Wouldn't most of the world's problems be solved if people had less kids?

Bear with me because this might be a doozy. In my opinion, many of the worlds problems would be solved if people chose not to have alot of kids or in some cases, not have any at all. If people had less kids and the world population dropped a little bit instead of multiplying every year, there would be so many more resources to go around which would lead to less wars. There would be more food to go around, more space to go around, more jobs to go around, not as much trash aculating in landfills, less forests getting cut down, less future drivers driving their pollution inducing cars, and overall less people to leave their carbon footprint on this planet. Im not saying that there should be a law for this sort of thing, I am just saying that people need to be more aware. In my opinion, some people should just flat out not breed while the responsible people should stop at two kids if possible. I say two kids should be the max if possible because it atleast gives the first born a chance to have a sibling. It would also help if people learned to not be so wasteful. So before I begin to go off topic, wouldn't most of the world's problems be solved if people had less kids?
