Environmentalists stress the need for the general public to understand the connection between land use and the environment. The United Nations has declared that raising animals for food is one of the primary contributors to the most serious problems with the environment, from local to global.
Consuming a primarily vegetarian diet would not only have considerable health benefits for the US population, but it would also reduce the amount of greenhouse gas emissions. Experts believe that a meat-eater’s diet is responsible for up to seven times as much greenhouse gas as a vegetarian diet. Meat is a very carbon-intensive commodity.
3,370 square meters are used to produce enough food to feed a meat eater, while only 890 square meters are necessary for a vegetarian. Of the 3370 square meters used for the carnivore, up to 2,950 of those are for animal farming, i.e., sheep, cows, pigs, chickens.
Large nitrogen and fertilizer inputs are necessary for a meat-based diet, resulting in higher CO2 levels.
Experts posit that over twice as much of the recommended amount of protein is consumed in the US every day. In addition to causing health issues, the rate of consumption taxes the environment greatly.
If the American diet evolves from a meat-based to a plant-based one, and consumers make healthy choices, then nutrient inputs, greenhouse gas emissions could all be reduced significantly.
