Online ad broker Google Inc. has invested in some old school technology in the name of going greener.

The company’s Mountain View, Calif., headquarters boasts a swath offields that require occasional mowing, for safety and aestheticreasons. This year, the company has opted to hire goats rather thanlandscapers to provide the service.

“A herder brings about 200 goats and they spend roughly a week withus at Google, eating the grass and fertilizing at the same time,”writes Dan Hoffman, director of real estate and workplace services, on Google’s blog.“The goats are herded with the help of Jen, a border collie. It costsus about the same as mowing, and goats are a lot cuter to watch thanlawn mowers.”

The Onion has posted an interview with a goat.
