Future of mankind

What do you think will happen? I think space settlement seems pretty interesting, though I can't really decide on its likelihood. Space settlement, it seems to me, would also cause humanity to branch off into separate species, since the requirements for life in space are different than on Earth.

With growing population and technology, the future's pretty much open for anything, assuming we don't blow ourselves up too soon.

http://future.wikia.org/ is a nice site on this.

Ask that question again in 100 years.

     When people think of resources often they think of food and fuel, but our metals are running out as well. There's enough useful metals on a single asteroid to provide the worlds metal production for something like, a few dozen thousand years. It's not like we have to go and live on the moon to put it to good use for us. The same goes for all of space.
     People also think we are running out of room here on earth, but that's not why we should expand into space at all; think of all the biodomes we could build out of an asteroid. Places with low population density like northern Canada and Russia could become medium density. We would have plenty of room for billions more. And there's Antartica too, but that has less access to other countries around it, so that's a bit more of a stretch.
