The Nature Conservancy

Nature Conservancy/Laura Stoecker

Our mission is to conserve the lands and waters on which all life depends.

Our vision is a world where the diversity of life thrives, and people act to conserve nature for its own sake and its ability to fulfill our needs and enrich our lives.

Today, the world is facing environmental challenges unlike any we’ve seen before. The population is expected to reach nine billion by 2050, putting tremendous pressure on the natural resources we all depend on for food, water and clean air. A changing climate is causing heat waves, extreme droughts and catastrophic flooding. Habitat loss threatens our forests, prairies and wetlands, as well as the wildlife that rely on them for survival. And our rapidly-growing urban areas are disconnected from nature, making them more prone to air pollution, sewer overflow, urban heat islands and loss of native species.

The biggest question of our time is this: Can people and nature thrive together? At The Nature Conservancy (TNC), we know the answer is yes. We have used our science to rigorously examine this question, and it shows us there is another way forward. We can create a new vision for the planet—one powered by a virtuous cycle, where we take care of nature so that nature can take care of us.

Utilizing more than 60 years of experience, TNC has developed a plan that will help put our world on a brighter, more sustainable path. Working right here in the Prairie State, TNC is protecting our lands and waters at places like Emiquon, our floodplain restoration along the Illinois River. We are collaborating with the state’s agricultural community to provide food and water in ways that are both sustainable and profitable. We are working to make our cities more resilient. And we are leveraging our strong science and diverse partnerships with government agencies, businesses and other nonprofit organizations to tackle climate change.

How to Help
A donation of any size will help advance our important conservation initiatives. TNC has a range of programs that facilitate the donation of real estate, land or stock for both individuals and family foundations, and our Legacy Club allows those who are interested to include TNC in estate planning. You can also support our work through corporate giving or by becoming a member of TNC. For more information, contact Ken Modzelewski at
