@namelus,
According to several reports, world population is dropping off. Japan and Italy have a big population problem.
Meanwhile, the Western males are seeing a decrease in sperm quantity and motility.
Toss in the legalization of pot (HTC decreases the motility of sperm) and we are well on our way to decreasing our own population.
There have been a few reports suggesting sedentary lifestyle, the ultra-processed food stuff, various chemicals in plastics are all contributing to low sperm counts.
Population reduction? We are doing it to ourselves.
