Theory #2

Do you ever wonder what would happen if global warming caused the earth to "wear out" sooner than we imagine? What would happen if, you know, all human-kind is forced to go somewhere else because what we have done to this amazing planet? Will we have an alternate place to go?
See, I believe that scientists should be prepared for any possibility. Anything could happen at any time, everyone should be prepared...which means that scientists should be prepared for all those people. Do you think scientists get it? Do you think they get that any time all of this could end? Do you think we get it?
Overall Question: How long do you think will make it if we keep living this way?
I don't know...
