Here are only a few facts from the November 2006 UN Food and Agriculture Organization report called Livestock’s Long Shadow:
- Livestock production is one of the top two or three most significant contributors to every serious environmental problem in our world today.
- Livestock production requires 70% of all agricultural land and 30% of the land surface of the earth.
- As a result, many people, particularly in the so-called third world countries, no longer find land to grow their own crops. The result is hunger and for many, starvation.
- Livestock production is one of the main causes for the extinction of species. In 15 out of 24 important ecosystems, livestock is named as the major culprit for their decline.
- The expansion of livestock production is a key factor in the deforestation of rain forests, particularly in Latin America: some 70% of previously forested land in the Amazon basin is used for pasture, and feed crops cover a large part of the remainder. Forests serve as the lungs of the Earth and are a major factor in eliminating the greenhouse gases from the atmosphere.
- The production of greenhouse gases of human origin, that are generated by livestock production is higher than EMISSIONS CAUSED BY ALL WORLDWIDE MEANS OF TRANSPORTATION.
- The livestock sector is responsible for 18% of all greenhouse gas emissions
- Livestock production generates even larger shares of gas emission with greater potential to warm the atmosphere: 37% of methane and 65% of nitrous oxide
- Livestock production is a significant contributor to the growing lack of water, which researchers predict will be one of our main problems in the future. In many parts of the world, clean drinking water is no longer available:
- Livestock production is the largest source of water pollutants: animal wastes, antibiotics, hormones, chemicals, fertilizers and pesticides for feed crops.
- 8% of the worldwide consumption of water is used for the irrigation of feed crops.
- In the US alone, livestock and feed crop agriculture are responsible for the use of 37% of pesticides, 50% of antibiotics. They are also responsible for 33% of all nitrogen and phosphorus found in freshwater resources, and 66% of all ammonia, which is a significant contributor to acid rain and the acidification of ecosystems.
