In celebration of Earth Week, NBC’s Share and Tell Blog App explores the concept of sharing goods with others in an effort to make the world more ecologically and environmentally sound. NBCU has partnered with Yerdle to share your stuff and tell about the experience. This contest will net you some nifty prizes if you are randomly selected as the winner.

To participate, share with us one item that you own that you would consider sharing with others in an effort to reduce your carbon/human imprint on the environment. Your submissions are due no later than Sunday, April 28, 2013. One winner will be selected at random from all entrants on Monday, April 29, 2013 with the winner announced that day or Tuesday, April 30, 2013. You will need to have your mailing address information in no later than Thursday, May 2, 2013. A runner-up will be selected on Monday/Tuesday and they will need to submit their information as well in case the winner doesn’t submit in time.

What could you win? You will win one “Green Is Universal” canvas tote bag (made from recycled cotton) as well as two randomly selected items from the following list: One Planet Ocean DVD; One Green Is Universal T-Shirt (from Alternative Apparel); One Green Is Universal colored pencil kit (made from recycled newspaper); One Green Is Universal Vapur water bottle (BPA-free); One Green Is Universal hardboard cover spiral bound notebook; one Green Is Universal burpal FEED bag.

This contest is operated on behalf of NBC Universal by PartnersHub.

To accompany this contest, here’s a free in-browser app where you can take a quiz and participate in other activities to keep you occupied while you wait for the results.
