While plastic water bottles are still in widespread use, they really shouldn’t be. They take a lot of energy to make, and the water in them is probably not much better than the water coming from your faucet. In addition, since plastic doesn’t break down readily in nature, these water bottles cause an environmental problem that will be with us for a long time. With a vacuum insulated water bottle, you don’t need those old plastic water bottles, anyway. While these bottles come in many shapes and sizes, most are shaped somewhat like a soda bottle or plastic water bottle. Once you own one, simply fill it up frequently and you can have enough cold water to keep you well hydrated in even the hottest of weather. And since they are available in many different colors and designs, you can even pick one that makes a fashion statement.
