From understanding the cumulative impacts of widely used chemicals to preparing for life in a warming world, a host of environmental health issues now face medical experts. In an interview with Yale Environment 360, Lynn Goldman, dean of the George Washington University School of Public Health and Health Services, talks about meeting the challenges.

In the wake of the Fukushima meltdowns, some nations are looking to move away from nuclear power. But not China, which is proceeding with plans to build 36 reactors over the next decade. Now some experts are questioning whether China can safely operate a host of nuclear plants.

The contentious practice of hydrofracking to extract underground natural gas has now made its way to South Africa’s Karoo, a semi-desert known for its stark beauty and indigenous plants. But opposition is growing amid concern that fracking will deplete and pollute the area’s scarce water supplies.

Some skeptics have suggested the real culprit behind rising temperatures is increased solar activity. But a wide variety of data and experiments still provide no solid evidence to refute the scientific consensus that greenhouse gas emissions are the major reason the planet is heating up.

When Barack Obama won the presidency in 2008, environmentalists were optimistic that their issues would finally become a priority at the White House. So how is Obama doing? Yale Environment 360 asked a group of environmentalists and energy experts for their verdicts on the president's performance.

For two decades, the once-scenic Lake Taihu in eastern China has been choked with devastating algae blooms that have threatened drinking water for millions. Now, in a move that could provide lessons for other huge lakes worldwide, China is taking steps to restore Taihu’s ecological balance.

With global population expected to surpass 7 billion people this year, the staggering impact on an overtaxed planet is becoming more and more evident. A two-pronged response is imperative: empower women to make their own decisions on childbearing and rein in our excessive consumption of resources.

Building bike paths alone will not get people out of their cars in the U.S. and onto bicycles. To create a thriving bike culture in America’s cities, people must begin to view bicycling as Europeans do — not just as a way of exercising, but as a serious form of urban mass transportation.

A rapidly expanding universe of citizens’ groups, researchers, and environmental organizations are making use of social media and smart phone applications to document changes in the natural world and to mobilize support for taking action.

Phosphate has been essential to feeding the world since the Green Revolution, but its excessive use as a fertilizer has led to widespread pollution and eutrophication. Now, many of the world’s remaining reserves are starting to be depleted.

Exploiting North America’s largest oil deposit has destroyed vast stretches of Canada's boreal forest, arousing the ire of those opposed to this massive development of fossil fuels. Now those opponents are battling the Keystone XL pipeline, which would pass through environmentally sensitive Western lands as it moves the oil to market.

Even before this spring’s ominous clampdown on China’s public-interest lawyers, writers, and activists, the country’s fledgling environmental community felt the authorities’ noose tightening.

For eons, the polar marine food chain has been closely linked to the seasonal formation and retreat of sea ice. Now, as that ice rapidly melts in the Arctic and along the Antarctic Peninsula, this intricate web of life is undergoing major shifts, benefiting some creatures and putting others at risk.

Few places in the U.S. are as well suited to developing renewable energy as the contaminated sites known as “brownfields.” But as communities from Philadelphia to California are discovering, government support is critical to enable solar and wind entrepreneurs to make use of these abandoned lands.

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.
