I choose this charity because they help preserve plants, animals and natural communities all over the world, everyday. In 2007 they accomplished a great deal. They brokered the largest debt-for-nature swap under the Tropical Forest Conservation Act-this deal secures long term science based conservation for Costa Rica's tropical forests. This means that the United States will forgive $26million in debt owed to it by Costa Rica. It will provide funds that will be used to finance forest conservation in Costa Rica. It will provide funds that will be used to finance forest conservation in Costa Rica over the next 16 years. I love stories like this it makes the whole green movement worth while, knowing there are charities like this striving to protect our earth.
