Are you sure humanity is going to get there, and survive, before they run out of resources to build what's needed for such a thing here on Earth?
Also even if we do that, there's only a tiny fraction of the people on Earth that will be able to go on that journey. Most of the people born here are definitely stuck here.
There are predictions that some of these things could start happening as early as 2050 (specifically the extinction of edible seafood one), and most of what I mentioned maybe happening by 2100. Is the majority of people here still alive at that time going to be off this planet then?
