Do You Ever Wonder Why Young Men Have Breasts Now

I was reading a weekly paper today and there was an add for male breast reduction. This is not a result of natural selection. Why do men under 35 have breasts now? Men born in the 1950s and 1960s don't have breasts. So, what has changed? What has changed is our food. What has changed is the hormones that we give to chickens and other animals. Why doesn't this bother anyone? Why doesn't it bother people that we are genetically modifying our crops?
