People choose vegetarianism as a lifestyle, diet and trend, and for religious purposes. In the United States vegetarianism only started to grow about 20 years ago, this has caused a lot of false information to circulate which ultimately clouds people's opinion on being vegetarian. For example, people don't believe that a vegetarian diet is as healthy as a meat-based diet, but they can get all the nutrients from a diet that doesn't include eggs and meat. If people don't know the truth about vegetarianism, how can they have a valid opinion? It's not just a diet, it's a healthy lifestyle. The real fact is that people who adopt vegetarianism will find that it is the simplest and most practical way to save the environment, end world hunger and live healthily. In 1991, when comparing the amount of water needed to prepare different foods, results showed that following a vegetarian diet saves water. To prepare one kilo of beef, approximately 2,500 liters of water are consumed, but only 220 are needed to produce one kilo of tofu. If people prepared or ordered more vegetarian meals more often, they would save 1,000 liters of water for every pound of food. This shows how much one person can do to reduce water waste around the world. Most livestock and poultry are overfed, and each year large amounts of food are wasted feeding these animals. What people don't realize is that 10 pounds of plant protein is used to produce one pound of beef protein (Fiala, 2009). If more people were vegetarians, fewer livestock would be needed, and all this food could be used to feed millions of hungry people. people all over the world. Even if the food did not reach the suffering people, food prices would eventually fall and make food more affordable for the poor. From personal experience, India has the largest number of vegetarians in the world and is one of the cheapest countries for food and water. This may require the intervention of numerous vegetarians, but it is one of the best options we have to help those who are suffering. Nathan Fiala (2009) also studied the effects of meat production on greenhouse gas emissions (carbon dioxide and methane are released into the air). His study concluded that producing the annual amount of beef consumed by the average American emits as much greenhouse gases as a car driven more than 1,800 miles.
