The most powerful force of nature on the surface of the Earth is the human race. If we were to change our direction away from the pursuit of domination and monopolisation, the world would change for the better.

People are taught to be very aggressive and greedy in our society. If they were to treat their own personal world around them better, that would spread. It would influence the people and animals they come in contact with and make them nicer.

I say this mainly because I've been flabbergasted by people claiming to represent good causes who seem to be uncomfortably aggressive to those around them.

The greatest environmental concern should be to stop the destruction of wild habitats because that is the world itself, not just to count carbon credits but because it would be reprehensible to destroy it.

If you do consider global warming, of course there are many reasons why it's the answer there too. Here's an experiment. Find a place where there is still Rainforest but only few miles away it's been turned to desert, and measure the temperature at both places. Pick any height off the ground, from the forest floor to a reasonable height above the canopy and I bet the difference will be significant, maybe ten degrees?

When and if the leaders of human race learn to wield their responsibilities in a less selfish fashion, I would suggest that large tracts of land, particularly in Africa be protected forests.
