Do you practice sustainable living every day? Get rewarded for your green habits by entering these contests:

>> Win $10,000 by being the greenest Roommate of the Year.’s second annual Roommate of the Year Contest includes an environmentalist category for roommates "who take unique measures to make green living a priority.” If you win the top title, you’ll get $10,000 in cash and a year’s worth of free rent. Almost makes me wish I had a roommate …. Get your entry in by June 14.

>> Win a Breezer Uptown 8 by writing a bike-ku, a.k.a. a haiku inspired by your bike. The Sierra Club is motivating people to get creatively inspired by their bikes. Simply join the nonprofit’s bicycle group on Climate Crossroads, post a photo, then compose a three-line poem. Just make sure to get your entry in by May 31 — the last day of Bike Month!

>> Win a trip to NYC and take part in the largest documented yoga event ever, happening June 22 at 6 p.m. on the Great Lawn in NYC's Central Park. Organizers hope the free yoga class — which is led by Elena Brower and hosted by Flavorpill and JetBlue’s TrueBlue — will make it into the Guinness Book of World Records. For a spot in the class — and a chance to win one of five flight-and-hotel packages if you don’t live in NYC — register at Flavorpill. Get your entry in by June 9. If you’re selected, remember to bring your own bottle and refuse the disposable plastic-wrapped stuff that’ll be given out by one of the sponsors.
