Vegetarians have the lowest rate of atherosclerotic heart disease of any group in the world. The process of atherosclerosis doesn’t just cause heart attacks; it also causes impotence. Meat eaters have a ten times greater risk of breast and colon cancer than do pure vegetarians. On a low fat vegetarian diet 90% of adult-onset diabetics can reduce or entirely eliminate their insulin injections Tens of millions of people are suffering from osteoporosis and kidney failure due to excess animal protein consumption. Meat-eating women have levels of chemical pollution in their breast milk 35 times higher than in the breast milk of pure vegetarians. One acre of land growing broccoli will supply ten times as much protein as an acre of land producing beef.
If acreage now being used for grazing cattle and raising feed grains were growing trees or fibre plants to burn for energy, we would have no need to import foreign oil. More than half of the water used for all purposes in the India is used for livestock production. Water pollution from feedlots and feed grain field runoff (manure, topsoil, pesticides, fertilizer, etc.) contaminates more streams and rivers
In the United States ten billion animals are killed for food every year. Veal calves are chained in crates to prevent movement and fed iron-deficient food to make them anaemic in order to keep their flesh pale. Egg-laying hens are painfully de-beaked, then raised in cages so small that they are unable to stretch their wings. Fishing depletes fish populations, disrupting vital food chains and forcing marine mammals and sea birds to extinction through starvation. Vegans do not eat animal products and therefore do not contribute to the suffering and needless death of animals raised for food.
Plant-based diets only require around one third of the land and water needed to produce a typical Western diet. Farmed animals consume much more protein, water and calories than they produce, so far greater quantities of crops and water are needed to produce animal ‘products’ to feed humans than are needed to feed people direct on a plant-based diet. With water and land becoming scarcer globally, world hunger increasing and the planet’s population rising, it is much more sustainable to eat plant foods direct than use up precious resources feeding farmed animals. Farming animals and growing their feed also contributes to other environmental problems such as deforestation, water pollution and land degradation
