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.

“Vanishing Coral” presents the personal story of scientists and naturalists who are working with local communities to protect coral reefs that are being destroyed by warming seas, pollution, and destructive fishing practices.

(Earth Focus: Episode 53) It is possible to rehabilitate large-scale damaged ecosystems, to improve the lives of people trapped in poverty and to sequester carbon naturally. John Liu presents "Hope in a Changing Climate," which showcases approaches that have worked on the Loess Plateau in China, Ethiopia and Rwanda. Produced in collaboration with the Environmental Education Media Project (EEMP).

(Earth Focus: Episode 41) What do plants, snakes, molds, marine sponges, and cone snails have in common? They have helped develop medicines that save human lives. Biodiversity -- the variety of life on Earth -- is key to human survival. But plants, animals, and microorganisms are disappearing at unprecedented rates. What impact will this have on human health? Find out in this Earth Focus special report produced in collaboration with the Center for Health and the Global Environment, Harvard Medical School.

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.

Food and social justice. Human rights abuses, rape and corrupt practices in the Bangladesh shrimp industry. A report by the Swedish Society for Nature Conservation uncovers the human and environmental cost of shrimp farming and shows why buying shrimp from Bangladesh where they are exposed to pesticides and injected with dirty water may be hazardous to your health. UK's The Ecologist investigates the plight of African migrant workers in Italy and looks how financial speculation is threatening the livelihood of Mexican farmers.
