EcologyFund is a lesser-known click-to-donate free site that has been active for several years. There are 4 buttons to click every day: South American rainforest, reduce pollution, protect endangered species, US wilderness. It is owned and operated by The Hunger Site Network (who also run www.therainforestsite.com) as a way to get new funds for critical habitat and wilderness preservation using the power of the internet.
