What do you think it will take to reverse the effects of global climate change?

This problem is greatter than all problems. We need to resolve it.

I hate to say it, but I don't think we can. We'd have to STOP burning things that emit carbon into the air - so no more burning fossil fuels, like coal, gasoline, etc. We would have to stop ruining our soil (because salinated and ruined soil can NOT naturally manage manure - which emits more greenhouse gases into the air) To stop ruining our soil, we would HAVE to stop till farming and pesticide/fertilizer farming. ACtually.. we would have to reduce the population of humans and stop faring all together and go back to hunting and gathering. Which is why I think we can't fix it. OUr society would never let us go "backwards" that far, which is too bad, because this lifestyle is much more healthy than what we have now. Some of the damage we have done to earth is IRREVERSIBLE. We can't get back the soil we ruined that has become desert. We can't get the soil back that we allowed to erode into oceans and seas. We can't rebuild the ozone layer. It's very sad. In 500 - 1000 years, there won't BE any people left on this planet. And we'll take hundreds of thousands of species of plant and animal life with us.

Well, we need to stop polluting, and start to respect the environment ! But we need to be supported by the principal governments of the earth (Like the USA) otherwise it won't work ! Good bye, crazyrk.

very serious and it will take a couple hundred years to change- if at all possible.
