Like the Hindu faith, the Jewish faith is among the oldest continuous religions, born when people lived in nature, not in cities. Some of Judaism’s major holidays are based on ancient harvest festivals: wheat and barley in late spring, olives and grapes in autumn. We even have a New Year of the Trees, one of my favorite holidays. The blossoming of the almond tree, the first tree to bloom in Israel, signals its start. I planted an almond tree in my garden here in San Jose just to wonder at its beauty in bloom.
Over millennia, life continued, following Earth’s natural rhythms: rain in its season, dry warmth in its. People, like the wildlife around them, lived within the boundaries of Earth’s cycles. In the past century, however, human technology began to overtake nature. Our dominance of nature became pronounced in the past 50 years. As we caused the natural world to become out of sync and detrimental to life, environmental organizations, both secular and religious, grew to counter the problems. In the past few years, one environmental crisis—more threatening than any other—loomed as existential: climate change.
The Jewish community had no organization devoted solely to solving the climate-change crisis. Two years ago, Rabbi Jennie Rosenn, who worked for 20-plus years in social justice organizations, realized that many of the issues she worked on would be ameliorated by tackling climate change. So she started Dayenu: a Jewish Call for Climate Action.
