After first publishing this news last week, thousands of people have read this article on the Internet and dozens have written to me asking that I offer more evidence of the claim.
I appreciate the feedback, and so I have collected some more facts about cattle pollution from a number of sources on the web.
- Global meat production is projected to more than double from 229 million tons in 1999/2001 to 465 million tons in 2050, while milk output is set to climb from 580 to 1043 million tons. [source: United Nations report, Dec., 2006]
- When emissions from land use (such as production of feedcrops and grazing land) and land use change are included, the livestock sector accounts for 9% of CO2 deriving from human-related activities, but produces a much larger share of even more harmful greenhouse gases. It generates 65% of human-related nitrous oxide, which has 296 times the Global Warming Potential (GWP) of CO2. Most of this comes from manure. [United Nations, Dec 2006]
- Animal agriculture produces...37 percent of the methane [in the atmosphere] annually. [NewsTarget]
- Waste from farm animals in the United States alone is 130 times greater compared to humans. Agricultural runoff [containing animal feces and urine] has killed millions of fish, and is the main reason why 60% of America's rivers and streams are 'impaired'. - [source]
Heard enough? I have. I'm just going to eat less meat and make sure it comes from an organic, cattle-friendly farm, which can be found all over Santa Cruz County, California, and increasingly, the nation.
