Human colonization of Mars and other planets and moons should be on that list. And I'm not just saying that because I'm a Sci-Fi fan. (Though TBH it's a large part of it :P) It's also because I believe it would help solve some of the other problems presented here. For instace: once we're able to build whole cities on Mars and are able to transport humans from Earth to those cities with relative ease (which, of course, is at least decades away), the need to destroy enviroments to build more urban sprawl would diminish, thereby (hopefully) preventing overpopulation (and therefore mass poverty) as well as helping the eviroment. On top of that, right now, if Earth is doomed, humanity is doomed. So why should Earth be our only home? It would take decades to build full settlements on mars, but only about 15 to 20 years to prepare and begin. So we should start as soon as possible.
