It's not just that glaciers are melting, it's the fact that animals and plants that live in a specific climate can easily perish in the change in that specific climate. It's also destroying habitats, and it's thinning out our atmosphere/ozone layer and that will kill us if we don't take a stand and stop polluting our world. We only get one you know. But I'm glad at least you're doing good for the planet without even realizing it. But you still need to at least take a minute to realize the full danger that could happen if we don't do something about it.
