Yes indeed, some 60 percent of our household indoor water usage happens in the bathroom. As such, updating old leaky fixtures and changing a few basic habits could go a long way to not only saving fresh water, an increasingly precious resource, but also money.

As many as four out of five U.S. households already take the time to separate recyclables from trash. Those holdouts not yet willing to bother should consider the benefits to their household and society at large.
