9. Bottled Water
It’s a poor idea to buy water in a bottle. This water is not only more costly than regular tap water. But it’s also not always superior quality. Many bottlers get their water from the same municipal source that provides water to your home.
Making and shipping all those bottles uses a lot of fossil fuel, and tons of plastic are thrown away every year.
Even with the cost of at-home water filters, filling a reusable bottle will save you money and help the environment.
