Re: Yep.
All species, no mater how successful, have eventually become extinct. There is no reason to think human beings will escape this fate. However, we are special. At least we think we are. We are the first intelligent, self-aware, species to exist on this planet. That may make us special enough to survive where others have not. It also may be the source of our demise. If we are to survive, then eventually we will not only have to leave this planet, but leave this star, and solar system. Not to, means we are, as a species, doomed.
