Choose an environmental challenge(e.g. climate change and global warming, desertification, pollution, ozone) that the world is now facing.
1) Identify the current threat it poses, and the efforts the international community has put forward to resolve this problem.
2) Be sure to identify the main organizations and international regimes of action.
3) Finally, give your views on the progress of the international communities’ efforts on your issue, what future efforts do you think will be necessary?
