Does Civilizaion have Time Limits? Is extinction possible?

So far, humanity is a one-planet species. Even though we have the technology to be a multi-planetary civilization, we have decided to stay 'home'. Currently humanity is concerned with global warming, food shortages and the possibilities of self-destruction. If humankind becomes a space-faring species, we will have to worry less about these issues. Is it possible that humans are approaching the end of days on Earth? People talk of terraformation, but we do not implement it. Eventually, if we do not leave the planet, humans will die out.

How soon might it be until humans HAVE to evacuate Earth?
