I suspect this too.I used to think it was the cell phone radiation, but in that case, older people should be getting depressed at the same rates as young people. I actually think it might have something to do with GMO food after listening to Peat's last interview -- Dr. Peat said the effects of eating GMO don't really show up in the consumer of the food but in the offspring, who are born less and less fertile as the generations continue. By the third generation most of the world will be completely infertile. I would guess we are in the 2nd generation since the green revolution started in the 60s. Which means 90s babies are the first generation to be born from parents who grew up eating GMO food. But it's not hopeless because our good friend CO2 is capable of reversing epigenetic changes if we get enough of it.
