Vegetarianism According to a recent statistic, there are as many 6 to 8 million vegetarians in the US alone. This staggering number indicates that vegetarianism is not just a present- day fashion. However, many meat- eaters still vigilant about the balance of a vegan diet. In my opinion, I am in favour of vegetarianism because of several reasons. One of the most outstanding reason is that many people choose a vegetarian diet for moral of health reasons. After sticking to vegan diets, people are apt to be more serenity because of not questioning the treatment of animals in factory farms. Furthermore, a balanced vegetarian diet can help human lower the risk of a number of diseases, including cardiovascular disease, cancer, diabetes and obesity. Vegetarians just eat vegetables and fruits, that can effectively cut down on fat and protein which are high in meat. Therefore, people can maintain a healthy weight and a good shape as well. Another important reason is about pollution. More specifically, a report estimates that the industrial raising of meat animals generates about a fifth of the world greenhouse gases. Moreover, it either increases the usage of other pollutants such as pesticides and consumes large amount of scarce resources, including water, land and oil. As a result, by eating million tons of meat per day, humans are destroying their own environment. In that case, vegetarianism is obviously a more eco- friendly lifestyle. In addition, to some extent, meatlessness is also a useful measure of animal conservation.
