Supersizing Climate Change: U.N. Says Meat Production Destroys Land & Diminishes Key Water Sources

The United Nations' top panel of climate scientists warns that humans are consuming land and water resources at an unprecedented rate, with the destructive effects of the climate crisis increasingly threatening the planet's biodiversity and the food security of hundreds of millions of people. In its latest climate change and land special report, the Intergovernmental Panel on Climate Change warns that without dramatic action, extreme weather and rising temperatures will turn even more fertile land into desert, shrinking the global food supply, even as the world's population rises to more than 7.5 billion people. The IPCC recommends dramatic reductions in greenhouse gas emissions, along with more efficient farming methods and a shift in diets away from dairy and meat - which produce vast amounts of methane and carbon dioxide while using large amounts of land. We speak with Pamela McElwee, an associate professor in the Department of Human Ecology at the School of Environmental and Biological Sciences at Rutgers University and co-author of the IPCC report.
