<P> Since its formation in 1951 The Nature Conservancy has slowly developed into one of the world's largest conservation organizations . Currently operating in over 30 countries, across 5 continents worldwide, The Nature Conservancy aims to protect nature and its assets for future generations . The organization purchases land or accepts land donations with the intension of conserving its natural resources . In 1955 The Nature Conservancy purchased its first 60 - acre plot near the New York / Connecticut border in the United States of America . Today the Conservancy has expanded to protect over 119 million acres of land, 5,000 river miles as well as participating in over 1000 marine protection programs across the globe . Since its beginnings The Nature Conservancy has understood the benefit in taking a scientific approach towards habitat conservation . For the last decade the organization has been using a collaborative, scientific method known as' Conservation by Design' . By collecting and analyzing scientific data The Conservancy is able to holistically approach the protection of various ecosystems . This process determines the habitats that need protection, specific elements that should be conserved as well as monitoring progress so more efficient practices can be developed for the future . </P> <P> The Nature Conservancy currently has a large number of diverse projects in operation . They work with countries around the world to protect forests, river systems, oceans, deserts and grasslands . In all cases the aim is to provide a sustainable environment for both the plant and animal life forms that depend on them as well as all future generations to come . turtles </P> <P> The World Wildlife Fund (WWF) was first formed in after a group of passionate conservationists signed what is now referred to as the Morges Manifesto . WWF is currently operating in over 100 countries across 5 continents with a current listing of over 5 million supporters . One of the first projects of WWF was assisting in the creation of the Charles Darwin Research Foundation which aided in the protection of diverse range of unique species existing on the Galápagos' Islands, Ecuador . It was also a WWF grant that helped with the formation of the College of African Wildlife Management in Tanzania which today focuses on teaching a wide range of protected area management skills in areas such as ecology, range management and law enforcement . The WWF has since gone on to aid in the protection of land in Spain, creating the Coto Doñana National Park in order to conserve migratory birds and The Democratic Republic of Congo, home to the world's largest protected wetlands . The WWF also initiated a debt - for - nature concept which allows the country to put funds normally allocated to paying off national debt, into conservation programs that protect its natural landscapes . Countries currently participating include Madagascar, the first country to participate which since 1989 has generated over $US50 million towards preservation, Bolivia, Costa Rica, Ecuador, Gabon, the Philippines and Zambia . </P> <P> Rare has been in operation since 1973 with current global partners in over 50 countries and offices in the United States of America, Mexico, the Philippines, China and Indonesia . Rare focuses on the human activity that threatens biodiversity and habitats such as overfishing and unsustainable agriculture . By engaging local communities and changing behaviour Rare has been able to launch campaigns to protect areas in most need of conservation . The key aspect of Rare's methodology is their "Pride Campaign's". For example, in the Andes in South America, Rare has incentives to develop watershed protection practices . In the Southeast Asia's "coral triangle" Rare is training fishers in local communities to better manage the areas around the coral reefs in order to lessen human impact . Such programs last for three years with the aim of changing community attitudes so as to conserve fragile habitats and provide ecological protection for years to come . </P>
