the value of tikkun olam — the Jewish commitment to repairing the world.…
Today, part of repairing the world means ensuring that we can reduce our individual consumption to sustainable levels….
The energy consumed in food production could be reduced greatly if we switched to a non-industrial system. For example, farmers could replace petroleum-based fertilizers with manure, a natural, time-tested option.
In other words: Do tikun olam by switching to manure as a fertilizer.
It's not just Ms. Zoninsein. The well-regarded organization Tevel Betzedek includes, as part of its mission, "creating Israeli and Jewish leadership passionately involved in 'Tikkun Olam' (repairing the world) locally and globally". Toward that mission, they switch villages that "[u]se chemical pesticides and fertilizers that degrade the soil and poison the environment" to villages in which "[f]armers use organic farming methods preserving the environment and utilizing existing resources".
Again: Use manure as a fertilizer to do tikun olam.
Yet in the prayer "Alenu" we say that "l'saken olam", to do tikun olam, includes:
לְהַעֲבִיר גִּלּוּלִים מִן הָאָרֶץ / to remove manure from the earth
How do reconcile these seemingly contradictory sources?
