Includes 2 programs. Program 1: Cosmic Alchemy (60 min.) In the beginning, the universe started as a single point. Yet from this tiny beginning came all the matter that we can see around us today. How could pure energy become matter? Over the last century, a series of discoveries have shed light on our understanding of matter.

Program Five: Black Holes and Beyond

Little on this earth can withstand the violent fury of an F5 tornado. A churning vortex with winds over 300 miles an hour, these tornadoes create immense swaths of death and destruction in a matter of seconds. But today, experts are exploring the supertwister's complex inner working in bold new ways in the hopes of one day being able to accurately predict the occurrences of tornadoes.

Examines one of the most revolutionary theories in physics today - String Theory. String Theory argues that fundamental elements of nature are minute strands of energy, whose different levels of vibration underlie everything in the universe. If this theory is correct, it could mean a universe with many different dimensions, ones that are unseen to our eyes.

In 2009, filmmaker Josh Fox learned his home in the Delaware River Basin was on top of the Marcellus Shale, a rock formation containing natural gas that stretches across New York, Pennsylvania and huge stretches of the Northeast.

Is access to clean drinking water a basic human right, or a commodity that should be bought and sold like any other article of commerce? Stephanie Soechtig's debut feature is an unflinching examination of the big business of bottled water.

A huge bottled-water industry has recently emerged, with the U.S. its largest consumer. But is bottled water actually healthier, safer, or tastier than tap water? A water expert explains that bottled water does not meet the same strict standards in the U.S. as water from the tap, though tap-water quality can vary among communities.

Despite its wonders, Earth's water cycle does not spread water evenly around the planet. The Ogallala Aquifer’s huge underground reservoir of water gives the relatively dry Central Plains states such as Nebraska a large but limited irrigation source. But the aquifer's water is being used up faster than it is beng replenished.

From the stunning creators of Blue Planet: Seas of Life comes this epic 5-disc series celebrating the Earth as never before. With an unprecedented production budget, using high definition photography and revolutionary high-speed cameras.

Documentary film that looks at the way modern food is produced through genetic modification and through organic farming in Canada, Europe, India, and United States. A gourmet chef, John Bishop, leads us on an investigation of various genetically modified food products and the leader in genetic engineering, Monsanto

"We can choose to live on a depleted planet or we can choose to live on a rich, biologically diverse, more stable planet' proposes Dr. Mathis Wackernagel, co-creator of the Ecological Footprint. He suggests that an essential step in avoiding depletion is to track ecological assets, allowing us to make more informed choices.

A documentary without narration that explores how water and the ownership and control of water figure into community resistance to corporations rapidly buying up local water supplies. Examines the environmental and human rights issues associated with governments and companies making the world's fresh water supply into a commodity at the expense of local communities.

Contains footage of the wreckage of two famous ships describing the skills and techniques used in underwater forensics.

Our appetite for the earth's resources and consumer goods has led to increased levels of carbon dioxide entering our atmosphere, trapping more heat from the sun and leading to global warming of the atmosphere.

Getting outdoors is one of the great pleasures in life. But our expeditions into natural environments can also cause real horror stories to unfold. Discarded rubbish causes the waterways to become clogged, a campfire can leave a nasty visual scar that can last for years. How can we avoid causing these problems? This program examines ways to minimise our impact when enjoying the outdoors.
