The benefits of using cars, tractors and other man made devices are evident all around us. Horses are tempormental and require constant attention. They have to be washed, fed and broken in. So then why do we still domesticate them?
There are still plenty of good reasons why we keep horses around. Police officers use them as a form of crowd control in the city when people get out of hand. Horses are good for pushing a crowd back, while at the same time protecting the police officer. They are also a lot of fun to ride. We keep them around to remind us that we were once dependent on them.
The dumbest reason we keep them around is for racing. I think this is a stupid life for this great animal. But then again, that's my opinion. The next time you meet a horse give him a carrot or a sugar cube, he will thank you for it.
