The Nature Conservancy is a global organization dedicated to protecting the lands and waters on which the diversity of life depends. We envision a world where forest, grasslands, deserts, rivers and oceans are healthy; where the connection between natural systems and the quality of human life is valued; and where the places that sustain all life endure for future generations. We are one of the world's largest private, non-profit, nongovernmental conservation organizations. Yet we operate at the local level, working in hundreds of communities on the ground to conserve natural diversity and sustain livelihoods.
