well for mankind possibly. Global warming is fucking this planet up, but I believe there will always be some form life on this planet as long as we don't have a nuclear holocaust. Pollution is really bad I could seriously see us digging in landfills in 100 years for raw materials. A lot of garbage is not biodegradable and the trash that is biodegradable is compressed so tightly with the other trash that oxygen cannot get to it and decompose the trash. It all kinda scares me.
