We are frequently told by vegetarians, vegans and animal rights supporters that by eating meat we are fueling a market that supports cruelty to animals through slaughter and abysmal living conditions. Those who truly love and care for animals would either become vegetarian or buy meat from farms that do not treat their animals horribly (although of course the animals would have to be inevitably slaughtered which arguably makes this point irrelevant). Vegetarians and vegans hope that, by not eating meat (and animal products in the vegan case), they will be able to create a fall of demand in meat products and thus a decrease in animals slaughtered. However the truth of the matter is that eating meat does not only cause undeniable cruelty to animals…
According to several independent investigations, about 760 million tons of crops are fed to livestock each year to cater meat eaters . Imagine if the whole world were vegetarian…those 760 million tons of extra crops would not only end world hunger for centuries to come but the millions of tons would also create a surplus capable of sustaining even greater global populations (this will be needed as the human population is still growing at a massive rate). In an investigation the Department of Agriculture noted that one acre of land can potentially grow 20,000 pounds of potatoes…however an acre of land used to create cattle-feed can only generate a maximum amount of 165 pounds of cow flesh . With 40,000 children needlessly dying of hunger everyday…the legitimacy and morality of the meat industry, and perhaps even meat eaters themselves, should be questioned.
In the United Nations’ environmental report, Livestock’s Long Shadow, the UN noted that eating meat ”is one of the most contributors to the most serious environment problems, at every scale from local to global.” In one of the many examples of the report, eating meat causes almost 40 percent more greenhouse gas emissions than all the cars, trucks, and planes in the world combined. The report concludes that the meat industry “should be a major policy focus when dealing with problems of land degradation, climate change and air pollution, water shortage and water pollution, and loss of biodiversity.” 
I myself am a vegetarian…mainly due to the points already mentioned as well as for health reasons (my family has a long history of illnesses that are caused by the consumption of meat). However I do not endorse vegetarianism to my peers and my family (the latter being completely against my vegetarianism) because I know that eating meat is part of their life. I also know that as omnivores, it is natural for the human diet to consist of meat products. Notwithstanding I believe that it is still worth knowing all these facts before eating meat at your ease.
