Nice reply. Yes things can be done. It's too bad we don't do the simplest first. For instance have groups (corporations with one purpose) buying land in places like the Amazon, Indonesia, the Congo and then doing "nothing" with it.
Personally I think that industrial waste (which doesn't have a one-to-one correlation with global warming / climate change) is a far greater problem.
Yes, Industrial waste is a great problem. It is among the aftermart of anthropogenic activities.
