Pesticide Usage

Pesticides are considered a necessary evil today. The use of pesticides has progressively increased over the last few decades. Prior to World War II, a few inorganic pesticides were used on a negligible scale. The use of synthetic chemicals as pesticides started with the invention of DDT (dichloro diphenyl trichloroethane). Since then, the use of pesticides has grown enormously both in terms of the number of pesticides and the volume of the use of pesticides. The use of synthetic pesticides supports a large number of industries and involves business worth billions of dollars.
