Genetically modified grass could be the key to reducing cow emissions.
While many cattle are stuffed full of grain, grass-fed cattle have been heralded as a greener way to get beef because it diminishes the need to feed the animals antibiotics and has a smaller carbon footprint, not to mention that it yields beef with less saturated fat. Those of us lucky (or wealthy) enough to feast on grass-fed beef can rest easy knowing we have taken a step toward protecting planet Earth—or so we thought. It turns out there’s a hitch: Cow burps, which send methane into the atmosphere, may increase global warming.
