Instead of traditional gift giving this holiday season, consider adopting an endangered animal through the World Wildlife Fund's species adoption. With donations ranging from $25 - $250 you can help support and protect severely endangered animals. There are over 100 species to choose from and you can even sort by threat level (extinct in the wild, critically endangered, vulnerable etc.).
"Your donation will be used in general support of WWF's efforts around the world. 82 cents of every donated dollar goes toward conservation. WWF has been recognized by Charity Navigator as a Four Star Charity, and is a Better Business Bureau Accredited charity.World Wildlife Fund is a 501(c)(3) charitable organization."
