I'm driving a complete circumnavigation of the continent - I have just driven through 21 countries in West Africa, and I'm aiming North to drive through another ~15 in the next 12 months [1] I have also driven Alaska - Argentina [2]
The more I travel, and the more I see and learn about the world, humans, population and the environment, the more I am dead-set on the idea of mandatory population control. We need to put limits on how many children a couple can have. I know China's policy had some serious downsides, but at this point I fear much, much worse if we don't.
Let's reverse the trend and start offering financial rewards to people that don't have children.
