Methane gases from livestock production is contributing to the acceleration of global warming. Is a plant-based diet a smart way for individuals to curb the effects of climate change?
Make all the jokes you want, says Bill Nye, but methane is a very potent greenhouse gas, and as Earth's population increases so too does the size of the meat industry that caters to it. Demand for meat is growing steeply in developing nations, according to the Heinrich Böll Foundation, and the methane emitted by livestock is undoubtedly contributing atmospheric gases and accelerating global warming. So is a plant-based diet the answer, slashing the demand placed on the meat and dairy industries? Nye finds himself choosing to eat more and more vegetarian dishes, so while he hasn't gone 'full vegan' yet, his awareness of the problem has sparked a reductionist diet. Nye also mentions that agricultural scientists may soon find themselves under public pressure to reduce methane output. One way they might do that? Changing the bacteria in livestock's stomachs so they metabolize food with less methane byproduct. So we could bio-engineer the stomachs of other animals, or we could simply reduce the amount of animal products that go into our own.
