goats

At the Mountain View, CA headquarters of Google, goats have been employed as a low-carbon alternative to gasoline lawnmowers. About 200 goats are used for a week at a time to trim weeds, eat grass, and clean up brush. They also fertilize as they consume.

A border collie named Jen keeps the goats in a manageable herd. They were rented from California Grazing, a company which has 800 goats for rent (also known as weed abaters).  If you need any goats in the Bay Area, operators are now standing by.
