Air, water, food, shelter, income: nature sustains every aspect of our lives. That's why protecting and conserving nature isn't just a matter of common sense. It's the smartest investment we can make. Since our founding in 1951, The Nature Conservancy has harnessed the power of nature to help solve our planet’s most challenging problems. And while the stakes are high, so is our resolve: to create a world where everyone thrives alongside nature for generations to come. We do this by working hand in hand with communities around the world. By committing to a science-based, non-partisan approach that’s stood the test of time. And by bringing people together, from all walks of life, to find common ground in nature.

As America's largest non-profit conservation organization, the National Wildlife Federation works closely with those who span the social and political spectrum, but who are connected by a common commitment to conservation. Our ability to meet the needs of wildlife is inextricably linked to the over 6 million amazing individuals, groups, organizations and corporations we call our supporters. Our mission is to unite all Americans to ensure wildlife thrive in a rapidly changing world. Through conservation efforts, grassroots actions, education programs, and award-winning publications (including National Wildlife, Ranger Rick, and Ranger Rick Jr.) we connect with people across the nation to safeguard America’s wildlife and wild places.

Founded in 1972, the nonprofit Arbor Day Foundation is a million-member conservation and education organization with a mission of inspiring people to plant, nurture, and celebrate trees. More information about the Foundation's programs and impact are at www.arborday.org.
