We should send all the poor overpopulated starving people of Africa to Australia, move Africa next to North America (or build a bridge from Miami to Morocco), and use it for more colonizing space. Like really look at all those silly reservations and open space for wildlife that we could build on.
And then all the starving Africans can have as many babies as they want and can eat sand, snakes, and kangaroos and they'll never go hungry again.
