THE EFFECTS OF NOT USING PESTICIDES
Nature is not benevolent to humans who abandon science and technology. There is nothing "natural" about planting fields of crops or raising a herd of domestic animals. Nor is it "natural" for large human populations to live without coexisting vermin and the diseases they transmit.
In the United States each year, pest-borne diseases and attacks by pests themselves still account for hundreds of deaths, thousands of serious disabling illnesses and injuries, and millions of episodes of illness or injury serious enough to require medical attention. Without deliberate human interven-tion, nature would rapidly eradicate the world's food-producing capacity and unleash plagues of long-for-gotten virulence. In short, huge numbers of humans would suffer and die.
Pesticides provide three important benefits. They make possible an abundant supply of food at reasonable prices. They are the first line of defense against food shortages. And they protect health by stopping pest-transmitted diseases and sanitizing food- handing and health facilities.
Properly used, pesticides improve the environment for desirable plants, domestic animals, and human survival.
In prosperous modern America, small-scale experiments in food production without pesticides can be an interesting and occasionally useful diver-sion. However, in countries where food is scarce, such practices can be catastrophic.
Without insecticides, increasing numbers of mosquitoes would spread malaria, yellow fever and encephalitis. Without rodenticides, a growing rat population might produce another epidemic of bubonic plague, the "Black Death" that killed one-fourth of the population in medieval Europe and caused outbreaks in major U.S. cities during this century. Without herbicides, brush would replace grass in rangeland, provoking drought, erosion, and starvation for domestic animals. Without fungicides, many roots and seeds would rot in the ground, and another "potato famine" could occur.
Without disinfectants, hospitals would find it impossible to sanitize their facilities and contain infectious diseases.
Yes, a world without pesticides would not be a pleasant place in which to live.
