DDT is an insecticide that can pass up in the food chain i.e. from insects to small birds, and then from small birds to big birds like hawks. High concentrations of DDT in birds leads to weakness in the egg shells.
This leads to a decrease in their population so we can conclude that DDT has adverse affect on our environment due to its presence for a long time.
