<p>The Ethics of What We Eat by Peter Singer will give you the most comprehensive ethical reasons for being a vegetarian. I highly recommend it. The choices we make in regards to food have global implications. The first is the obvious pathos-inspired argument: factory farming is not natural and is not justifiable. It is not the result of gratuitous sadism, but reflects a market that refuses to look at the suffering of other beings if it not going to be profitable. In example, no anesthetics for the castrated pigs (and they need to be castrated because americans want an larger cut of meat and don’t want “boar taint”) or de-beaked chickens. Speciesism (discrimination based on species, just like racism or sexism) is not a fair justification for meat consumption nor is enjoyment of it. Factory farmed meat is also incredibly unhealthy and appalling. It’s incredible how many hormones and antibiotics are actually allowed in these animals. America is not nearly as strict as places like Europe in this regard, and things like BGH (Bovine growth hormone) have been banned overseas. When and if people do eat meat, I personally think it should be organic both for ethics and personal health. In China, a diet of 1/10th of the meat the Standard American Diet (SAD) allows has given them longer, healthier lives. The standard american diet is much too heavy on animal products, and so you have ethics in a global and environmental context. If everyone in the world ate the way the typical American does, a U. Chicago study showed that the world would require 67% more land than is actually present on this earth in order to feed everyone. This is because you’re not eating food directly. You’re growing grains and corn and feeding it to animals and not getting nearly the same yield. Ex: 13 pounds of grain for 1 pound of beef, 6 pounds of grain for 1 pound of pork or chicken. Also, beef is probably one of the most wasteful foods eligible for consumption, requiring 1820 gallons of water for 1 pound of beef! Another study showed that switching to a vegan diet saves 1.5 tons of CO2 emissions per year, more than switching to a hybrid car. This is just a snippet of the impact eating meat has, and here’s one more comprehensive quote to show the global implications: One hundred million tons of corn is annually turned into biofuel that goes into American gas tanks. Thats a lot less corn available for export, and so it contributes to higher world grain prices. But most corn isnt eaten by humans; its eaten by animals, and thats where the biggest part of the food crisis starts. The amount of grain and soybeans fed to animals has increased sharply over the past decade as Asian nations have become more prosperous and their citizens have started eating more meat. [insert lots of statistics here to prove increase - ex: china, in the two decades up to 2006, cattle production went from 5 million to more than 50 million.] According to the United Nations Food and Agriculture Organization, 756 million tons of grain were fed to animals in 2007. Just to give you a sense of how much grain that is, imagine it equally divided among the 1.4 billion people living in extreme poverty. It would give each of them more than half a ton of grain, or about 3 pounds per day, which gives you twice as many calories are you need
When we use animals to convert crops into meat, eggs, or milk, the animals use most of the food value to keep warm and develop bones and other parts we cant eat. Most of the food value of the crops we have grown is wasted-in the case of cattle, we get back only 1 pound of beef for every 13 pounds of grain we feed them. With pigs the ratio is 6 pounds of grain to 1 pound of pork. And even these figures underestimate the waste, b/c meat has a higher water content than grain. The world is not running out of food. The problem is that we the relatively affluent - have found a way to consume 4 or 5 times as much food as would be possible, if we were to eat the crops we grow directly. -Peter Singer, The Life You Can Save, p 122 (I’m a huge Singer fan).
There are SO many reasons for going vegetarian, and not just health. </p>
<p>@Fauxmaxen While I’m not proposing that her daughter go vegan (at least not immediately), I disagree with your assertion. I’ve been vegan since I was 15 (I’m now 18), and I am much healthier than most of my peers. There are just a few things that one needs to be aware of: B12 and iron. Easily fixed with supplements - iron supplement and multivitamin. I get b-12 from nutritional yeast and spirulina tablets. All of my blood tests have come out even better than when I was an omnivore. I hope that more and more people go vegan because it does matter.</p>
