You do your part when it comes to the planet.

Taking ecofriendly taxis. Forgoing the night-light. (How many years of therapy did that take?) And though you may not be ready to ditch the SUV quite yet, hey, at least you’re making an effort.

So next time you drink water, take advice from The Biggest Loser and go green with a Brita Filter and Nalgene 'Filter For Good' water bottle. As you know, the new season of The Biggest Loser has already started and this time people are losing weight in pairs - husbands and wives, best friends, mothers and sons or daughters. Another new thing this season is their ban on bottled water. The Biggest Loser is trying to be more friendly to the planet, and drinking bottled water creates a huge amount of waste. Last year Americans threw out $1 billion worth of plastic.

The good news: You can start reducing waste at home, too. I’ve got three Brita faucet mounts and three reusable Filter For Good bottles that I’m giving away. I’ll randomly pick three of the commenters on this post to receive them - so leave a comment before January 30th and I might pick you.

In the meantime, you can go to the Filter For Good website and do what I did and take a pledge to reduce bottled water waste. And if you don’t win an FFG bottle in my giveaway, you can buy one and the proceeds will go to the Blue Planet Run Foundation, a nonprofit organization working to provide 200 million people with a lifetime’s worth of drinking water by 2027.

Just think: Your new Brita filter and Filter For Good water bottle are sure to spark a conversation. About, say, trading in that SUV for a sleek new hybrid.

You know, for the planet and all.
