When we think of endangered animals we are thinking of wild animals but did you know some of our own farm animals are endangered? Just looking at horses there are dozens of breeds about to fade out of existence, but there are concerned organizations big and small that are trying to keep the breeds alive. You can read all about these horses on websites such as Rare Breeds Canada and the American Livestock Breeds Conservancy. In Britain you can find information through the Rare Breed Survival Trust.
There are so many unwanted, abandoned horses; many are sent to slaughter. These lists answer the question as to why people are still breeding horses. Someday we may not have these beautiful animals at all and what shame that would be. The horse itself will continue to live in our world but their history will be lost as the breeds are blended.
