21 trees sucking on things

Volunteer. Whether you choose to do trail maintenance in Costa Rica or rebuild indigenous rainforest communities in Canada, you can volunteer to save the rainforest. Through a number of organizations, you put your blood, sweat, and tears (plus some of your money) into important conservation efforts.

• Organizations such as United Planet, Environmental Quest, Goabroad.com, and others can help you select the volunteer opportunity that is right for you.
