Here something to think about we are over population of the earth with limited resources for us and other species. Mankind has become greedy and destructed to the only place we call home. We polluted air , land , and even water bend repair and also kill and eat anything we want without thinking about the Consequences of are action to effect it has on us and any other living things.
So here doomsday scenario if we only a few months to live from in coming comet or asteroid . Should we try to stop it or let it wipe the slate clean and earth start over again.
It maybe crazy but would let wipe out everything to give planet fresh start again from all destruction we cause.
