>These days, scientists say, an increasing proportion of sperm — now about 90 percent in a typical young man — are misshapen, sometimes with two heads or two tails. Sperm counts also appear to have dropped sharply in the last 75 years, in ways that affect our ability to reproduce. 

>One recent study found that of sperm donor applicants in Hunan Province, China, 56 percent qualified in 2001 because their sperm met standards of healthiness. By 2015, only 18 percent qualified. "The semen quality among young Chinese men has declined over a period of 15 years," concluded the study, which involved more than 30,000 men.

Perhaps even more alarming...

Alarming?   Surely this is great news for the planet.  Anything that reduces the fertility of humans has to be good news, doesn't it?
