Photo Essay: How Pollution Is
Devastating an Indonesian Lake
More than 1,500 tons of fish suddenly turned up dead in Indonesia’s largest lake earlier this year, a mass asphyxiation caused by high pollution levels. The event threatened the livelihoods of hundreds of fish farmers and the drinking water for thousands of people, and it shed light on the rapidly declining conditions in Lake Toba, the world’s largest volcanic lake.

A new online tool
mapping active oil and gas wells on U.S. public lands shows that at least 74,000 people in six states

live within a half-mile of drilling sites. That close proximity puts these people at increased risk of cancer, heart disease, and respiratory problems from natural gas leaking from the wells, said the Wilderness Society, which together with Earthworks helped create the tool. In Wyoming, for example, 15,869 oil and gas facilities
operate on public land, and some 4,000 people live within a half-mile of them — the range that airborne pollutants from wells, such as benzene, can easily travel. The mapping tool is being released at a time when scientists, environmental groups, and policymakers are ramping up calls to reduce and regulate natural gas leaks
from drilling and storage sites in an effort to fight climate change, increase energy efficiency, and protect public health.
The Moth Snowstorm: Finding
True Value in Nature’s Riches
It is the blizzard of moths that Michael McCarthy remembers most vividly. As a boy, his family would take summer nighttime drives to the English coast,
and the car headlights and windshield would soon be so splattered with moths they would have to stop to clean them off. “That phenomenon has gone,” says McCarthy. “It’s disappeared because there has been a horrendous crash in moth numbers in the U.K.” His recent book, The Moth Snowstorm: Nature and Joy
, offers a defense of the natural world rooted in the joy and spiritual nourishment it provides. In an interview with Yale Environment 360
, McCarthy, a British journalist, talks about the loss of wildlife; how the decline in species abundance, as opposed to extinctions, is overlooked; and why he thinks putting a monetary value on so-called ecosystem services is too limiting. “You can say mangrove swamps are worth so many billion dollars,” he says. “But what about birdsong? How much is birdsong worth?”

A direct call to action by the Pope has apparently failed to inspire people to be concerned about climate change, according to a new national survey
public policy researchers at the University of Pennsylvania. Last year, Pope Francis release a 200-page papal letter entitled “Laudato Si
,” or “Be Praised,” that urged 1.1 billion Catholics to address climate change and live more sustainably. The new survey, published in the journal Climatic Change
, found those who had heard of the encyclical — both Catholics and non-Catholics — were no more concerned about global warming than those who hadn’t. Those who knew about the encyclical were also more politically polarized
in their acceptance or denial of climate change. The scientists used data from 1,381 20-minute phone interviews one week before the encyclical’s release and two weeks after it was published.
Public Art or Renewable Energy?
New Designs Aim to Produce Both
When the topic of energy infrastructure comes up, works of art don’t usually come to mind. But hundreds of such hybrid creations — part renewable power generators,

part large-scale art installations — now exist, at least on paper, as the result of a sustainable design competition known as the Land Art Generator Initiative
. Multi-disciplinary teams across the world have taken up the challenge to come up with buildable designs that produce renewable energy and “add value to public space, inspire, and educate.” In a photo essay, Yale Environment 360
highlights eight submissions to this year’s biennial competition, including the three winners announced this week. All designed for the waters off the Santa Monica Pier in Southern California, the systems range from a ring-shaped farm floating offshore to sail-like structures that harvest drinking water from fog.

creation of modern day snakes, according to two studies published week. The findings were discovered by two independent teams of researchers, which reported their results separately in the journals Current Biology
. Some snakes, including pythons and boas, still have tiny leg bones inside their bodies, remnants of this evolutionary history; but most species lost their legs starting about100 million years ago. The scientists traced the mutation back to a docking site for proteins, known as an enhancer, situated in front of the Sonic hedgehog
gene, which controls limb development. They found that the enhancer is simply switched off, not broken. When the missing DNA was fixed and the modified enhancer was put in mice, they grew legs like normal
