The sun will die in the future and all the people and life will go extinct unless they leave the solar system. This is the most important issue for mankind. We have to leave as quick as possible or else the lineage will end. We can't stay here forever. Colonizing Mars and the rest of the solar system isn't important for long term existence. We have to be able to withstand all the things that can happen at a interplanetary scale or we won't be able to live as long as possible. Does /int/ think it's possible for life on earth to survive forever? If it isn't then what's the point of it all, and what's the point in breeding and all of that. I hope life can survive forever.
