Farmers Are Using Garlicky Supplements to Curb a Major Environmental Enemy

While passing gas is considered a simple social faux pas, cow burps are notorious for producing more than a foul smell — they produce a gas that’s terrible for the environment. Thankfully, a new garlic-based dietary supplement is being given to cows to reduce the methane content in cow belches by 30%, which could help reduce greenhouse gas produced from cattle ranching. Studies have shown no adverse affects in both the health of the cows and the flavor of their milk and meat. If every cow in America and all 30 million horses could be given the supplement, the reduction in the methane they produce could result in making animal methane emissions a little over 1% of total greenhouse gas.
