A federal judge has found oil company BP responsible for the April 2010 Deepwater Horizon oil rig explosion and resulting oil spill. Now the question is how much should BP pay for the damage caused by 3.19 million barrels of oil that poured into the Gulf of Mexico. Some argue that BP should receive the maximum penalty for the environmental and economic damage caused by the spill. But BP wants credit for the money its has already spent on damages and cleanup. Listen to learn more about this complicated decision.

What you eat doesn’t just impact you; it impacts the environment. This is the argument that some nutritionists are presenting to U.S. Congressional Dietary Guideline Advisory Committee. They suggest Congress should consider the agricultural practices and the environmental impact of some foods when issuing nutrition guidelines. But that suggestion has not been well received by Congress. Listen to learn more about this effort to marry nutrition and environmentalism and the congressional backlash it has provoked.

Lego pieces have been washing up along beaches for nearly two decades after a shipping container slipped its cargo. Now, these Legos that were accidentally dropped into the sea are traveling around the world and turning up in places like Holland and Australia. Listen to this story to learn how that's possible.
The "cash for clunkers" program was a limited federal government program in the U.S. that gave people credits to trade in their old, gas guzzling, polluting cars for newer ones. The goal was to get older cars off the road to improve pollution. Because the “cash for clunkers” program did not allow the re-sale of old car engines, junkyards were forced to turn the cars into scrap metal. Listen to learn what this scrap metal can be turned into.
There is debate whether fish like the bluefin tuna are going to go extinct. Some argue that the decline in bluefin results from excessive fishing. However, long time bluefin fishers like Eric Stewart, disagree with this stance as he sees an increasing population of bluefin. Listen to hear from both sides, and how one bluefin tuna can swim across the entire ocean.
Scientists are creating bacteria batteries by using wastewater to generate electricity. The microbes from sewage can be harnessed to develop microbial fuel cells. The process could provide ways to provide energy in remote places for very little money. Listen to learn how scientists are developing this energy and what they are learning from it.
In this story, we hear from the head of Ecovative, a company that uses mycelium fibers from fungi to create useful and environmentally-friendly products. There are advantages of using mycelium fibers in place of plastics and foams, as well as challenges faced by the inventors in trying to create useful products. Listen to this story to hear how the engineering design process is described, as well as how scientists used this method to get to where they are today.
Oceans around the world see declines in healthy reefs. The increase in ocean temperatures due to global warming is one of the factors that cause this deterioration. Part of the coral reefs are endangered, but some corals are still thriving despite the increase in ocean temperature. Listen to learn who relies on coral reefs and what would happen if they completely deteriorated.
Ice is an essential component of the ecosystem of the Bering Sea region. For example, sea ice cover can dramatically affect the levels of phytoplankton which has enormous effects on the entire food web. In this public radio story we hear about the health of the Bering Sea ecology by studying scientific observations.
A geologist has turned decades worth of data into music. He created a multitrack sequencer for data instead of music. The data and music show a tight correlation between the amount of carbon dioxide and the amount of ice on the earth. Listen to hear what climate change sounds like and how it is helping scientists understand how humans affect our climate.
What happens when human structures and nature come into conflict? Ocean Beach in San Francisco is naturally eroding, but the consequence of this shifting shoreline is that a sewage treatment plant is put in peril. Without intervention, raw sewage could be dumped into the ocean. A rock wall has temporarily stabilized the pipeline, but not without complications. Listen to learn about the other solutions that are being considered, including construction of an artificial dune.
Energy experts are thinking about ways to replace coal that’s burned in American power stations. One alternative is to burn plants because they can produce fewer greenhouse gas emissions. This results in biomass power. Listen to learn about a movement in the Midwest that uses millions of acres of grass for biomass power.
Rare earth minerals are very important to today's electronics. Your iPod, laptop, and television use them. They make electronics light so they don't need much power. But the Chinese have a lock on the production of rare earth elements and this could become a problem for the US.
Human behavior continues to have an effect on marine life under the water. This story highlights how humans make the ocean so noisy. Scientists are worried that the noise is causing a disruption to animals and threatening their existence. Listen to learn what humans are doing and what can be changed.
The increasing acidity of the oceans could eventually affect your dinner plate. There is a decrease in the number of juvenile oysters known as "seed" due to the increase of CO2 in the ocean. Listen to learn how workers are dealing with the issues and how it affects the seafood we eat.
