An Open Letter to Rabbis

Dear Rabbi, News of war and conflict are the order of the day, but something far worse looms over us. I am writing you because you have the potential to help avert a climate catastrophe and leave a sustainable world for future generations. There is a very strong consensus composed of almost all climate experts, all the major science academies, and over a thousand peer-reviewed articles in respected science journals that climate change poses an existential threat to humanity. Animal-based diets which seriously violate fundamental Jewish teachings, are the major contrib...

WhichCame First, the Chicken or the Egg? – A Purimspiel

eb Henna taught: “Which came first, the chicken or the egg?  Clearly, the chicken.  How do we know this?  We learn from the Book of Esther that when Mordecai asked Esther to go before King Ahashveros to plead for the Jewish people, she was ‘chicken,’ fearing for her life. Only when Mordecai ‘Egged’ her on, telling her that perhaps she was enabled to be queen for just this EGGcelent purpose, did she muster the courage and ‘scrambled’ to appear before the king.” Reb Roosta said, “Speaking of birds, I heard that a Heavenly voice once announced: ‘A ...

Purim and Veganism

The joyous festival of Purim shares many connections with veganism. According to the Talmud (Megilla 13a), Queen Esther, the heroine of the Purim story, refrained from eating meat while she lived in the palace of King Achashveriosh. She was thus able to avoid violating the kosher dietary laws while keeping her Jewish identity secret. During Purim it is a mitzvah to give mat’not evyonim (charity to poor people). In contrast to these acts of sharing and compassion, animal-based diets involve the feeding of about 70 percent of the grain in the United States and ...

Purim Lessons That Can Help Avert a Climate Catastrophe

  There is increasing evidence that the world is approaching a climate catastrophe. The hottest year in recorded history was 2024, breaking the record set just the year before. Amazingly, all 13 months from June 2023 to June 2024 broke monthly temperature records. All 25 years in the current century are among the 26 hottest years since temperature records have been kept worldwide. Because of the hotter temperatures, there has been a significant increase in the melting of glaciers and Polar ice caps, causing sea levels to rise rapidly. There has also been a ...

Chrismukah: Giving Thanks for Miracles!

  This article was co-edited by Prof. Dan Brook (Bio at end)   Christmas on December 25 and Chanukah on 25 Kislev periodically coincide and do so again in 2024 on Christmas Day, which is the first night of Chanukah. Some are calling it Chrismukah. Some are calling it another miracle! Hope springs eternal. Indeed, it’s always been an integral part of Jewish and American history, spirituality, and politics. Without hope, there wouldn’t be a Chanukah; without hope, there might not even be a Jewish community; without hope, there might not be America ...

    Can a Climate Catastrophe Be Prevented?

Humanity's most urgent issue is whether a climate catastrophe can be prevented. Alarming trends and recent extreme climate events suggest that the world is approaching a critical tipping point. In 2024, heat waves were so frequent and intense that by early November, the year was declared the hottest in recorded history—breaking the previous record set just one year earlier in 2023. Astoundingly, all 13 months from June 2023 to June 2024 set new monthly temperature records. Additionally, 25 of the 26 .hottest years on record have occurred in this century. This relentl...

Why Jews Should be Vegans or at Least Vegetarians

Veganism is the diet most consistent with fundamental Jewish teachings.  Judaism emphasizes pikuach nefesh, that Jews should carefully preserve our health and our lives. Of the 613 Jewish mitzvot (commandments), 610 can be overridden if it might help save a life. The only three exceptions are the prohibitions against murder, idolatry, and sexual immorality. However, many scientific studies have linked animal-based diets to an increased risk of heart disease, stroke, several types of cancer, and other life-threatening diseases. These findings are consistent with the ...

The Work Continues: Brief Aytzim Statement on the 2024 Election

6 Nov. 2024 / 5 Cheshvan 5785 For many who care about environmentalism and addressing climate change — and for many who fight White supremacy — the results of Tuesday’s election are exceptionally concerning. Among other promises, the president-elect — whose campaign rhetoric and first White House term were tainted by extensive anti-Semitism and other forms of racism — has vowed to gut environmental programs, reversing many federal-government policies that address climate change. Take some time to mourn what could have been had a different candidate won. Here ...

Review of Animal Welfare in World Religion

Joyce D’Silva’s book Animal Welfare in World Religion; Teaching and Practice points out an anomaly that is the main reason that the world is rapidly approaching a climate catastrophe and facing other environmental threats. While about 80 percent of the world’s people belong to a religion and these religions have strong teachings about compassion for animals, the vast majority of the people have animal-based diets that involve great cruelty to animals. Animal-based agriculture is the main cause of climate change for two very important reasons. Cows and ...

Sukkot, Simchat Torah, Shemini Atzeret, and Veganism

There are many connections between veganism and the Jewish festivals of Sukkot, Shemini Atzeret (the Eighth Day of Solemn Assembly), and Simchat Torah: 1. Sukkot commemorates the 40 years when the ancient Israelites lived in the wilderness in frail huts and were sustained by manna. According to Isaac Arama (1420-1494), author of Akedat Yitzchak, and others, the manna was God's attempt to reestablish a vegan diet for the Israelites. 2. On Simchat Torah, Jews complete the annual cycle of Torah readings and begin again, starting with the first chapter of Genesis, which ...

Earth Etude for Elul 29

This is Where it All Begins by Rabbi Judy Kummer ~Human beings have often pondered the question of which came first, the chicken or the egg. As a gardener, I think more about the cycle of pollination and the growth of seeds and plants and flowers, which lead to more pollination and ultimately to the growth of more seeds. I thought of this recently as I was watching a bumblebee drowse lazily among glorious flowers in a garden, pollinating the blooms and allowing for the creation of more seeds and flowers. In the musical Hamilton, they sing of “the room where ...
