The days of carbon emitting weed-wackers and lawn mowers may soon be coming to an end thanks to the renaissance of an ancient technology. Goats. Google, Amazon and even the Congressional Cemetery in Washington D.C. have implemented goats at their facilities and you can too.
While goats will eat grass, they really excel at brush clearing, removing unwanted plants and turning into natural fertilizers. You can make socks out of their shedding wool too. How cool is that?
