Last year’s oil spill in the Gulf of Mexico severely damaged Louisiana’s oyster beds, one of the world’s last thriving wild oyster fisheries. In a Yale Environment 360 video, journalist Jon Brand reports on an experimental oyster farm in Louisiana that offers hope for a smoother recovery for the Gulf’s oysters and its oystermen.

Marine conservationist Charles Saylan believes the U.S. educational system is failing to create responsible citizens who consider themselves stewards of the environment. To do that, he says in a Yale Environment 360 interview, educators need to go beyond rhetoric and make environmental values a central part of a public education.

What if the ever-increasing amounts of carbon dioxide that are heating up the atmosphere could be used to produce an abundant supply of liquid fuels? The U.S. government and private labs are pursuing that Holy Grail of renewable energy — but for now the cost of large-scale production is prohibitive.

Scientists studying the effects of prenatal exposure to pesticides on the cognitive abilities of children have come to a troubling conclusion: Whether pregnant mothers are exposed to organophosphate pesticides in California fields or New York apartments, the chemicals appear to impair their children’s mental abilities.

Shortly after gaining independence in 1990, Namibia turned ownership of its wildlife back to the people. By using a system of community-based management, this southern African nation has avoided the fate of most others on the continent and registered a sharp increase in its key wildlife populations.

The recyclable plastic bags you get at the green grocer are not biodegradable. But product life-cycle assessments, which are about to become more prominent in the marketplace, fail to consider whether those bags will break down in landfills or just end up as litter.

Nissan chairman Carlos Ghosn believes the technology currently exists to produce affordable, all-electric cars that will find a global market. In an interview with Yale Environment 360, he talks about Nissan’s new Leaf and why he is confident that, despite earlier setbacks, the time for all-electric vehicles is now.

Despite soaring rhetoric and some promising proposals, President Obama is repeating the same mistakes that have doomed U.S. energy policy to failure for 40 years. Until Obama and Congress finally put a true price on the fossil fuels America consumes, the U.S. will continue its addiction to foreign oil and domestic coal.

One of the thorniest questions facing climate scientists is whether human-induced climate change is leading to more heat waves, floods, and extreme weather events. Now, employing increasingly sophisticated methods of studying weather extremes, climatologists say they are closer to answering that key question.

On the anniversary of the Deepwater Horizon explosion, the worst fears about the long-term damage from the oil spill have not been realized. But the big challenge is more fundamental: repairing the harm from the dams, levees, and canals that are devastating the Mississippi Delta and the Louisiana coast.

Three years after unveiling his plan for U.S. energy independence, which won praise from environmentalists for its reliance on wind power, Texas oilman T. Boone Pickens is back with a proposal to convert the U.S. trucking fleet to natural gas. But as his new plan gains traction, questions arise over how green it really is.

With contaminated water from Japan’s crippled Fukushima nuclear complex continuing to pour into the Pacific, scientists are concerned about how that radioactivity might affect marine life. Although the ocean’s capacity to dilute radiation is huge, signs are that nuclear isotopes are already moving up the local food chain.

A forbidding, 870-mile network of fences and guard towers once ran the length of Germany, separating East and West. Now, one of the world’s most unique nature reserves is being created along the old “Death Strip,” turning a monument to repression into a symbol of renewal.

The Japanese earthquake and tsunami remind us that we exist in geologic time and in a world where catastrophic events beyond our predicting may occur. These events — and the growing specter of climate change — show how precariously we exist on the surface of a volatile planet.

When wildlife biologists ventured into a Vermont cave this month, they found disturbing evidence that white-nose syndrome was continuing to take its toll on once-abundant bat populations. But the question remains: What can be done to halt the spread of this still-mysterious ailment?

A leading U.S. expert on nuclear energy discusses some of the fundamental failures that led to the intensifying nuclear drama in Japan and looks at what might lie in store for nuclear power worldwide.

Electric cars are finally coming to market in the U.S., but what is the future potential for this much-touted technology? A good way to find out would be to launch demonstration projects in selected U.S. cities to determine if, given incentives and the proper infrastructure, the public will truly embrace plug-in vehicles.

In recent months, several conservative governors have rejected federal funds to begin constructing high-speed rail lines in their states. But a high-speed rail advocate argues that such ideologically driven actions are folly, as other U.S. states and countries around the world are moving swiftly to embrace a technology that is essential for competitive 21st-century economies.

One of the tenets of conservation management holds that alien species are ecologically harmful. But a new study is pointing to research that demonstrates that some non-native plants and animals can have beneficial impacts.

As agriculture and energy production have made strides toward becoming more sustainable, the world’s fisheries have lagged behind. But restoring our beleaguered oceans to health will require an emphasis on diversification and conservation — and a more sensible mix of fishing practices.

For decades, deadly outbreaks of cholera were attributed to the spread of disease through poor sanitation. But recent research demonstrates how closely cholera is tied to environmental and hydrological factors and to weather patterns — all of which may lead to more frequent cholera outbreaks as the world warms.
