About Us

“Think of a desert: It looks barren — but a little bit of water completely changes everything. That's a nice metaphor for what we are trying to do — be that little bit of change, the one drop of water that makes all the difference.”

— Rabbi Michael Cohen, co-founder of Aytzim: Ecological Judaism

Israeli Nature Poll

What is your favorite natural area of Israel?


"One may not dig a cistern close to the cistern of another, nor a trench, nor a vault, nor a water channel, nor a washer-man's pool, unless it is three tefahim distant from the wall of the other, and he must plaster it with lime. One must place olive peat, dung, salt, lime and rocks three tefahim away from the wall of one's neighbor, and he must plaster it with lime. Seeds, the plough and urine must be three tefahim away from the wall."

- Mishnah Bava Batra 2:1
