I reported on this briefly before, but have some more comprehensive material stating the dire consequences of the decline in sperm quality and quantity. Here is one of the clear problems people face through not having an interest in scientific issues, since some of these things can kill you, or at least the human race! The sperm decline issue was, as I reported last year, mainly concerned with the West, but a recent study, described below now looks at a worldwide decline, even Africa! Sperm counts have halved in the last fifty years, and here is no end to this. Logically at the same rate, humans will cease to be able to reproduce long before 2070; one prediction is 2045 as doomsday. It will truly be a birth apocalypse. And the problem is going to be difficult to solve given the sheer quantity of hormone-altering chemicals now in the environment.
If the environmentalists want to get scared about something, this is it, but most are so crazy that they welcome human extinction so furry creatures can roam free.
