Simply put, reusable water bottles are good for the environment in all the ways that plastic water bottles are not. A reusable water bottle takes less oil to produce, replaces all the plastics that you would have used and thereby reduces both your carbon footprint and helps reduce the plastic burden on landfills, oceans, streams and other places that plastic waste ends up. Switching to reusable water bottles is a great way to do your part to help limit the plastic pollution crisis, especially if you are in the habit of carrying beverages with you. The temptation to use a plastic bottle, or to purchase a drink in a plastic container can be hard – they are seductively convenient! But once you know just how much making the switch matters, it might become easier.
