Society fails to realize that the pesticides being used are actually killing other animals and human species through the contaminations in it, that’s made by man on earth because we humans and the animals eat those crops. The quote, “The central problem of our age has therefore become the contamination of man’s total with substances…

    After World War II (DDT)

    During the use of DDT, after World War II, crop yields increased greatly in the United States and overseas.

When the chemical was made available to the American public, it was welcomed as a means of boosting agricultural production, suppressing pests, and protecting shade trees, orchards, and gardens” (Forman). Due to the increase in crop production, there was a greater abundance of crops available for the citizens of the countries that used DDT as a pesticide.…

Organisms can also have foreign genes inserted into them, almost the same thing as Genetically Modified Organisms but they come from animals, plants, and sometimes humans, instead of other foods (GMO Education).…
