TROPICANA: a division of PepsiCo, has partnered with Cool Earth, an international trust dedicated to protecting the rainforest in a cause marketing campaign. Through 2009, specially marked packages of Tropicana Pure Premiumand Trop50 products will carry a code that consumers can enter online. For each code entered, 100 square feet of rainforest will be saved. Once registered, consumers can enter additional codes with each purchase and increase the area of rainforest they have rescued. Participants can go to Google Maps, register and watch the area of rainforest being saved by Cool Earth grow.
