Keep Wildlife in the Wild

I know that we as humans are invading on the natural habitat of certain wildlife species, but if something doesnt happen we are slowely killing off the wildlife near us. Take Banff Canada for example, people there drive down the road not thinking about what they are doing and are slowely killing of the natural species there in the park. This is the same in the city of Banff. The elk there are venturing further and further in to the city. Last year some gentlemen was taking a picture of this so called tame elk, what an idiot. When the elk statrted to charge him and made a shishkabob with him and the elks horn. The park had to kill this elk so he wouldnt do anything like that again. This is a perfect example of people venturing onto a willifes territory. We are visitors there, they are not visitors on our property.
