As a doctor, I focus on removing meat and dairy products from the diet for disease prevention, but many folks choose to eschew meat to reduce their carbon footprint. Just as we can no longer ignore food’s impact on our own health, we can’t ignore food's role in climate change either.
For your eco-conscious friends who still chow down on cheeseburgers, there’s a new documentary emphasizing the meat industry’s global environmental impact. Cowspiracy slams home the fact that meat production is the number-one source of greenhouse gases and deforestation. And while parts of the United States are facing a drought, it takes 660 gallons of water to produce a single hamburger.
Al Gore, Bill Gates, and James Cameron have all been decidedly outspoken about how meat production and consumption affect both health and the environment. Research shows that animal products are bad for humans—leading to an increased risk of heart disease, cancer, obesity, and diabetes. Moving meat products off your plate—for whatever reason— will have a lasting impact on your own health and the environment.
