I BET YOU CAN GUESS WHAT KINDS OF CHANGES THEY THINK OUGHT BE MADE:  UN: Huge changes in society needed to keep nature, Earth OK.

I have an idea. Get rid of the UN, much happier people. Then get rid of socialism and communism, to keep nature, the Earth okay. There. End of discussion. (Truly, totalitarian societies are ecological disasters and the darlings of the UN.)
