DDT is a powerful chemical that can kill living things. When farmers spray DDT on their farms, the rodents and other small mammals in the farms vicinity die. Spotting an easy meal, birds of prey like eagles, vultures etc pick them up. As a result, the chemical enters the birds body causing diseases and even death in most cases. DDT also causes the birds to lay eggs with very thin shells. The thin shelled eggs break easily and the embryo will die.
