Lawns are undeniably an American symbol. But what do they really symbolize? Pride and prosperity? Or waste and conformity? Gimme Green is a humorous look at the American obsession with the residential lawn and the effects it has on our environment, our wallets and our outlook on life. From the limitless subdivisions of Florida to sod farms in the arid southwest, Gimme Green peers behind the curtain of the $40-billion industry that fuels our nation's largest irrigated crop: the lawn.

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.

The modern age of landscape is an age of social interactions, markets, and developments are routinely channeled by preexistent hulks in the landscape as permanent and shaped as they come. State infrastructure and capital have made immense and irreversible the effects of building, in the form of corridors, monuments and waste, channeling everyday paths and interactions in new space. In the era of modern building, the secrets of landscape are constantly hidden in plain sight. Landscape writing offered a startlingly new category for political analysis when it emerged in the nineteenth century. Unlike studies of rhetoric, which stretch back through the classical tradition, structural studies of the phenomenology, politics, and psychology of landscape only matured in the nineteenth century, in the era when state intervention began to physically reshape the shape of trade, agriculture, and the city at an unprecedented scale. Psychologists like Georg Simmel and cultural critics like Walter Benjamin imported the science of rhetoric and the close attention to perception, analyzing the everyday spaces around them, and so developed a new science of landscape. This tradition ultimately informed diverse disciplines that took up landscape in the 1940s through 70s, including historical geography, military intelligence, American Studies, environmental psychology, and urban planning. I am currently experimenting in the culture of academic publication by using digital technologies like screencasting and wikis to help informally share work pursued by landscape scholars in different fields. The Landscape Studies Podcast shares talks given at academic conferences, while the Landsploitation Podcast shares experimental work in photography and film.

Check out this cut scene from Anne Aghion s film Ice People! In it, Dr. Adam Lewis from North Dakota State University talks about the remnants of the 14 million year old ancient lake at Mount Boreas in the Dry Valleys of Antarctica, where he and Pr. Allan Ashworth have been doing research. Tiny fossils tell big story!

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?)
