The first Earth Day in 1970 led to the creation of the United States Environmental Protection Agency and the passage of the Clean Air, Clean Water and Endangered Species acts. We've come a long way in 42 years—green has gone mainstream and Earth Day has become a day to celebrate all things earthy. It's also become a day to celebrate freebies, coupon codes and sweepstakes. Here's a sampling of some of the promotions available.
• In true Earth Day spirit, Alternative Apparel has announced its "Buy a tee, plant a tree" initiative. Until April 22, they will have a tree planted for every item you purchase … in addition to a 20 percent discount.
• Caribou Coffee Company will reward sustainable coffee drinkers by offering free coffee to all customers who bring in a reusable mug on Earth Day.
• Target is giving away one reusable bag per customer on April 22; check at your store's guest service desk.

Happy Earth Day!
