In the 1700s Thomas Malthus nailed the problem by mentioning overpopulation. Things have only gotten worse and it is now off the agenda for political reasons. Hollywood just introduced usball to Thanos who did something insane to deal with the problem.

I could site the census I guess, but I don't really hear anyone arguing more and nore and more people will solve the problem (well the more people the mpre climate scientists I guess).
