With ever-greater quantities of seafood coming from aquaculture operations, some companies are working on ways to reduce the environmental impact of fish farming. In an interview with Yale Environment 360, Josh Goldman of Australis Aquaculture talks about his highly praised closed-containment fish farm in Massachusetts.

Biologists and conservationists maintain that establishing marine reserves — areas where fishing is off-limits or severely restricted — offers the best hope for recovery for our overstressed oceans. So why is such a small area of the world's oceans protected?

In recent years, palm oil development in Malaysia and Indonesia has devastated tropical forests there. With Brazil on the verge of its own palm oil boom, can sustainable cultivation of the crop actually help save the rainforest, rather than hastening its destruction?

Workers groups in South Korea report an unusually high incidence of cancers and other serious diseases among employees at Samsung’s semiconductor and other electronics plants. While the company denies any link, the pattern of illnesses is disturbingly similar to that seen at semiconductor facilities in the U.S. and Europe.

Paula Kahumbu runs a conservation organization with a distinctly 21st-century mission: Posting field blogs from conservationists to attract global support for wildlife protection. In an interview with Yale Environment 360, Kahumbu talks about her group’s triumphs and struggles as it battles to preserve Africa’s magnificent animals.

For millennia, the blanket of ice covering the Arctic Ocean protected the shore from damaging storms. But as that ice buffer disappears, increasingly powerful storm surges are eroding the coastline and sending walls of seawater inland, devastating Arctic ecosystems that support abundant wildlife.

In the past year, the world has seen a large number of extreme weather events, from the Russian heat wave last summer, to the severe flooding in Pakistan, to the recent tornadoes in the U.S. In a Yale Environment 360 forum, a panel of experts weighs in on whether the wild weather may be tied to increasing global temperatures.

The idea of economic growth as an unquestioned force for good is ingrained in the American psyche. But a longtime environmental leader argues it’s time for the U.S. to reinvent its economy into one that focuses on sustaining communities, family life, and the natural world.

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.

A decade after a brutal civil war, the West African nation of Liberia has partnered with the European Union on a novel system for protecting its remaining forests — marking every harvestable tree so it can be traced to its final destination. But given Liberia’s history of conflict and corruption, will it work?

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 disaster at the Fukushima plant in Japan convinced German Chancellor Angela Merkel that nuclear power would never again be a viable option for her country. Now Merkel has embarked on the world’s most ambitious plan to power an industrial economy on renewable sources of energy.

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.

Much attention has been paid to how global warming is affecting the world’s polar regions and glaciers. But a leading authority on tropical forests warns that rising temperatures could have an equally profound impact on rainforests and are already taking a toll on some tropical species.

Now in its seventh year, the EU’s carbon emissions trading system is the only international program designed to use market mechanisms to control CO2 emissions. But critics contend it has done little to slow the release of CO2 and argue that it should be significantly reformed — or scrapped.

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.
