Sterilize the males. Just take a sperm sample to be frozen and stored until they desire to have children. That should do it.
Seriously, overpopulation is not the problem. It's how resources are managed is the problem. I have traveled hundreds of miles across empty terrain and there is lots of room for everyone. It's the lifestyle that needs to be altered. Besides, somehow, I think, based on some who have traveled to the future that there will eventually be floating cities. In fact, my current primary concern is the destruction of the planet by pollution as a result of those responsible who just don't give a damn about the contamination of earth, air and water. Just think chemtrails, Gulf of Mexico and Fukashima for starters.
