Over a span of nearly 70 years, United States water consumption has jumped 127 percent. Sadly, there is actually less clean water available worldwide. How major of a problem is this? A whopping 10 percent of the total population doesn't have access to clean drinking water. Thankfully, recent initiatives to "save" water and provide more people with better access are picking up in a big way. For example, Colgate recently entered a partnership with The Nature Conservancy, and is working their "Save Water" initiative in no small way.
