Earth Focus: The Truth Behind Everyday Chemicals

Unsafe: The Truth Behind Everyday Chemicals

There are tens of thousands of chemicals in our air, water, and in the everyday products we use. They are largely unregulated and few are adequately tested for safety. They contribute to disease and are linked to conditions such as asthma, autism, ADHD, diabetes, cancers, infertility, cognitive disorders, obesity, reproductive disorders and birth defects. "Earth Focus" looks at endocrine disruptors, ubiquitous chemicals that affect development, metabolism, fertility and intelligence at extremely low doses and at what measures could be taken to better ensure public safety.

Fueling Change: Oil Extraction in Alaska and California

The global demand for oil and gas has long-lasting impacts on the communities that supply it. In Alaska’s Arctic National Wildlife Refuge, powerful native communities are at odds over an oil exploration and drilling plan that will boost their economy but have long-term consequences on native species and their environment. In California’s Kern County, the mayors of two neighboring towns face off on the economic benefits and health risks of oil production and their vastly different visions for the most sustainable path to the future.

Lighting A Path: Embracing Solar Power In California and Zanzibar

Solar power is changing lives in unexpected places. At the Barefoot College in Zanzibar, Muslim women who have traditionally been marginalized in the workforce are learning solar installation and bringing it back to their villages, which are primarily powered by candles and paraffin lamps. In East Los Angeles, formerly incarcerated individuals are finding green job opportunities as they transition underserved communities into solar power.

Neonicotinoids: The New DDT?

Neonicotinoids are the most widely used insecticides in the world. But they've been linked to the decline of honeybees, which pollinate many food crops. And scientists now say neonicotinoids also harm many terrestrial, aquatic, and marine invertebrates. These pervasive insecticides damage sea urchin DNA, suppress the immune systems of crabs, and affect the tunneling and reproductive behavior of earthworms. They kill off insects that many birds, amphibians, and reptiles rely on for food.

Dying Oceans: Abalone Restoration In California

The ocean is a sponge for all the greenhouse gas emissions we produce, and entire aquatic ecosystems are beginning to collapse. Off the coast of California, the disappearing abalone population is raising flags about ocean health and the lasting impact of rising sea temperatures, acidification and pollution. Various teams of scientists, volunteers and businesspeople are collaborating to protect underwater species threatened by the invasion of sea urchins.

Building A Future: Lumber Poaching In Oregon and Brazil

Wood is found in countless products consumers use every day. In fact, lumber is closely connected to the world’s economy – a country’ s importation of lumber tends to rise in correlation with its gross domestic product. Following groups like “Guardians of the Forest,” we explore illegal lumber poaching in the forests of Brazil and Oregon, where citizens and scientists are working together to combat the illegal lumber trade.

Climate Change: The Rising Cost

(Earth Focus: Episode 70) The cost of climate change is rising and its consequences are increasingly threatening our national security. Droughts, floods, wildfires, and severe weather cost lives and livelihoods when they damage property, crops, and infrastructure. Communities in Texas, Iowa, Colorado, Alaska are already struggling with the impact of climate change and coastal cities face expensive consequences within a couple of decades. The high price we are paying today is a harbinger of what the future may hold. How will the US economy and national security be affected?

Can Religion Save The Environment?

Led by Buddhist monks, Cambodia's indigenous Chong people protest the construction of a hydroelectric dam. The dam, to be built by the Chinese company Sinohydro, would displace the Chong and destroy their ancestral forest home. Kalyanne Mam documents their plight in her film "Fight For Areng Valley." China is beginning to draw on its religious traditions — Tibetan Buddhism, Daoism and Confucianism — to help address serious environmental challenges as profiled in Gary Marcuse and Shi Lihong's film "Searching for Sacred Mountain."

Tortoise In Peril

Desert tortoises are a threatened species. Habitat destruction, diseases and other factors have reduced their numbers by up to 90 percent. Now flocks of ravens, that often live off human trash, are eating baby tortoises, reducing the odds of tortoise survival as a species. This documentary explores that impact, pointing out how people can change the environment through seemingly innocent actions.
