A new study shows that the environmental impact of beef is 10 times that of chicken and pork. In the United States research team led by Gudrun Essall, professor of environmental science at Bard College, the land nutrients were estimated to improve different types of products.
The results of the study indicate that beef production requires more than 28 times more land and 11 times more irrigation water than pork or chicken. At the same time, greenhouse gases are emitted five times as much. Although it is known that beef production has a considerable impact on the environment, this quantitative analysis can have a clearer understanding. Lamb and fish consumption in the United States is relatively low and studies have not been conducted. The huge environmental impact of beef is because cattle are far less efficient in converting food than pigs and chickens. “A very small portion of the food consumed by cattle enters the bloodstream, and most of the energy is lost,†Eshar said, and if food is used instead of grass feeding cows, this will make the efficiency even worse.
Although research does not mean that you must give up your favorite steak, it does provide an effective way to reduce carbon emissions as long as you eat less. “The biggest human intervention is not to give up cars, but to reduce beef consumption,†said Tim Benton of the University of Leeds in the United Kingdom. The Australian Department of Health recommends daily intake of 65 grams of cooked beef, that is, 90 to 100 grams of raw meat. Reducing your intake will not only thank you for the environment, it will also significantly reduce the risk of bowel and stomach-related cancers.
