The question is why are these environmentalist groups not for immigration control! They have a Stalinistic way to purge the "green nativists."The main example that comes to mind is the Sierra Club. The reason is that they wish not to associate themselves with us the deplorable xenophobes! They are so afraid to be called racist, and have no scientific argument for not opposing immigration. Some even say that the reason is that now climate change is the new green issue. These people dont truly care for the environment, they just follow the fad. Immigration Restrictionism is a pro environment issue, and all environmentalists should be for it!
As Tancredo states, true environmentalists may be drawn to Trump (or at least they should) for his stance on immigration control.
All green liberals need to vote Trump, or by 2050 we may have over 450 million people, and a destroyed country!
