A conference of 130 environmental groups declared that you can only stop global warming by changing the “capitalist hegemonic system”.
Wanna bet they all Facebooked that from their iPhones?
[re: the title – what’s the term for a group of environmentalists?]

what’s the term for a group of environmentalists?
a flush
a commune
A Goreuption?
An injunction?
I think there is a clue in the name of their paper…”Margarita Declaration”. Perhaps a “Buffet”? http://youtu.be/KCcXqFCMSbo
…a handout
…an occupation
…a protest
…pollution of environmentalists – that’s my favorite
A “dire” – the earth will be destroyed!
“Conspiracy” also works.
An “anger”
An “ego”
A “nanny”
A catastrophe.
A falsehood.
A projection.
A propaganda.
An asylum
a cell
a jihad
So what do they want to change the capitalist hegemonic system to, communism? Good idea, everyone knows that communist countries don’t pollute.
A nag, or perhaps an annoyance, reflecting the facts that the environmentalists are annoyed and that they annoy productive humans.
@Jim I think you’re missing the point. It’s not pollution that causes global warming, is capitalism. Pollution produced by communists is completely non-polluting.
I believe it’s a scold of environmentalists
