The societal/behavioral changes are interesting, but what about the physiological changes?
Significant declines in sperm counts
Increased medicating; ADHD, Anxiety, Depression, Hormonal Birth Control
Childhood Obesity over 20% in the US
- paulnpace 5y agoOf these, the sperm count strikes me as more causal, while the others may be results of some problem. Granted, the decline in sperm count is caused by something, but in relation to impact on behaviors, the decline will cause (as proxy) changes, and of those changes could be the increased medication, for example.

- paulnpace 5y ago> Sperm count dropping is caused by obesity It may be the obesity decreases sperm count, but sperm count is dropping in people who are not obese. More than a decade ago there were reports on studies where the authors made simple extrapolations that sperm count would be zero by 2050, but these simple extrapolations are holding true in today's trends.
- spywaregorilla 5y agoI searched for a source to credibly defend that statement and have found none. I'm open to being shown otherwise. Some studies will bin people by BMI or some metric but fail to do any analysis on whether people aren't fatter within the bins. E.g. if the bell curve shifts right, the average weight of people within the slimmest band will still be heavier than before; even if the maximum BMI/weight is still capped at the same upper bound. And the deltas on sperm counts within healthy weight ranges are very small in most studies to begin with. edit: searched in the past; not the few minutes since your comment*
- paulnpace 5y agoThe observation that sperm count is dropping and your claim that obesity reduces sperm count is not an explanation. You have made a positive claim that the observation in broad drop in sperm count is due to obesity. Now present your evidence.
- rkk3 5y agoMy understanding is that obesity is a factor but not wholly explanatory, especially because there are documented sperm count declines in other species (Dogs)
- spywaregorilla 5y agoDog obesity has more than doubled since 2007 based on the first google result I could fine.
