1。素食主义的简介
Vegetarianism is the practice of following a plant-based diet including fruits, vegetables, cereal grains, nuts, and seeds, with or without dairy products and eggs. A vegetarian does not eat meat, including: red meat, game, poultry, fish, crustacea, shellfish, and products of animal slaughter such as animal-derived gelatin and rennet.[1] There are a number of vegetarian diets. A lacto-vegetarian diet includes dairy products but excludes eggs, an ovo-vegetarian diet includes eggs but not dairy products, and a lacto-ovo vegetarian diet includes both eggs and dairy products. A vegan diet excludes all animal products, such as dairy products, eggs, and usually honey. Many vegans also seek to avoid using any other animal-derived products, such as clothing and cosmetics. Vegetarianism may be adopted for ethical, health, environmental, religious, political, cultural, aesthetic, economic, or other reasons.
Semi-vegetarian diets consist largely of vegetarian foods, but may include fish, poultry, dairy products, and eggs. With these diets, the word "meat" is often defined as only mammalian flesh.[2][3] A pescetarian diet, for example, includes fish but no meat.[4] The common use confusion between such diets and vegetarianism has led vegetarian groups such as the Vegetarian Society to note that such fish or poultry-based diets are not vegetarian, because fish and birds are animals.[5]
2。简要介绍素食主义的优缺点
Health benefits and concerns
Vegetarianism is considered a healthy, viable diet that can aid in keeping body weight under control, and may provide benefits in the prevention and treatment of certain diseases, such as heart disease.[20] Necessary nutrients, proteins, and amino acids for the body's sustenance can be found in vegetables, grains, nuts, soymilk, eggs and dairy.[21] The American Dietetic Association and Dietitians of Canada have found a properly planned vegetarian diet to satisfy the nutritional needs for all stages of life, and large-scale studies have shown that mortality from ischemic heart disease was 24% lower in vegetarians than in nonvegetarians. Vegetarian diets offer lower levels of saturated fat, cholesterol, and animal protein, and higher levels of carbohydrates, fibre, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals.[22]
Vegetarians tend to have lower body mass index, lower levels of cholesterol, lower blood pressure, and less incidence of heart disease, hypertension, type 2 diabetes, renal disease, osteoporosis, dementias such as Alzheimer’s Disease and other disorders.[23] Non-lean red meat, in particular, has been found to be directly associated with increased risk of cancers of the esophagus, liver, colon, and the lungs.[24] Other studies have shown no significant differences between vegetarians and nonvegetarians in mortality from cerebrovascular disease, stomach cancer, colorectal cancer, breast cancer, or prostate cancer, although the sample of vegetarians was small and included ex-smokers who had switched their diet within the last five years.[25]

具体介绍5.3Environmental
In addition, animal agriculture is a large source of greenhouse gases and is responsible for 18 percent of the world's greenhouse gas emissions as measured in CO2 equivalents. By comparison, all of the world's transportation (including all cars, trucks, buses, trains, ships, and planes) emits 13.5 percent of the CO2. Animal farming produces 65 percent of human-related nitrous oxide and 37 percent of all human-induced methane. Methane has about 21 times more Global Warming Potential (GWP) than carbon dioxide and nitrous oxide has 296 times the GWP of CO2.[152]
Animals fed on grain, and those that rely on grazing, need far more water than grain crops.[153] According to the USDA, growing the crops necessary to feed farmed animals requires nearly half of the United States' water supply and 80 percent of its agricultural land. Additionally, animals raised for food in the U.S. consume 90 percent of the soy crop, 80 percent of the corn crop, and a total of 70 percent of its grain.[154]
According to the theory of trophic dynamics, it requires 10 times as many crops to feed animals being bred for meat production as it would to feed the same number of people on a vegetarian diet. Currently, 70 percent of all the wheat, corn, and other grain produced is fed to farmed animals.[158] This has led many proponents of vegetarianism to believe that it is ecologically irresponsible to consume meat.[159] Rearing a relatively small number grazing animals is often beneficial, as observed by the Food Climate Research Network at Surrey University, which reports, "A little bit of livestock production is probably a good thing for the environment".[160]
环境的这个，我自己扫了下，给你挑出来的。
