Earth Day is Wednesday, April 22. In celebration of our planet's big day, why not take a moment to make a simple green resolution for the coming year? Here's mine: Bike to work at least once a week. Full disclosure: The last time I owned a bike, it was a blue Schwinn with a hot pink basket and I was 10. Sadly, I've outgrown that bike. But now, after months of bugging my friends for bike recommendations and visiting all of the bike shops around town, I've narrowed down my choices and am finally ready to invest in an "adult" bike at last. By this Earth Day, I am determined to be a proud bike owner/commuter/road warrior at least once a week. Why not every day? After years of making (and always breaking) grandiose New Year's resolutions, I've learned that the simple, realistic changes are the ones that really last. Now it's your turn. Tell us one simple green change you're planning to make for Earth Day. Everyone who enters a comment on this post between now and April 30th will be entered to win a $25 Whole Foods Market gift card and a FEED 100 bag. The winner will be announced the first week of May in our Whole Story blog, so stay tuned! And even if you don't win the prizes, your green resolution efforts will be rewarded with a cleaner, greener, healthier planet for many Earth Days to come. Here's to wishing you and yours a Merry Earth Day and a Happy Earth Year! Check out more green ideas on our Whole Story blog. Visit our website for more Earth Month tips, trivia, contests and more.
