Now that everyone is talking global should I based in India be concerned on depleting rain forests in Brazil?

If whales are being hunted in Japan, norway etc or orrisa cuts down 1,25,000 trees without replanting programmes to make way for a metal industry can countries voice their opinion. should there be a UN [the UN itself is toothless] for the environment where UNSELFISH people with some power around the world, make meaningful changes to the environment [blatant agression is happening presently], which includes our forests, mountains, wild life. If humans dont set up a forum who will, because the others dont have a voice.
