Today, the speed of introduction of new products, medicines, chemicals etc. are way beyond the pace of those chasing the effects. Think back at PCB for awhile. PCB is accumulated in the body of all living things. It is a stable substance like DDT and does not break down. Our kids inherit our problem.
Kids are more vulnerable than adults.
Toxic levels that kills the young can mostly be whitstood easily by adults. It is just too probable that we create a situation where the next generation cannot survive. We have introduced gigantic systems worldwide without knowing the results to the enviroment or to us. During the first two decades of this century, the world was electrified. During the world war, the world was enveloped by radar.
