Environmentalists here are tend to cause more trouble than good.
I can cite some good examples here in California:
The first case, revolves around the Spotted Owl. The Environmentalists insisted that logging in what is called "old growth" forests (old growth is pristine, unlogged tracts of woodland) was harming the Spotted Owl populations, causing an alarming decline in the species. They forced the courts to press an injunction against the logging companies, who owned the land that the timber stood on. As a result, the timber industry in Northern California started to collapse, jobs were lost, communities went broke, people moved away. And yet, the Spotted Owl population continued to decline.
The environmentalists lamented that we were too late to save them and the damage was done. However, the foresters and land management people discovered that the spotted owls were moving from the "old growth" forests into the tracts of land that had younger timber (second growth) because there was better cover for them from larger predatory birds (Spotted Owls are small) and more things to eat. The moral of this story is, the environmentalists were only monitoring the small tract of land in the primative forest and not looking anywhere else. As it turns out, there are more Spotted Owls now, than before they tried to "save them".
The other example of enviromental stupidity, is the saving of the "endangered river smelt". California has a massive network of aquaducts that feed the agricultural areas and the many cities throughout the state. Over the years, a small fish has moved into the aquaduct system from the Sacramento delta. The enviromentalists have gotten the courts to restrict water flow in the southern aquaducts so it won't endanger the "fragile habitat" of these little fish....that DO NOT belong there in the first place! As a result, the agriculture has been severely compromised, vast orchards have died and many farms have gone bankrupt because of this.
There are many more examples, but now you see what we have to deal with, here...
