This weekend begins the “Earth Week” starting with the March for Science and culminating next weekend with the People’s Climate March. Both will be held in Washington, DC, with satellite marches across the nation and around the globe. We are living in a perilous time: we’ve already exceed the greenhouse gas emissions goal of 350 ppm, each year tops the previous one as “the hottest on record” and efforts are underway to gut the Environmental Protection Agency. The effects of climate change, including drought, floods and increased temperatures wreak havoc on crops, threatening our food supplies. We can make a significant reduction in our climate emissions through our food choices (9% of all greenhouse gas emissions in the US come from agriculture). Torah teaches us that we are God’s partner in protecting creation, bal taschit (do not destroy/waste) is a central teaching, and our calendar follows the agricultural cycle. “The LORD God took the man and placed him in the garden of Eden, to till it and tend it” (Genesis 2:15). The following tips to reduce one’s carbon emissions through food choices can be easily be done at home, schools, and shuls (and details about Jewish involvement in the People’s Climate Shabbat/March and other resources).
It also includes the following. “When you besiege a city for many days to wage war against it to capture it, you shall not destroy its trees by wielding an ax against them, for you may eat from them, but you shall not cut them down.” (20:19)
This injunction to protect fruit trees is a foundation of bal tashchit (do not destroy) and “is the halakhic basis of an ethic of environmental responsibility,” writes Rabbi Jonathan Sacks. Chabad.org explains that bal tashchit, “underscores the Divine imperative for us to take matters concerning the preservation of our environment very seriously.”
