Wildlife officers kill bear that claws homeowner"

In the Denver Post the article, “Wildlife officers kill bear that claws homeowner,” was posted. The article talks about how a bear in Snowmass, Colorado got inside a garage and then clawed the homeowner. It was then shot and killed by wildlife officers. Recently, there have been several animal attacks in Colorado. Also posted in the Denver Post the same day was an article about a man shooting a Mountain Lion, after the wild cat attacked his dog and then tried to come towards him. 45 black bears have been shot dead this past year. This makes me think how much of a threat wild animals are to us. Is there really a need for all these animal killings?
