We're like bacteria in a pitri dish. Overpolluting the environment. We're due for a die off. Not sure how far away that is, but we certainly have a worldwide economic collapse looming. It might be a slow die off, too.
Future prospects are economic collapse, government dissolution, civil unrest, an emerging sex/drug/indulgence/seclusionary culture, and probably a rise of communism.
On a larger scale, yeah, we're killing ourselves. THat seems inevitable to me.
