Listened on Dsound this week. Choose biological. and the mystical (photosynthesis) haha I like to try and apply to my suburban existence. Clover in the yard. Manure as fertilizer. Non-chemical cleaners and lubricants or even fuels. Gray water used to water plants and yard. Goats are used a lot around here to mow steep hills or ditches that can't be mowed with machines. This is an interesting biological option not just a one-for-one swap but I greener AND better solution. I enjoyed the discussion at the end about using non-renewable resources to create renewable environment. And the ethical implications.
