Did you know that it takes 26 bottles of water to produce the plastic container for a one-liter bottle of water, and that doing so pollutes 25 liters of groundwater? Don’t leave a trail of plastic water bottles in your wake! Stop buying bottled water. Use reusable water bottles instead made from materials like stainless steel or aluminum that are not likely to degrade over time. If you choose a plastic water bottle, check the number on the bottom first: Plastics numbered 3, 6 and 7 could pose a health threat to you, so look for plastics numbered 1, 2, 4 or 5.
