrinking, as anybody who has visited the Athabasca Glacier in the Rockies can confirm. Temperatures in the Yukon and Northwest Territories are rising faster than in most other parts of the world. Traditional indigenous life in the north is being made much more difficult by the shortening of winter and the melting of the permafrost.

Climate change is also a Jewish issue. When the environment is changing so dramatically that human lives and well-being are at stake, Jewish values tell us that we must take action.

Pikuach nefesh (the saving of a life) is a fundamental Jewish principle. Climate change is believed to share some responsibility for present-day wars and loss of life, including the conflict in Syria. The World Health Organization predicts that 250,000 people will die each year between 2030 and 2050 due to the effects of climate change. Is it not incumbent upon us as Jews to try to mitigate these effects in line with the pikuach nefesh principle?

Climate change is a complex issue. Many people find it too complicated and too overwhelming, such that they are paralyzed into inaction. So what we can do about it?

In line with Jewish practice, the first response should be educating ourselves about the issues. There are many articles and books about the subject. One of the most compelling authors for me is Bill McKibben. He has written a book called Eaarth (Henry Holt and Company, 2010) in which he describes how the earth is changing, such that it is becoming a new and unfamiliar place.

Fossil fuels are the main culprits. Weaning ourselves off coal, oil and natural gas is paramount. Substituting sources of renewable energy such as solar, wind, tidal and geothermal is crucial.

On a society level, we can try to prevent further construction of oil and gas pipelines, and further development of the LNG (liquified natural gas) industry in northeast British Columbia. We can elect members of the Legislative Assembly and of Parliament who share our concerns.

On a personal level, we can drive less, fly less, use hybrid or electric vehicles, and support public transportation. We can eat less meat, as the cattle industry is a major contributor to increased greenhouse gases. We can consume less, recycle more and compost more.

Everybody can do something to help mitigate the effects of climate change. Doing nothing is no longer an option.

I take inspiration from the talmudic Choni, otherwise known as the Circle-maker.

One day, Choni was walking on the road and saw a man planting a carob tree. Choni asked the man, “How long will it take for this tree to bear fruit?”

The man replied, “Seventy years.”

Choni then asked the man, “And do you think you will live another 70 years and eat the fruit of this tree?”

The man answered, “Perhaps not. However, when I was born into this world, I found many carob trees planted by my father and grandfather. Just as they planted trees for me, I am planting trees for my children and grandchildren so they will be able to eat the fruit of these trees.”

This week, as we are sitting in the sukkah, let us contemplate the fragility of our planet, and strive to make the earth a more secure place for our children and grandchildren.

How to slow climate change

President Donald Trump has received well-deserved condemnation from, among others, leaders of many nations, many governors, mayors, environmentalists, corporate chief executive officers and Jewish and other religious organizations for withdrawing the United States from the 2015 Paris climate change pact that was agreed to by all the 195 nations that attended, including Israel, Canada and the United States. How should Jews respond to the U.S. withdrawal?

First, Jews should become very familiar with the issues involved. Ten important climate-related factors are:

Science academies worldwide, 97% of climate scientists and 99.9% of peer-reviewed papers on the issue in respected scientific journals argue that climate change is real, is largely caused by human activities and poses great threats to humanity. All 195 nations at the December 2015 Paris climate change conference agreed that immediate steps must be taken to combat climate change.
Every decade since the 1970s has been warmer than the previous decade and all of the 17 warmest years since temperature records were first kept in 1880 have been since 1998. The year 2016 was the warmest globally since 1880, breaking the record held before by 2015 and previously by 2014, meaning we now have had three consecutive years of record temperatures.
Polar icecaps and glaciers worldwide have been melting rapidly, faster than scientific projections. This has caused an increase of elevation in oceans worldwide, with the potential for major flooding.
There has been an increase in the number and severity of droughts, wildfires, storms and floods.
California has been subjected to so many severe climate events (heat waves, droughts, wildfires and mudslides when heavy rains occur) recently that its governor, Jerry Brown, stated, “Humanity is on a collision course with nature.” California serves as an example of how climate change can wreak havoc.
Many climates experts believe that we are close to a tipping point due to feedback loops, when climate change will spiral out of control, with disastrous consequences, unless major positive changes soon occur.
While many climate scientists think that 350 parts per million (ppm) of atmospheric CO₂ is a threshold value for climate stability, the world reached 400 ppm in 2014 and the amount is increasing by two to three parts per million per year.
While climate scientists hope that temperature increases can be limited to two degrees Celsius (3.6 degrees Fahrenheit), largely because that is the best that can be hoped for with current trends and momentum, the world is now on track for an average increase of four to six degrees Celsius, which would result in great human suffering and significant threats to human civilization.
The Pentagon and other military groups think that climate change will increase the potential for instability, terrorism and war by reducing access to food and clean water and by causing tens of millions of refugees fleeing from droughts, wildfire, floods, storms and other effects of climate change.
The group ConservAmerica, formerly known as Republicans for Environmental Protection, is very concerned about climate change threats. They are working to end the denial about climate threats by the vast majority of Republicans, but so far with very limited success.

