I used to eat meat throughout my childhood, but never really enjoyed the taste. Only after a graphic showing of a pig slaughter I witnessed in elementary school did I stop eating pig, and once I was in high-school I became of full-on vegetarian. My main reasoning for this was more that I disliked the taste of meat, but the ethics against killing animals was a reasoning as well.
I soon learned that there was another great motive to becoming vegetarian; the negative environmental effects of meat production . There are a variety of different environmental impacts that occur due to the production of meat:
- Air pollution due to dust and liquid manures.
- Fossil fuels, water, and land over-use
- Rainforest erosion and destruction for pasture land
- Water contamination due to animal waste
- Grain and corn grown for animal feed instead of addressing world hunger
The two natural resources that are perhaps most tapped by meat manufacturing are land and water. According to the British group, VegFarm, a 10-acre piece of land can feed 60 people when used for the production of soybeans, 24 people when used for wheat, 10 people when used for corn, and only a mere 2 people when used for cattle. Similarly, the amount of water used is severely disproportional when comparing wheat to meat. In a book written by Paul and Anne Ehrlich, one pound of wheat uses approximately 60 pounds of water while one pound of meat requires about 2,500 to 6,000 pounds of water.
Another issue that the EPA is specifically interested in is the pollution that feedlots and animal wastes are causing in waterways . The runoff from feedlots and animals feces-covered fields is causing some of our waters, such as areas in the Chesapeake Bay, to become unhealthy.
Regulations can be made to help prevent the effects of meat production, but the easiest way to lessen the environmental impacts is to become a vegetarian or vegan. The vegetarian/vegan alternative can be easily accomplished in today’s markets and restaurants. Meat substitutes including tofu, seitan, and soy-based products are more easily accessible in grocery stores and especially in the rising organic food markets. Also, many restaurants are now providing vegetarian options to better suit those who do not eat meat. Making the change can be difficult, but persistence in becoming a vegetarian can lead to a more eco-friendly lifestyle
