Sci Fi depictions of a blasterd overpolluted, overpopulated Earth bereft of natutal resources is a fear of a bygone era. It isn't likely to happen.

Our technological advancements have already pushed us beyond the points of apocalyptic Maltusian predictions. We are able to feed more people and are more efficient with our resources. We aren't running out of fossil fuels any time soon and we habe become more efficient in it's consumption and we are learning to synthesize fuels. I don't know why we are still being pusjed apocalyptic crap.
