This September 1 marks the 100th anniversary of the death of Martha, the last known passenger pigeon on earth. The extinction of this once-abundant North American bird still stands as a cautionary tale.
Conflicts over water have long haunted the Middle East. Yet in the current fighting in Iraq, the major dams on the Tigris and Euphrates rivers are seen not just as strategic targets but as powerful weapons of war.
Hydraulic fracturing is about to move into the Canadian Arctic, with companies exploring the region's rich shale oil deposits. But many indigenous people and conservationists have serious concerns about the impact of fracking in more fragile northern environments.
Tainted Harvest: An e360 Special Report
Three decades of rapid economic development in China has left a troubling legacy – widespread soil pollution that has contaminated food crops and jeopardized public health. In a three-part series, Yale Environment 360 looks at a grave problem that has been labeled a “state secret” and that Chinese officials are only beginning to acknowledge.
Vultures are being killed on an unprecedented scale across Africa, with the latest slaughter perpetrated by elephant poachers who poison the scavenging birds so they won’t give away the location of their activities.
Small hydropower projects have the potential to bring electricity to millions of people now living off the grid. But experts warn that planners must carefully consider the cumulative effects of constructing too many small dams in a single watershed.
Along the Delaware River estuary, efforts are underway to restore wetlands lost due to centuries of human activity. With sea levels rising, coastal communities there and and elsewhere in the U.S. and Europe are realizing the value of wetlands as important buffers against flooding and tidal surges.
An increasing number of sewage treatment plants in the U.S. and Europe are processing food waste in anaerobic biodigesters, keeping more garbage out of landfills, reducing methane emissions, and producing energy to defray their operating costs.
Interview: Drones Are Emerging
As Valuable Conservation Tool
Ecologist Lian Pin Koh
is co-founder of a project called ConservationDrones.org
, which is pioneering the use of
Lian Pin Koh
low-cost drones in conservation efforts and biological research across the globe. In an interview with Yale Environment 360
, Koh, a researcher at the University of Adelaide, explains how drones – also known as unmanned aerial vehicles (UAVs) – can help monitor protected areas, collect data in inaccessible regions, and even deter poachers. “In just the last couple of months,” he says, “there has been tremendous interest from universities and other research institutes that finally see the value in this technology.”

A newly launched online database
illustrates the impacts of nearly 6,000 dams on the world's 50 major
river basins, ranking their ecological health according to indicators of river fragmentation, water quality, and biodiversity. The "State of the World's Rivers" project was developed by the advocacy organization International Rivers
and created using Google Earth. Users can compare the health of individual river basins, see the locations of existing and planned dams, and explore 10 of the most significant river basins in more depth. The 6,000 dams represented in the database are a small percentage of the more than 50,000 large dams that impact the world's rivers, the organization notes.
Green Innovations Are Bringing
Energy-Saving Technology Home
Advances in technology and consumer demand for energy-saving devices have made green technology
increasingly accessible. Many innovations are geared toward homeowners looking to lower not only their energy bills, but also the carbon footprints of their homes and daily activities. From solar-harvesting shingles and windows to shoe insoles that can power a smartphone, this Yale Environment 360
gallery explores a few of these energy-saving technologies.

The amount of U.S. oil shipped by rail rose 9 percent during the first seven months of the year compared to 2013, reaching 16,000 carloads per week in July,
according to the U.S. Energy Information Administration
(EIA). U.S. crude oil production reached an estimated 8.5 million barrels per day in June for the first time in 18 years and is driving the increase in rail transport
, the EIA said. Only 3 percent of petroleum shipped by rail in 2009 was crude oil; now crude accounts for more than half. Over the past three years, much of the oil has come from the Bakken Shale, primarily in North Dakota. Between 60 and 70 percent of the more than 1 million barrels per day of oil produced in North Dakota has been transported by rail so far in 2014, according to the North Dakota Pipeline Authority. The demand for rail cars has created a backlog that's been particularly worrisome for farmers, who say their grain is rotting before shipping space is available
to take it to market.
Interview: Making the Rights of
Farm Animals a Basic Green Issue
Conservation organizations have long sought to protect pandas, polar bears, and pelicans, but the welfare of
farm animals has largely been left to activist animal-welfare groups like the Humane Society of the United States
. For the past 10 years, that organization has been headed by the politically savvy Wayne Pacelle, who has greatly increased its visibility and influence. Under his leadership, the society has lobbied successfully to curb what it calls the worst excesses of “factory farms.” In an interview with Yale Environment 360
, Pacelle talked about how treatment of farm animals is linked to greenhouse gas emissions, why his group is promoting “meatless Mondays,” and why consumers should be willing to pay more for products from animals that are sustainably raised.
The Obama administration is aiming to forge a legally binding, international agreement that would cut fossil
fuel emissions and direct funds to poor nations dealing with climate change, without ratification from Congress, The New York Times
reports. The agreement would combine legally binding updates to an existing 1992 climate change treaty — allowing Obama to sidestep the constitutional requirement that treaties be ratified by two-thirds of the Senate — with voluntary pledges for specific emissions targets and aid to help poorer countries adapt to climate change. Nations would then be legally required to report progress toward their emissions targets at international meetings that would "name and shame" countries making slow or no progress, the Times
reports. Lawmakers from both political parties say that no climate agreement requiring congressional approval could be reached in the near future. Republican leaders are expected to oppose the agreement being worked on by the administration and say it would be an abuse of executive authority.
