Colorado & Oceans // Nitrogen & Snails

Feature #1 (time mark 5:30) When people think of Colorado, they usually don’t think about “oceans”. After all, Colorado doesn’t have much of a coastline these days, though it was definitely had oceanfront property a few hundred million years ago. However, being in a landlocked state doesn’t mean that there isn’t any thing we can do to impact the health and ecology of the ocean and marine biology. Co-host Joel Parker talks with Vicki Goldstein, founder and president of the Colorado Ocean Coalition about the “Making Waves in Colorado” symposium and what all of us around the world (leaving near or far from oceans) do that impact and can help oceans.

Feature #2 (time mark 14:10) Nitrogen – we can’t live without it, but you can have too much of a good thing. In its gaseous form nitrogen is harmless and makes up nearly 80 percent of the atmosphere. The worldwide population never would have reached 7 billion people without nitrogen, in the form of chemical fertilizer. But excess nitrogen –from fertilizer runoff, manure, human sewage and other sources is wreaking havoc on the environment. Co-host Susan Moran talks with John Mischler, a PhD student at CU Boulder, who is researching worms and snails in Colorado and Africa. He talks about how excess nutrients in ponds, lakes and elsewhere can lead to the spread of parasitic disease from trematodes to snails to us.

Pine Beetle Kill // Plight of Sharks

"Empire of the Beetle" by Andrew Nikiforuk — “Empire of the Beetle” by Andrew Nikiforuk

Feature #1: If you live on the Front Range, or just about anywhere else in Colorado, you don’t have to go far to notice huge swaths of rusty brown that have replaced green conifer forests. By now, many people are familiar at least with the devastating effects of the mountain pine beetle. But far fewer may understand just how these voracious insects actually make their living, or that this epidemic — and its causes and triggers — are far more nuanced, and controversial, than meets the eye. How On Earth co-host Susan Moran talks with Canadian journalist Andrew Nikiforuk about the beetles that have been gorging with impunity on lodgepole pine, spruce and other forests from British Columbia down nearly to Mexico. His new book is called The Empire of the Beetle: How Human Folly and a Tiny Bug Are Killing North America’s Great Forests.Previously, he wrote a best-selling book called Tar Sands.

demon-fish-travels-through-the-hidden-world-of-sharks — “Demon Fish” by Juliet Eilperin

Feature #2: Sharks have a special place in the human psyche. Perhaps it is a combination of the mystery of the depths of the ocean and natural fear and awe of powerful beasts that can kill humans with a single bite. But these predators also are key players in the ocean’s ecosystem. The science and legends of sharks are the subject of a new book called “Demon Fish: Travels Through the Hidden World of Sharks” by Juliet Eilperin, the environmental science and policy reporter for The Washington Post. How On Earth’s Joel Parker talks with Juliet about her book. Listen to the extended interview here.

Pluto’s Moons // Wildlife Preservation

(credit: NASA, ESA, M. Showalter, Z. Levay)”]Feature #1:
Last month, astronomers working on the Hubble Space Telescope announced the discovery of another, fourth moon around Pluto; this moon is so small that it could fit easily inside Boulder County (a pretty tricky thing to find at a distance of three and a half billion miles). The researchers who found the new moon were making observations in support of NASA’s New Horizons spacecraft, which is en route to fly by and study Pluto in 2015, and continue onward to explore the mysterious region beyond Pluto’s orbit known as the Kuiper Belt. How On Earth’s Ted Burnham recently met with Alan Stern, principal investigator on New Horizons, to talk about what the discovery means for that mission. [An extended version of the interview also is available.]

Feature #2:
The significant loss of species on Earth is primarily due to human destruction of habitats, forests and other wild nature, to make room for new development and agriculture. Climate change is also accelerating the rate of species extinction. Among the efforts worldwide to protect wilderness and nature so wild animals can survive is a Boulder-based nonprofit called The WILD Foundation. Harvey Locke is the organization’s vice president for conservation strategy and he helped launch the Yellowstone to Yukon Conservation Initiative (Y2Y) several years ago and oversees a global campaign called Nature Needs Half. Y2Y’s goal is to create a continuous 2,000-mile corridor for wildlife from Yellowstone National Park in the U.S. to the Yukon in Northern Canada. Harvey joins us in the studio to talk about that campaign and the science behind wildlife preservation targets.

