Anyone thinking we can manage nature better than beavers has lost the plot. Beavers have been doing the same thing for as long as we know and never threatened nature, we've only had a real impact on nature for about 250 years and it's a mess already. And then there are a bunch of anglers, who put more hatchery fish in the rivers and lakes to have a good time and say beavers don't fit in the picture. Their distorted view of nature has become completely anthropocentric and denies the fact it were animals like beavers that created and preserved "their" nature. Humans can't even do that, but they are very good at pretending. Some even have strong opinions on beavers without ever having seen one at work in the real world. How could they? They have been wiped out of their manicured nature for centuries, like many other annoying animals. If it doesn't fit men's purpose it has to go and never come back. We have enough pictures and video footage to teach our children what's not there anymore. Provided they don't want to bring them back, otherwise smarter men will tell them why they can't do that. Human pragmatism rules the world and nature too. And we still call it paradise.
