One thing is all things. To resolve one matter, one must resolve all matters. Changing one thing changes all things. Once I made the decision to sow rice in the fall, I found that I could also stop transplanting, and plowing, and applying chemical fertilizers, and preparing compost, and spraying pesticides.
I am really concerned about all of the chemicals. Global warming is another huge one, but the amount of chemicals being used in like laundry detergents and fertilizers is concerning.
