CARTER D AMBASSADOR

BACKSTREET BOYS star NICK CARTER has signed up to become the latest celebrity United Nations Special Ambassador. The pop star admits Bono and Nicole Kidman have inspired him to put his celebrity to good use. He says, "I have the advantage of reaching multiple generations to make a difference." But Carter won't be spearheading a crusade for the world's troubled humans - he'll be behind a new environmental push for sea creatures. The singer will represent the United Nations Environment Programme, the Convention on Migratory Species, and the Whale and Dolphin Conservation Society. Carter adds, "I am really excited, but also a little nervous about this much responsibility. "There are responsibilities and commitments that I must make to be the voice of dolphins, whales and conservation issues, and the expectations are quite large."
