The invasive lionfish--venomous and voracious--has reached the tropical western Atlantic, where its reproductive rate is soaring. Invasive species expert, Lad Akins, of the Reef Environmental Education Foundation; along with College of the Bahamas marine science intern, Everton Joseph; and specimen collector for the Bermuda Aquarium, Chris Flook, team up in the waters of the Bahamas, where they dive, collect, tag and dissect, to better understand the invader in its new home. They'll run key field experiments, to identify potential controls, and assess the likely impacts of the invasion, on fragile reef ecosystems and ocean-based economies.

In our final installment from Burning the Future, we learn how individuals organizing on a grass-roots level can make a difference! Citizens, lawyers, physicians, and even pilots all come together in support of a common cause: stopping mountaintop removal in West Virginia coal mining.

This week's excerpt from Burning the Future: Coal in America examines the effects of coal on global warming. Coal-burned power plants are the largest CO2 emitters in the United States, and US emissions of carbon represent 25% of the world's contribution to global warming. Is clean coal the answer?

This week's Radio Ecoshock broadcast is about past greenhouse worlds, quick climate shifts, and mass extinctions caused by changes to the atmosphere. Dr. Andrew Glikson studies comet/asteroid impacts, volcanoes, and past climates. He's been doing it for 40 years. While studying the oldest record of life on Earth, in the Australian outback, Glikson found a relationship between comet or asteroid impacts and the generation of living things. We do not yet know whether life forms (such as bacteria) actually arrived from outer space - or whether the impact generated energy and unique chemical conditions that caused certain natural reactions to duplicate themselves. All that is a side issue to this speech, which is an education on the dominating role of the atmosphere in determining the state of life on Earth. Whether caused by impacts or volcanoes, or even gradual tilts in the Earth axis, a changing atmosphere can make life luxurious - or kill off up to 90% of all species. The science explained by Andrew Glikson in this speech find a parallel in the book "Under A Green Sky" by Peter Ward, a scientist in Washington State. We are talking, for example, about the Permian mass extinction, about 200 million years ago. The ocean lost it's oxygen, and life surived in only a few pockets of the ocean. Most land species were exterminated. Of the five past great extinctions (we are apparently living in the 6th extinction now) - FOUR WERE CAUSED BY CLIMATE CHANGE. Not hits from outer space. For the survival of our species, we need to know what happened - and few people alive know more than Andrew Glikson, as he summarizes not only his own research, but the general science now developing in the field. This speech from Australia National University explains our current shift toward a hot-state planet - much faster than ever before. It has been slightly modified for radio, (to fit in an hour) with the permission of Dr. Glikson. Learn about your planet (or die?)

Do you ever wonder where the juice to charge your iPod was produced? Like over half the electricity in the United States, probably from a coal-fired power plant run on coal from the mountains of West Virginia. This reliance on coal raises a score of questions about people, land, and a region's future. In the first of a three-part series of excerpts from "Burning the Future: Coal in America", we meet some of the West Virginians affected by our country's coal policy and see some of the health and ecological costs wrought by it.

Jonesing for spectacular nature photography? You got it! The Madison Valley, just north of Yellowstone, is a richly diverse ecosystem where just about every big-game species in Montana can be found. Grizzly and black bears, wolverines, elk, deer, moose, and pronghorns all use the Valley for seasonal migration, food, and breeding. However, development and the resulting fragmentation of large, interconnected ranges put this habitat at risk for the animals, especially wolverines, which are particularly intolerant of human activity and require vast ranges for their survival. K.C. Breen shows us how human encroachment in the Valley is being mitigated for wildlife's sake in "Yellowstone's Wildlife Highway: Promoting Connectivity in the Madison Valley".

There is music associated with tides and the rotation of the moon. We speak to a professor of geology at Western Washington University who is helping his students better understand the universe by listening. Then, we visit a cafe that caters to new moms and their kids.

And now for something wonderfully different! Papiroflexia (Spanish for Origami) is the animated tale of Fred, a skillful paper folder who could shape the world with his hands. Joaquin Baldwin used Photoshop and AfterEffects to create this fanciful animation that may resonate with many of us who would like to mold the human world into one just a little more natural.
