Yes we don't live in the earth but that's not what this is about what this is showing is how little water we have.
Water is the source of all life on our planet and we continue to use it as a dumping ground and poison it with oil spills. So to anyone with an ounce of common sense when they see this fact put into a image like that should think about how we MUST keep it clean and not continue down the route we are currently taking.
