People must realize that we LIVE on Pandora. Part of the problem (related to some folk's depression is that they are so removed from nature that when they see Avatar they wish they lived in such a world). I say people should put away their tech toys and step out more.
That would definitely help. We are too disconnected from nature. I think we need a whole lot less classroom time and a lot more time in the great outdoors being with Nature and learning survival-type of skills, as well.
