The oil still gushing out of the bottom of the ocean in the Gulf should make us all aware that we are all part of the problem. Choosing to use hand tools instead of machinery is one small way we can cut back on our consumption. In this post, I describe how I sharpened an old sickle and cut down my green manure crop of a rye-clover-vetch mix (mostly rye) by hand. Let me tell you, it made me feel pretty darn powerful! Try it. You'll like it. And so will our environment.
