Kibbutz Sdeh Eliyahu in the Beit She'an Valley, one of the first religious Kibbutzim in Israel, has decided to become a pioneer once again. A resolution passed by a majority of the members last week stipulates that the commune will become an "ecological community." The change will be made gradually, with the first stage being implemented in its treatment of trash. All locally-produced waste will be recycled or otherwise treated in the Kibbutz, and will not be sent outside. The next stage will put a stop to all insecticidal and other spraying - first in the fields, then in private homes. Members of the kibbutz, which is known for its pioneering work in organic agriculture and biological disinfestation, say, "We're striving to reach harmony with nature."
