>Compared to our ancient ancestors, we are shorter, slower and we have been losing mental capacity for thousands of years. And just this week, a groundbreaking study that discovered that large numbers of human males in the western world may soon be incapable of reproducing made headlines all over the planet…

>Humans could become extinct if sperm counts in men from North America, Europe and Australia continue to fall at current rates, a doctor has warned.
>Researchers assessing the results of nearly 200 separate studies say sperm counts among men from these areas seem to have halved in less than 40 years.
...
>The 185 studies that the researchers took their data from were all conducted between 1973 and 2011. Dr. Hagai Levine was one of the lead scientists involved in the study, and he found that for men in North America, Europe, Australia and New Zealand, sperm concentrations declined by 52.4 percent during the study period, and total sperm count declined by a whopping 59.3 percent.

>“Eventually we may have a problem, and with reproduction in general, and it may be the extinction of the human species.”
...
>“We think this is being caused by a heating of the sperm from the phone and by electromagnetic activity.”

>Findings going back to 2002 show that the human mutation rate is at least 100 mistakes (misspellings) per person per generation. Some scientists believe the rate is closer to 300.
...
>DNA mutations are passed from one generation to another, and each generation has more mutations than the previous generation.
>This process appears to be accelerating, and at some undetermined point in the future human DNA will become so corrupt that the human race simply will not be able to continue.

Lots of links for the claims are in the article. There is a chance the West (or humanity) is slowly killing itself with its advancements (as well). Implying more primitive societies have better breeding chances.
