The U.S. Postal Service recently unveiled its new line of "Go Green" Forever stamps that show simple actions anyone can take to improve the environment.

The 16 stamps feature people of all ages carrying out low-cost or free actions that have an immediate effect on the environment, from adjusting the thermostat and using public transportation to composting and recycling. Designed by San Francisco artist Eli Noyes, the "Go Green" stamps are the Postal Service's social awareness issue for 2011.

  

The stamps are also made from materials that are biodegradable and recyclable, according to Postmaster General Patrick Donahoe.

  

"With these 'Go Green' stamps, the Postal Service is reminding us of the important steps we can take each day to have an impact on the world around us," said U.S. EPA Administrator Lisa P. Jackson. "These stamps demonstrate individual actions - from saving energy or water to reducing waste - that add up to a big difference for our health and our environment."

  

Like other Forever stamps, the new stamps will always be equal in value to the current First-Class Mail one-ounce rate. "Go Green" stamps can be ordered online at usps.com/green and can be viewed "in action" in an animated video.
