At some point in the 20th century, the weed trimmer was invented. It's a motorized weed- and grass-trimming device that uses rapidly revolving strings to cut down vegetation in small spaces without destroying the bark of trees. It's easy to use and doesn't require much in gas or electricity to run. Genius!
Too bad the inventor of the weed trimmer didn't know about goats, though. Because even though he made plenty of money, his invention was extremely redundant considering that we essentially had weed eating in the bag with our first domesticated animal 10,000 years ago.

Of course, using goats as mowers seems like the type of 21st-century innovation that reliably causes your dad to shake his head in mystified silence, like when you ride your bike to work after stopping for a $5 espresso drink. But using goats to maintain vegetation works just as well today as it did in ancient Mesopotamia. Goats are commonly used to control big swaths of land in cemeteries, parks, airports and even Google headquarters, and though they don't cut grass and vegetation down as evenly as a piece of machinery, there are a lot of benefits to using animals rather than machinery and herbicides.
