Nothing is certain except death, taxes, and needing a new toothbrush.

Because you really can't keep the same toothbrush forever, that's gross. Buying a new toothbrush every few months is as predictable as getting an oil change or a haircut. In order to function in polite society, you need all three of those things.

Which is a roundabout way of saying that human beings throw away massive amounts of toothbrushes every year. Plastic takes a long time to biodegrade, and it is already killing off life in the ocean.

So I present to you one of my favorite granola-crunchy companies, Preserve. The company makes several products, but my favorite is the toothbrush, which has a handle made from 100% recycled yogurt cups. Such a simple, elegant thing. Not only is it recycled, but it's recyclable--you can send it back to the company when you're done with it, and they'll recycle it again. Think about all the plastic that cuts down on!

Preserve also does razors, kitchenware and tableware. The products can be found at Target, Whole Foods and other health food stores.
