It is estimated that Americans toss almost 38 billion water bottles in the trash every year. To combat this environental waste, Brita and Nalgene teamed up to create the FilterForGood campaign.

Gauging it's success by the number of disposable water bottles saved from ending up in a landfill, the program requires participants to pledge to reduce bottled water waste by using a reusable water bottle (Nalgene, encouraged) or filtered water (this is where Brita's pitchers and faucet mount filters come in.)

I'm so excited about this campaign I signed the pledge and am in the process of making sure everyone in the office has a reusable water bottle. You can get involved by taking the pledge and joining the cause on Razoo today.

To see how many water bottles have been saved, you can view a really cool interactive map on the campaign Web site. So go on, take the pledge, help the planet and enjoy a greener, healthier earth.

Happy Earth Day!
