mark my words, in 200 years, human generation will be able to migrate to another star system. in less than 500 years, earth will be a new place from today what we have.
I think now human being is capable of surviving a comet crash, a massive virus outbreak, a flood on any scale and any major natural disasters earth have experienced in the last 10,000 years.
the same tragedy destroyed dinosaur will not mark the end of human being.
we have outsmarted the mother nature, we may still not be in control, but we are not powerless when facing mother nature. we should be pretty proud of ourselves.
the only thing that can stop or destroy us is ourself in the next 10,000 years.
