When I was a boy, there were few beavers around. This was true even in rural Oregon, the beaver state. Well now there are more beavers than you can shake a stick at.
Too many beavers, in fact, since they're undoing what people have done to tame nature and otherwise control water.
It's funny, we liked them for the fur, we love them as a symbol (see Oregon state flag at right, the only state flag with images on two sides, and look there's a lovely little beaver on the back!)
What'll we do with too many beavers? Start a bounty program to get rid of them? Or learn to live with them?
