Klinkenborg has written a beautiful treatise against the mainstream of industrial agriculture and in favor of nature.
"...nature's big idea is to try out life wherever and however it can be tried, which means everywhere and anyhow. The result — over time and at this instant — is diversity, complexity, particularity, and inventiveness to an extent our minds are almost unfitted to conceive."
He goes on to say that we really ought to be rethinking the way we do agriculture.
"A reasonable agriculture would do its best to emulate nature."
