Say no to sex!
Sex is polluting our world in a nasty way. People walk around thinking about sex way to much and this takes time from being productive. We could actually have a world where people can afford to live (that differs a whole lot from today, I'm talking about Africa). If we all started producing instead of having sex there might just be enough resources for everyone.
It's really this simple, everytime you have sex you ravish a small African country.
I'm joking, here is the real reason: Girls having sex for money.
