Eating Meat-Less or More? Every second in the United States alone,more than 250 animals are slaughtered for food,adding up to more than 8 billion animals each year.Reducing the amount of meat in one's diet is nutritionally, environmentally,and ethically beneficial, People who eat meat usually have weaker immune systems compared to those of vegetarians.Meat has been directly linked to diabetes,obesity,arthritis,and many other illnesses.Furthermore,meat-eaters are at a higher risk for diseases,including cancer,and they are more likely to die from these diseases.Critics say that a meatless diet does not provide enough nutrients,especially protein and iron.Actually,according to A Teen’s Guide to Going Vegetarian,by Judy Krizmanic,proteil1 is found in almost every food,and iron appears in many vegetables.Getting enough nutrients in a meat-reduced diet should not be difficult.A 1988 study found that some of the highest pesticide residues appear in meat and eggs.Diets including more fruits and vegetables will only make people healthier. Some skeptics believe that there will be a shortage of food if animals are not eaten.In fact,the opposite is true.More than 80% of the corn and 95% of the oats grown in the U.S.are fed to livestock.The world's cattle alone consume enough food to equal the caloric needs of 8.7 billion people,more than the entire human population.One half of the water used in the Unites States also goes to livestock;250 gallons of water produces only 1 lb.（磅）of beef.If people eat less meat and more plants,the amount of available food will increase。 Many people become vegetarians because they feel that eating animals is unethical.90% of these animals are raised in confinement.Chickens and other birds have only about half a square foot of space each,and since they are raised so close together,a lot of blade is used to cut off their beaks to prevent them from pecking each other to death.Likewise,pigs that are repressed will bite each other's tails,so both their teeth and tails are removed as soon as they are born. Eating animals is hazardous in numerous ways.Even a slight reduction in meat intake is better than nothing at all.Consuming less meat is beneficial to the health of animals,the health of people,and to the health of the world.