Ocean Acidification // Citizen Science

feature_images_2011jul12 — Top Image: Ocean Acidification process. Bottom Image: New Horizons spacecraft flies by a Kuiper belt object.

Feature #1: Many problems plague the oceans and the fish and other species that inhabit them: overfishing, pollution, and much more. But perhaps the greatest threat to sea life – and possibly to humans – is ocean acidification. That’s when the chemistry of the ocean changes and causes seawater to become more acidic because the ocean is absorbing carbon dioxide from the atmosphere. This increase in ocean acidity makes it difficult for many plants and animals in the ocean to make or maintain their shells or skeletons. The head of the National Oceanic and Atmospheric Administration (NOAA), Jane Lubchenco, recently said that the ocean is becoming more acidic at rates not seen for at least 20 million years, and that’s due mostly to increases in CO2 in the atmosphere. The threat is so grave that NOAA recently created a distinct Ocean Acidification Program. In May, Dr. Libby Jewett was appointed the first director of the program. We talk with Dr. Jewett find out more about the problem and what she aims to do about it.

Feature #2: Some sciences have a tradition of fruitful interactions between professional researchers and amateurs, and this has been made even more accessible with data being able to be shared over the internet across the world. Dr. Pamela Gay, an Astronomer at Southern Illinois University, Edwardsville, is the architect and participant in many such collaborations. In addition to her teaching and research, she does extensive public outreach to share the excitement of astronomy (such as her podcast AstronomyCast.com) and even finds ways to let anyone with an internet connection make new scientific discoveries and find new worlds that will be visited by spacecraft (IceHunters.org). We talk with Dr. Gay about the Zooniverse and her hunt for of icy objects in the outer solar system.

Science Education, Evolution & Creationism

At its most basic level, science can be considered as non-political or at least politically neutral: science is dedicated to the collection of facts and interpreting them to help us understand the universe and how it works. For that reason, many people – one may even say our culture in general – places a high value in being scientifically literate. Or at least we pay lip service to that idea. But when the results of science end up contradicting and conflicting with other ideals such as religious beliefs, personal behaviors, or vested interests, then science can become very political. Perhaps the two most visible examples of this politicization of science are in the areas of climate change and evolution, where the discussion ranges from the White House and Congress to local school boards and textbooks. Our guest today has front line experience in several aspects of science and education. Dr. Paul Strode is a biology teacher in the Boulder Valley School District, and has been an instructor of ecology and evolutionary biology at the University of Colorado. Dr. Strode is co-author of the book: “Why Evolution Works (and Creationism Fails)” – also available and reviews here and here.

Cell Phone Safety

The World Health Organization has officially listed cells phones as a possible carcinogen. One expert who’s not surprised at the designation is University of Colorado, distinguished professor Frank Barnes. For decades, Barnes has cobbled together hard-to-find research dollars to study the biological effects of magnetic fields and radiation, including cell phone radiation. In 2008, he chaired a National Research Council report that called for more research into the health effects of all kinds of wireless technologies, including laptop computers, wireless phones, and cell phones. In today’s show, Frank Barnes talks with How on Earth’s Shelley Schlender about cell phone safety.

This week co-host Susan Moran speaks with Dr. Doug Kenney, director of the Western Water Policy Program at the Natural Resources Law Center at the University of Colorado, Boulder’s law school. Kenney sheds light on the Colorado River Compact and how population growth, climate change, and water politics, are expected to further threaten our future water supply.

And Ted Burnham interviews skeptic and science writer Michael Shermer. His new book, “The Believing Brain,” presents a counter-intuitive explanation for how we form and reinforce our beliefs. Shermer draws on evidence from neuroscience, psychology and sociology to show that we often form beliefs first, and only then look for reasons to believe.
