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.
