If you do just one thing, never, ever flush conventional dental floss down the toilet. Not only is nylon dental floss non-biodegradable and a nightmare if it reaches our waterways, it can also destroy plumbing. When floss goes down the toilet, it can twist and wrap around things like hair, toilet paper and other organic matter that goes through the pipes. These clumps can cause dams, which build up over time and create havoc not only in your home's plumbing, but also in public sewage systems. While it may seem crazy to think your own piece of floss can do this, multiply it by the number of people in your community and you can understand the gravity of this one action.
