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?
The Role of Technology in Forest Management
In Brazil’s Pará region, new roads are cutting through the pristine Amazon rainforest, opening up once-untouched areas to human activities. Expansive stretches of lush greenery are vanishing at an alarming pace, yielding to barren patches and freshly cleared land.
Meanwhile, far into space, the European Space Agency captures high-resolution satellite images of the region that unveil an important pattern: deforestation occurs predominantly near these newly constructed roads.
Back in 2016, it sparked a question: what if there were a tool to monitor these roads and forecast potential deforestation areas? Not long after PrevisIA was born.
In 2021, Microsoft with Vale Fund and the Amazon Institute for Man and the Environment (Imazon) developed a new AI tool called PrevisIA, to predict deforestation hotspots in the Amazon. Using satellite imagery from the European Space Agency and an algorithm developed by Imazon, the tool produces heat maps showing the most exposed conservation areas, Indigenous lands, and other settlements, along with rankings for states and municipalities.
Shrinking Forests, Emerging Diseases
Dona Dora’s man is away from home a lot more these days. It didn’t used to be like that.
He leaves early, sometimes on foot, but increasingly on his bicycle, and heads into the forests surrounding Belém, the capital of Brazil’s Para province. He keeps his eyes open especially for five medicinal plants that are always in demand — sucuúba (Himatanthus sucuuba), copaíba (Copaifera spp.), andiroba (Carapa guianensis), barbatimão (Stryphnodendron spp.) and pãu d’arco (Tabebuia avellanedae).
Fifteen years earlier, he would have found all five within hours and been back for lunch, but times have changed. These days, medicinal forest plants in high demand are becoming harder to find as forests that have stood strong for millennia are cleared to make way for grazing pastures for millions of cattle, agriculture, and development.
Now, Dona Dora’s man can spend a whole day and not find more than a few plants. It might be late at night before he gets back home.
Daniel Beltrá: Capturing Earth’s Beauty and Humanity’s Impact
Daniel Beltrá, a Madrid-born photographer now calling Seattle, Washington, his creative haven; has a distinctive approach to his photography. His most captivating works are large-scale photographs taken from the air, providing viewers with a sweeping panorama of our world’s wonders and woes.
His unwavering passion for conservation can be seen from this elevated vantage point as he skillfully reveals the contrast of nature’s magnificence and humanity’s destructive footprint.
Deforestation 101
Forests cover about 30% of the planet, but deforestation is clearing these essential habitats on a massive scale. What is deforestation? Find out the causes, effects, and solutions to deforestation.
Deforestation’s Hidden Toll: Amplifying Disease Risk Worldwide
In the last couple of decades, the lush rainforest around the remote village of Meliandou in the heart of Guinea has become patchier. Animals, like bats, saw their habitats dwindle and in a quest for survival, they sought refuge in closer proximity to human environments, making the boundaries between species thinner. A hollowed-out tree in the middle of the village became home to a colony of bats.
About 50 meters from the same tree, in the heart of Meliandou, a two-year-old boy named Emile lived with his family. In a matter of days, Emile fell ill with an unknown virus, developed a high fever, and died. Soon the same virus, that scientists now believe Emile got from the bats, took the lives of his sister, mother, and grandmother. The village, surrounded by a ring of forest, unexpectedly became the epicenter of a devastating outbreak that would leave an indelible mark.
Indigenous Peoples’ Role in Protecting Forest Health
Nearly a quarter of the world’s population, or about 1.6 billion people, depend on forest resources to sustain their livelihood. This number includes an estimated 60 million who are members of indigenous groups. The worldviews of most indigenous cultures include a sacred obligation to serve as stewards of a healthy forest that can sustain its inhabitants for generations.
Indigenous peoples have been effectively managing their forests since “time immemorial,” yet governmental and scientific forestry experts have only recently begun to seek out the knowledge that indigenous peoples have about environmental management.
