In 2017, epidemiologist Shanna Swan succeeded in showing that the sperm of Western men decreased by 59 percent between 1973 and 2011. Now she warns that many men can be completely sterile as early as 2045 and that human survival may be threatened.
Swan means that the fertility crisis is a threat as serious as the climate crisis and that major changes must take place unless human survival is seriously threatened. Already in 24 years, a very large proportion of the men in the Western world can be completely sterile, she claims.
– It’s a little worrying to express oneself mildly, she states.
