The environmental cost of bottled water is incredibly high. Imagine, simple water pouring out of a glacier. It have to be collected (by some powered device), tested, and bottled. The bottles are made of everyone's favorite, plastic. Then it has to be distributed, either by ship, air, or road, all over the country and world. It's placed on shelves where it is bought and taken far and wide. Once the water is done, most of the bottles are simple garbage. For a quick swig of water. It truly is a crazy thing. Most of the cost of a bottle of water is getting the water into your hands, because the water itself is likely near "free".
