I don't agree with killing animals just for their fur. leather I'm ok with, because it comes from a cow that is being used. But really, who eats chinchillas and zebras?
I'm a horseback rider, so I have no way of not using leather. I would love to just be able to use synthetic material...but it's not possible.
I can at least get a little comfort in knowing that my leather comes from an animal that is being used for its meat as well.
