Look there are endocrine disruptors around us, but the radiation that is produced by our mobile devices is non-ionizing. This means that it cannot destroy our dna. The real reason people aren't having children is not because they do not want to, many studies show most people want children, but because it is very expensive to have children. In our capitalist society, children do not act like free labor, they are a burden. Many people want children but their career and the cost of living get in the way. Younger people also don't want to have children as much because we live in an uncertain world where many people don't want to bring children into the world.