Second, Jews should consider Judaism’s powerful teachings that can be applied to environmental sustainability. These include:

“In the hour when the Holy One, Blessed be He, created the first man, he took him and let him pass before all the trees in the Garden of Eden and said to him: ‘See my works, how fine and excellent they are. Now, all that I created, I created for your benefit. Think upon this and do not corrupt or destroy my world. For, if you destroy it, there is no one to restore it after you.” (Midrash: Ecclesiastes Rabbah 7:28)
Genesis 2:15 indicates that the human role is to work the land but also to guard and preserve it. Jews are mandated to be shomrei ha’adama, guardians of the earth, co-workers with God in working for tikkun olam, healing and repairing the world.
Judaism teaches: “Who is the wise person? The one who considers the future consequences of his or her actions.”
The Jewish sages expand Deuteronomy 20:19-20, prohibiting the destruction of fruit trees in wartime to build battery rams to overcome an enemy fortification, to make a general prohibition against unnecessarily destroying anything of value.

Jews should be on the forefront of efforts to help avert a climate catastrophe. We should try to significantly reduce our individual carbon footprints by recycling, using efficient light bulbs and other items, eating less meat, reducing our use of automobiles by walking, biking, sharing rides and using mass transit, when appropriate, and in other ways. We should support efforts to increase efficiencies of automobiles and other items, shift to renewable sources of energy and make societal steps that reduce greenhouse emissions.

We should try to arrange programs on climate change at synagogues, Jewish centres and other Jewish venues, write letters to editors, speak to family members, friends, neighbours and co-workers, and take other steps to increase awareness of the seriousness of climate threats and how applying Jewish values can help reduce them. We should do everything possible to reduce climate change and to help shift our imperiled planet onto a sustainable path.

How trees adapt to conditions

While studying trees during his postdoctoral fellowship, Dr. Tamir Klein made such a startling discovery that his research supervisor at the University of Basel at first declared that it must have been a mistake. In the forest, trees are known to compete for resources such as light and nutrients, but Klein found that the same trees also engage in sharing: he showed that carbon molecules taken up by the canopies of mature spruce trees were passed through the soil in large quantities to neighbouring beech, larch and pine. As he reported in Science in 2016, the carbon was being transferred via “underground highways” formed by overlapping networks of root fungi.

“Neighbouring trees interact with one another in complex ways,” said Klein. “Of course, there is a great deal of competition among them, but they also form communities, sorts of ‘guilds,’ within which individual trees share valuable resources. In fact, trees belonging to a ‘guild’ usually do much better than those that don’t.”

In his new lab in the Weizmann Institute’s plant and environmental sciences department, Klein follows up on these findings to investigate tree ecophysiology: how the tree functions in its ecosystem.

“Studies on ‘underground’ tree collaboration may reveal which tree species get along well, and this may help determine which trees should be planted next to one another,” he said. “Our studies have additional relevance to forestry and agriculture because we elaborate on the mechanisms of growth and drought resistance of different tree species.”

Only five percent of Israel’s land is covered by forest, but the country nonetheless offers unique advantages for forest research: its hot, dry climate provides an opportunity for investigating how trees adapt to drought and stress. Many trees common to Israel are already resistant to drought; understanding the mechanisms that allow them to live with little rain may help develop varieties of lemons, almonds, olives and other tree crops that can grow in even drier areas.

Projects in Klein’s lab aim to clarify how trees manage their water and carbon budgets – both separately and as a forest community. In one study, the team focuses on emboli: tiny air bubbles that form inside the tree’s water channels during drought. When drought persists, the emboli can kill a tree, much like blood vessel clots that can cause a fatal heart attack in a human being. After injecting fluids into tree branches at different pressures, Klein and his students analyze the emboli in the minutest detail, using micro-computed tomography.

In Weizmann’s greenhouses, Klein’s team members experiment with seedlings of pine, cypress, carob and other trees commonly found in Israel. The researchers make use of advanced technologies, including nuclear magnetic resonance imaging, to study hydraulic conductivity in trees and a special lamp-equipped belowground camera to study the growth of tree roots in the soil.

When conducting field studies on their research plot near Beit Shemesh, Klein and his students hug trees – not to have a spiritual experience, but to follow a tree’s growth by encircling the trunk with a measuring tape. In parallel, they apply laser isotope analysis and analytical chemistry techniques to trace carbon metabolism in individual trees, and they investigate carbon transfer among trees via different types of fungal “highways.” The scientists also employ thermal imaging, which enables remote temperature measurements, to study the rate of evaporation in the foliage.

These studies will help predict how future climate changes, including global warming and the rise in greenhouse gases, may affect forests. In one set of experiments, for example, Klein will double the concentration of CO₂ to mimic the atmospheric conditions that may emerge on earth as a result of pollution. Klein hasn’t owned a car in 10 years, so as not to contribute to CO₂ emissions, but he warns against jumping to conclusions when it comes to the impact of increased CO₂ on tree biology. “Higher CO₂ concentrations don’t help trees grow faster – contrary to the hopes of industrialists – but, surprisingly, recent research suggests they might render the trees more resistant to drought-induced stress. This doesn’t mean it’s OK to carry on with CO₂ pollution, but it does mean that we need to deepen our understanding of its effects on trees in general and on agricultural tree crops in particular.”
