You’ll help reduce pollution. Some people become vegetarians after realizing the devastation that the meat industry is having on the environment. According to the US Environmental Protection Agency (EPA), chemical and animal waste runoff from factory farms is responsible for more than 173,000 miles of polluted rivers and streams. Runoff from farmlands is one of the greatest threats to water quality today. Agricultural activities that cause pollution include confined animal facilities, plowing, pesticide spraying, irrigation, fertilizing and harvesting.
You’ll avoid toxic chemicals. The EPA estimates that nearly 95 percent of the pesticide residue in the typical American diet comes from meat, fish and dairy products. Fish, in particular, contain carcinogens (PCBs, DDT) and heavy metals (mercury, arsenic, lead, cadmium) that can’t be removed through cooking or freezing. Meat and dairy products can also be laced with steroids and hormones, so be sure to read the labels on the dairy products you purchase.
You’ll help reduce famine. About 70 percent of all grain produced in the United States is fed to animals raised for slaughter. The 7 billion livestock animals in the United States consume five times as much grain as is consumed directly by the American population. “If all the grain currently fed to livestock were consumed directly by people, the number of people who could be fed would be nearly 800 million,” says David Pimentel, professor of ecology at Cornell University. If the grain were exported, it would boost the US trade balance by $80 billion a year.
You’ll spare animals. Many vegetarians give up meat because of their concern for animals. Ten billion animals are slaughtered for human consumption each year. And, unlike the farms of yesteryear where animals roamed freely, today most animals are factory farmed—crammed into cages where they can barely move and fed a diet tainted with pesticides and antibiotics. These animals spend their entire lives in crates or stalls so small that they can’t even turn around. Farmed animals are not protected from cruelty under the law—in fact, the majority of state anticruelty laws specifically exempt farm animals from basic humane protection.
