America’s Dirty Secret: Coal Ash

In Juliette, Georgia radioactive water flows from the tap. In Pennsylvania, three adjoining counties battle a rare form of cancer. One thing these communities have in common is their exposure coal ash. Coal combustion powers 40 percent of America’s electricity but generates 130 million tons of coal ash each year. Though it is known to contain carcinogens, coal ash is often dumped in unlined ponds where it leaches into groundwater. There is no federal coal ash regulation on the books—only a patchwork of state level standards. But people who live near the coal ash dumps in Georgia and Pennsylvania say they are shrugged off as collateral damage by corporate interests and slow moving government agencies. An original "Earth Focus" investigation.

Illicit Ivory

Every twenty minutes an elephant is killed to feed an insatiable demand for ivory. African elephants may be gone in as little as ten years. Behind the slaughter are the most dangerous groups in the world – organized crime syndicates, insurgents and terrorists. Ivory buys guns and ammunition for Uganda's Lord’s Resistance Army and Sudan's Janjaweed, both linked to mass atrocities and supports al Shabaab, the al Qaeda affiliate behind the attacks on Kenya’s Westgate Mall and Garissa University.

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.

Killing Bees: Are Government & Industry Responsible?

Honey bees, the essential pollinators of many major U.S. crops, have been dying off in massive numbers since 2006. This threatens the American agricultural system and the one in 12 jobs that depends on it. There is growing evidence that a new class of pesticides -- nerve toxins called neonicotinoids, which are used on many U.S. crops like corn -- may be toxic to bees.

Sea Level Rising: Living With Water

Louisiana still is learning from Hurricane Katrina. Forecasts are dire for Louisiana to experience the second-highest sea level rise in the world. There is a big movement brewing in New Orleans to build adaptive "resilience zones." In Southeast Louisiana, the native peoples of the Isle de Jean Charles have become the first U.S citizens moving within their homeland displaced by climate change.

Climate Migration

Populations are dramatically shifting as climate change drives migration. Droughts and floods are driving many people away from their rural, farming communities into big cities. We see how this is manifesting in Mongolia and examine the factors leading to the new community of Haitian people living in limbo at the border between Mexico and the U.S.
