Read the following this morning, and liked it so much I decided to look for more. :)
For those not familiar with Farley Mowat, he was a crusty but popular Canadian icon (he hated that label but I'm gonna use it anyway) who authored forty-one books (which I'm embarrassed to say I haven't read any of yet), a noted environmentalist, a lover of nature (not all environmentalists necessarily love nature I've come to suspect), an important critic, and an influential figure.
And while he wasn't vegan (although I like to think he eventually would have become so), he nonetheless was a champion for other sentient beings and certainly recognized the destructiveness of the human species.
“It is to this new-found resolution to reassert our indivisibility with life, to recognize the obligations incumbent upon us as the most powerful and deadly species ever to exist, and to begin making amends for the havoc we have wrought, that my own hopes for a revival and continuance of life on earth now turn. If we persevere in this new way we may succeed in making man humane ... at last.”
