The environmental movement has been hijacked by the socialists and communists as long as I can remember. It was being discussed at least as far back as the late 1970's and early 1980's.
Since then is was never actually about the environment ever, but rather how to gain support for socialism and communism. This Green New Deal is a prime example of that actually. The job guarantee, Basic income, and universal health care provisions of the GND is proof of that.
It's nothing more than old fashioned "kiss the baby" politics, restyled for modern consumption.
In the old days they would proclaim awww look at him. He cares for the children, we must vote for him. Later they said, awww look at him. He wants to save the whales, we must vote for him. And now awww look at her. She will save us from global warming, we must vote for her.
Except it never is about the cuteness, it's about hiding the true purpose behind the cuteness. So people that really do want to save the children, save the whales, and save the world from global warming get tricked into supporting a whole lot of other policies they may or may not agree with at all!
And in this case anyone showing opposition to the Job guarantee, Basic income, and Universal health care provisions, will instead be proclaimed to be anti-environment, or causing global warming.

Like somehow they time traveled back to the beginning of human civilization and started all this mess on purpose.
As illogical as that may be just look at your own post! You just made the exact same error in assuming all political opposition to environmentalists was against the environment!
