Global-warming debate shouldn’t exclude role of livestock
Regardless of what the actual total of livestock contribution to global warming, it is part of the problem and we ignore it at our collective peril.
The struggle to halt global warming ordinarily focuses on fossil fuel consumption and use, currently exemplified by the Alberta tar sands and the proposed Keystone XL pipeline to the Gulf of Mexico. It would be foolish to disregard that, but what if the rapidly expanding livestock industry has been overlooked as a major contributor to global warming?
A paper published in World Watch that provides a strong argument that animal agriculture is significantly undercounted as a contributor to global warming. What makes this study interesting is that, in contrast to unsupported claims about methane sometimes made by vegan and animal-rights activists, it grounds its arguments squarely on carbon dioxide.
The World Watch paper, authored by environmental scientists Robert Goodland and Jeff Anhang, concludes that livestock contributes 51 percent of annual greenhouse-gas emissions, and provocatively advocates substituting meat and dairy products with analogs as the fastest way to avoid the planet reaching a climatic tipping point. The paper argues that there is not enough time, nor sufficient political will, to make necessary changes in energy and transportation before irreversible climate changes are upon us.
The sources, and thus the solutions, to global warming constitute a legitimate debate.
