Women's personal care can also be green. A single woman may use as many as 16,800 tampons in her lifetime and 2,190 disposable pads in just a year alone. And the Ocean Conservancy found almost 20,000 tampon applicators underwater and along shorelines in a 2006 world-wide clean-up. Try using biodegradable or organic products that are free of any chemicals or synthetics. You can also buy washable and reusable female protection products.
