I propose that the more people on the planet, the less living in poverty. The more people there are, the more likely that some will figure out how to solve these problems. I've noticed that the people around me with more children work harder and figure out how to make money, because they really need it. Imagine a big field of sweet potatoes growing. A small family could farm some of them. But, if 100 neighbors came over in rotating shifts, there would likely still be enough sweet potatoes for everyone. And, then they all would learn how to grow sweet potatoes, and probably better, too. Problems arise if the original farmers say "nobody else in the world can grow sweet potatoes." But, if you can prevent that, there should be enough sweet potatoes for everyone.
