DDT is a type of pesticide, first made in the laboratory in 1873, but only found useful when Dr. Paul Muller discovered that DDT could kill insects. DDT was used in World War II to kill mosquitoes that carried malaria and lice that carried typhus. Millions of lives were saved during the war because of the effectiveness of DDT.
However, DDT was banned in the United States in 1973 because of its lethal effect on birds. DDT builds up as you go up the food chain, so the higher consumers have the most concentration of DDT. In addition, DDT stays in animals' bodies because it is not metabolized very quickly; DDT is stored in fat, instead. As a result, DDT from fishes end up highly concentrated in the birds that eat fishes contaminated with DDT. Affected birds begin laying eggs with thin eggshells, and the offspring of these birds with high concentrations of DDT are unable to develop properly.
