Sustainability. Clean Water. Energy Conservation. Biodiversity. The Jewish values of taking care of the earth. Bal Tashchit. The commandment of Bal Tashchit—do not destroy or waste—has long been considered central to a Jewish environmental ethic. What is the basis for the commandment? We will explore how the Jewish tradition widely forbids wasteful acts, how wasting contributes to degradation of the planet, and how not wasting can help us improve our lives both physically and spiritually.
