"We still have this massive problem that clearly points towards human source(s). And equally as clear is that the solution is in our hands as well"

Many people, myself included, believe this not to be true. That what we're seeing is part of a series of complex natural cycles that owe (virtually) nothing to man's influence. That's not an uninformed opinion, but one grown from scientific training and review of currently-available objective data. It's still an opinion of course.

I think we should be devoting our energies on how to cope with what's happening, not fruitless attempts at trying to stop it. The coral dying, deeply regrettable though it is, is minor compared with many other changes in the offing.

I do accept that those changes that can be attributed to human influence, such as pollution of the oceans and unsustainable fishing procedures, should be tackled. Unfortunately there seems little will to do this.

The UN is not an ideal organisation but it's all we've got. Rather than condemning it out-of-hand we should be trying to make it better. The whole world is moving towards these supra-national organisations, and many of the problems we see are structural rather than to do with individual people. And please God the USA does not revert to the isolationism that so nearly led to global disaster 60-odd years ago.
