Aytzim: Ecological Judaism — Green Zionist Alliance: The Grassroots Campaign for a Sustainable Israel

Aytzim (meaning "trees" in Hebrew) is a New York-based secular, progressive and pluralistic Jewish environmental organization that is a U.S.-registered 501(c)(3) tax-deductible nonprofit charity, incorporated as the Green Zionist Alliance. Aytzim has three projects: (1) Green Zionist Alliance: The Grassroots Campaign for a Sustainable Israel. The Green Zionist Alliance works to protect and educate about the environment of Israel and the Middle East. (2) Jewcology: Home of the Jewish Environmental Movement. With more than 1000 blog posts, pedagogical materials, a job board, and an interactive map of Jewish-environmental initiatives, Jewcology.org is the largest online resource for information on Jewish environmentalism. (3) Shomrei Breishit: Rabbis and Cantors for the Earth. More than 100 Jewish clergy, including chief rabbis from around the world, have joined this environmental-advocacy group that Aytzim runs in partnership with GreenFaith.
