Supermodel Gisele Bündchen and actor Don Cheadle are teaming up to help promote The United Nations Environment Program's World Environment Day on June 5, 2011.
World Environment Day's purpose is to promote positive action to help the environment and shows that the power of individual actions is exponential when combined with others.
Individuals, groups, and schools can organize environmental activities and post the details of their planned green events on the World Environment Day website. When they do, they will be asked to pledge their event to either Bündchen or Cheadle. For every pledge that Bündchen receives, she will plant one tree. For every event that is pledged in Cheadle's name, he will plant two trees.
