Pruney Fingers: A Gripping Story

Why do fingers become pruney when they get wet? Likely, for the same reasons that tires have treads. Mark Changizi examines the evolutionary reasons for pruney fingers, while exploring natural and manmade phenomena, like river networks, that operate similarly.

Fracking Hell: The Untold Story

An original investigative report by Earth Focus and UK's Ecologist Film Unit looks at the risks of natural gas development in the Marcellus Shale. From toxic chemicals in drinking water to unregulated interstate dumping of potentially radioactive waste that experts fear can contaminate water supplies in major population centers including New York City, are the health consequences worth the economic gains?

Marcellus Shale contains enough natural gas to supply all US gas needs for 14 years. But as gas drilling takes place, using a process called hydraulic fracturing or "fracking," toxic chemicals and methane gas seep into drinking water. Now experts fear that unacceptable levels of radioactive Radium 226 in gas development waste.

Fracking chemicals are linked to bone, liver and breast cancers, gastrointestinal, circulatory, respiratory, developmental as well as brain and nervous system disorders. Such chemicals are present in frack waste and may find their way into drinking water and air.

Waste from Pennsylvania gas wells -- waste that may also contain unacceptable levels of radium -- is routinely dumped across state lines into landfills in New York, Ohio and West Virginia. New York does not require testing waste for radioactivity prior to dumping or treatment. So drill cuttings from Pennsylvania have been dumped in New York's Chemung and other counties and liquid waste is shipped to treatment plants in Auburn and Watertown New York. How radioactive is this waste? Experts are calling are for testing to find out.
New York State may have been the first state in the nation to put a temporary hold on fracking pending a safety review, but it allows other states to dump toxic frack waste within its boundaries.

With a gas production boom underway in the Marcellus Shale and plans for some 400,000 wells in the coming decades, the cumulative impact of dumping potential lethal waste without adequate oversight is a catastrophe waiting to happen. And now U.S. companies are exporting fracking to Europe.
