Just how it's important to preserve rain forests, it's also important to preserve the wild life. Sure you don't want these creatures roaming in the city, but if they are in their natural environment miles away from "civilization" leave them alone. They shouldn't be hunted down in order to be made into expensive coats or other fancy items.

And also we should ensure that pollution doesn't harm these creatures either. This includes the illegal dumping of dangerous chemicals and so on, I've seen various articles that show dead whales on the shore or seals along with other creatures.
