Our Broken Planet: How to heal our rainforests

Breathe in. Breathe out. The oxygen flowing through your body is the result of photosynthesis: the natural process through which living things convert sunlight into energy. About 30% of land-based photosynthesis happens in tropical rainforests. Rainforests are also great at sucking up excess carbon from the atmosphere – something we know we’ve got to do more of.

But in recent years, rainforests have been getting constricted: shrinking in size and choked up with smoke.

Listen to this podcast from the National History Museum to find out what’s going on and how we can help rainforests breathe deeply again.

Maya Lin: The Quiet Power of Design

When Maya Lin was just twenty-one, her quiet vision changed how a nation remembers. As an undergraduate at Yale, she submitted a class project to a national design competition. It was for a memorial for Vietnam War veterans. Her entry, a sleek wedge of polished black granite etched with the names of more than 58,000 fallen soldiers, was unlike anything the public had seen. Its simplicity sparked debate, but what some called too stark soon became one of America’s most intense and healing monuments.

Lin grew up in Athens, Ohio, surrounded by creativity and intellect. Her mother, a poet, and her father, a ceramic artist and art school dean, taught her to think across disciplines which became the foundation of her career. She often says her work lives “between boundaries – science and art, art and architecture, East and West.” That in-between space is where her designs find their quiet power, inviting reflection rather than demanding it.

Dr. Justina Ray: Listening to the Land

Dr. Justina Ray is not only protecting Canada’s wild spaces – she is about redefining how conservation itself is done. As President and Senior Scientist of Wildlife Conservation Society Canada, she has built a career that reaches far beyond field biology, asking what it truly means to sustain life across landscapes that shape both ecology and identity. Her work has taken her to the tropical forests of Asia and Africa, the vast boreal and sub-arctic zones of Canada, and many places in-between guided by a singular conviction: science must serve the future of the living world.

Ray’s path into northern conservation began with questions rather than assumptions. How do wolverines and caribou survive when their ranges fragment? What happens when the climate itself becomes a moving target? These inquiries led her into some of Canada’s most remote ecosystems, where she has spent decades studying the intricate dynamics of large mammals and their habitats. During her tenure, WCS Canada has transformed such research into a blueprint for better land-use decisions.

Protecting Earth’s Lungs

Forests act as the planet’s terrestrial lungs. They provide us with fresh air, clean water, beautiful vistas and a sanctuary for countless wildlife.

But, today, more than ever, our forests are facing unprecedented threats from disease, climate change, mad-made destruction and harmful pests.

Join this documentary as it follows a group of professionals that developed, tested and formulated today’s forest health strategies to preserve the legacy of one of the planet’s most important resources – and to help us better understand and appreciate why we need to protect our forests.

This is a story that affects us all.

Reforesting the Planet, Restoring the Future

The preservation of the planet’s biodiversity relies entirely on how we manage and interact with the world’s forests.

Reforestation is a critical strategy for mitigating climate change because it increases the Earth’s capacity to absorb carbon dioxide (CO₂)—the main greenhouse gas driving global warming—while also enhancing ecosystem resilience.
In particular, we look at recent studies investigating the most cost-effective approaches to reforestation and the mitigation of climate change. For many years, forest managers have been asking which is best: allowing forests to naturally regenerate, on the one hand, or to plant new forests?
