Thanks to favorable geography, innovative government policies, and businesses that see the benefits of clean energy investments, California is closing in on its goal of generating a third of its electricity from renewables by 2020.
In the second in an e360 video series, filmmaker Karim Chrobog travels to Seoul, South Korea, which has implemented a high-tech initiative that has dramatically reduced its food waste. Seoul’s efforts could serve as a model for how a major city can recycle discarded food and keep it out of landfills.
Scientists have theorized that tropical birds in mountainous regions will move uphill as the climate warms. But new research in the Peruvian Andes suggests that the birds will stay put and face a new threat — predator snakes that will climb into their territory to escape the heat.
A potential answer to California’s severe water shortages is groundwater banking, which involves creating incentives for municipalities, farmers, and other water users to percolate water down into sub-surface aquifers for later use.
Work has already begun on a $50 billion inter-ocean canal in Nicaragua that would cut through nature reserves and bring massive dredging and major ship traffic to Central America’s largest lake. Scientists and conservationists are warning that the project is an environmental disaster in the making.
On eBay and elsewhere on the Internet, illegal wildlife and wildlife parts — from elephant ivory to tiger skins to monkey and crocodile skulls — are being sold. Bringing an end to this illicit activity is proving to be a daunting challenge.
Offshore wind farms have been proliferating in the North Sea, with more huge projects planned. But conservationists are concerned this clean energy source could threaten seabird colonies that now thrive in the sea’s shallow waters.
In Germany, the Netherlands, Denmark and other countries, European governments are beginning to push farmers, industry, and municipalities to cut back on fertilizers and other sources of nitrogen that are causing serious environmental harm.
The main reason soaring greenhouse gas emissions have not caused air temperatures to rise more rapidly is that oceans have soaked up much of the heat. But new evidence suggests the oceans’ heat-buffering ability may be weakening.
For two towns in northern India, melting glaciers have had very different impacts — one town has benefited from flowing streams and bountiful harvests; but the other has seen its water supplies dry up and now is being forced to relocate.
Designed for the Future:
Practical Ideas for Sustainability
From packing materials made of mushrooms to buildings engineered to cool and power themselves, sustainable design can play a key role in helping people adapt to a changing planet. That’s a central message of the new book Designed for the Future
, in which more than 80 experts in sustainable design — architects, journalists, urban planners, and others — are asked to point to a specific project that gives them hope that a sustainable future is possible. Their selections vary widely, from communities that leave no carbon footprint to cutting-edge technological research programs. An e360
gallery highlights a few of the projects they say have inspired them.

The planet's protective ozone layer is in far better shape today thanks to the United Nations' Montreal Protocol, which came
Ozone hole without the Montreal Protocol
into force in 1987 and restricted the use of ozone-depleting substances such as CFCs, according to a new study in Nature Communications
. The researchers used 3D atmospheric chemistry modeling to look at what might have happened to the ozone layer had the treaty not been implemented. The findings suggest that the Antarctic ozone hole would have grown by an additional 40 percent by 2013 and, had ozone-depleting substances continued to increase, the ozone layer would have become significantly thinner over other parts of the globe. A very large ozone hole over the Arctic would have occurred during the exceptionally cold Arctic winter of 2010-2011 — colder temperatures cause more loss — and smaller Arctic ozone holes would have become a regular occurrence.
Interview: A Grassroots Effort to
Save Africa’s Most Endangered Ape
The Cross River gorilla population, with fewer than 300 individuals, has been pushed to the brink of extinction in equatorial
Africa. At the center of the fight to save this beleaguered ape population is Nigerian scientist Inaoyom Imong, who comes from the region and knows its forests — and its people — intimately. In a Yale e360
interview, Imong describes the various pressures that have reduced populations of this gorilla subspecies and explains how a few thousand people living in rural Nigeria and Cameroon hold the key to saving this magnificent ape.

The Environmental Protection Agency’s plan to regulate power plant emissions will cut carbon pollution to its lowest
Big Bend coal power plant in Florida
level since the 1980s, reducing CO2 emissions from power plants by 1.6 billion tons per year, according to an analysis
by the U.S. Energy Information Administration (EIA). The Clean Power Plan, which was proposed last June, sets goals for reducing carbon emissions from existing power plants by 2030. Under the plan, power sector CO2 emissions are projected to fall 25 percent below 2005 levels by 2020, and 34 percent below 2005 levels by 2030, the EIA analysis found. That would bring CO2 emissions from the power sector down to levels not seen since the early 1980s, the report notes.
A Remarkable Recovery for
The Oysters of Chesapeake Bay
In the past century, more than 90 percent of the world’s oyster beds have been lost to pollution, overharvesting, disease, and

coastal development. The renowned oysters of the Chesapeake Bay experienced a similar decline, with production nearly disappearing a decade ago. Now, however, Chesapeake Bay oysters are undergoing a remarkable recovery thanks to a brilliant oyster geneticist, improved state and federal management, the expansion of private hatchery operations, the cleanup of the bay, and some help in the form of average rain years and excellent reproductive oyster classes.
Malaysian authorities have uncovered timber “mass graves”
where illegal loggers attempted to conceal valuable timber

following a government crackdown on unlawful logging that started in February. The sites, located in the Belum-Temengor forest reserve, were revealed after the recent excavation of patches of land roughly the size of football fields, beneath which an estimated two stories of felled trees were stacked. “We believe that about 400 tons of logs worth more than RM1 million ($250,000 USD) were buried at the three locations and the culprits are waiting for the right time to dig them out and sell them,” says Anuar Mohd Noh, assistant commissioner for the Malaysian Anti-Corruption Commission (MACC), which conducted a joint operation with the country’s forestry department to track down illicit logging activities.
