It's obvious that they are only after control and imposing their wills on everyone else and not protecting any environment.
I've often wondered why they do that. But any organization, no matter how evil, will find constituents. Consider all the people who might want to contribute to these environmental obstructionists:
1) Lumber industries in countries that don't restrict logging and can profit by selling to the US.
2) People who want home prices to rise i.e., those who already own homes and apartment buildings.
3) Nature worshipers who think humans are a cancer on the planet.
4) People in other countries who despise the US and will do anything to weaken us.
5) People who sell alternatives to forest products.
6) The obstructionists themselves who will take "contributions" in exchange for going away and bothering someone else.
It pays, and it's all just another form of terrorism.
