It's a childish dreaming that imagines we can must our home to find somewhere better. Powerful visionaries dream of making our home better.

  Where do you live? Is it Odluvai Gorge? The reason humans don't all live in Africa and in fact have colonized almost every inhabitable corner of the planet is because as a species overall we don't think like that. In fact it's the reason we as a species still exist. Life naturally expands to colonize new environments. That's essential because environmental change is inevitable whether it's climate change, volcanic activity, excessive predation or disease. Diversity of location, genetics and culture are essential tools of species survival. Diversity in every way possible is in our Genes. Even within our own cultures, if it's possible for people to live a certain way you're highly likely to find at least some people living that way. Some of these ways of living seem pathalogical. Travelling people, isolationist survivalists, even homeless people but if civilization were to collapse, as it has many times in many places in the past, some of these people would be superbly adapted to survive it or even thrive. For any given place, eventually catastrophe is almost inevitable. We are all the descendants of people who survived some catastrophe or other by moving out before it struck. All of us. In fact that's true of every surviving species on Earth. It's a strategy that works. Let's keep doing it.
