The destruction of our mother nature, is what is killing me inside. To know we are facing problems that are nearly impossible to solve. Our very economy is based on the fundamental problems: power and money (materalistic items). Every other problem can be broken down to those two. We eliminate those we get one thing everyone with a brain wants: peace and tranquility. And hopefully, that would lead us back to our natural selves. There are many other factors, of course, but these are the most significant. Get rid of those, greed will be gone, and the need for fossil fuels can actually be replaced by environmental-safe sources, as greed (being the fuel for fossil fuels, which is the biggest source of money, which is also the reason there are very few environmentally-safe energy sources because they are dirt cheap in comparison, giving oil diggers less money)...
See what I mean? Only problem is: it is not going to happen without radical changes. And due to the fact history seems to repeat, and our current path has happened to many other civilizations, means that it will continue to other civilizations. Until death do us apart. Sickening, disgusting, but very, very true.
Eywa/God/Gaia help us all! Before it is too late!
