What is something that is growing because of young people?

Inspired by a post I saw on AskReddit (which has now been removed). What is something you believe is growing because of young people?

Young people aren’t having babies. This is a growing global problem. It’s going to get so bad that we won’t have enough people to do all the work needed to support retirees.

It’s going to lead to unrest in many countries as normal services become unmanned and unreliable.

People are finally realizing that the current state of the world is abysmal for bringing a child into. My wife and I don’t plan on kids anyway, but even if we did, there’s no way in hell we could afford to within the next decade, not to mention how irresponsible it feels to introduce a new life to this fascist shithole.
