The future is cloudy, I don't know if we would have died by war by that time, or if we would fall victim to disease and die out. Those are the two ways I think the Human race will go out.

Global warming may well play a part too.

I'd be more worried about various cancers we would get from radiation from the sun since we are beating the shit out of our ozone, not to mention the effect it would have on our crops, if we are lucky only the leafy plants will die out. We could live on beans and potatos!
