Patterns of Paper Pollution

Photographer J. Henry Fair has covered important environmental stories for Discover, from pork farms to toxic fertilizer byproducts. In January, powerHouse Books will be releasing Fair’s book The Day After Tomorrow: Images of Our Earth in Crisis, which includes essays from James Hansen, Allen Hershkowitz, and Frances May. Fair writes:

“Tremendous research has gone into understanding what is seen in these images. Information was gathered from numerous sources: newspapers, websites, the EPA (Environmental Protection Agency), EIA (Energy Information Agency), environmental groups, satellite images, and other sources within and outside of government. However, even these attempts at exposing the problem at hand can sometimes fall short. Due to exemptions granted to powerful industries, some of the most egregious industrial scars are “off the record.” The notorious Bevill Amendment to the RCRA (Resource Conservation and Recovery Act) is particularly damaging. For instance, the uranium content of phosphate fertilizer waste is well known, but due to RCRA exemptions, appears nowhere “on the record,” and thus the industry escapes the expense of proper handling. Also, one can only photograph what can be seen; often the most dangerous pollutants are invisible.”

Above is an image from the book showing a waste from a paper products factory in Baton Rouge, Louisiana—aerators have created a pattern in foam on the surface of the pool. This image was one that Fair made during his initial investigation of industrial regions around the Mississippi from the air. Fair often researches a topic extensively, and identifies locations using Google Earth before traveling and hiring a local pilot.

Is That a Rain Forest in Your Gas Tank?

While palm oil biofuel production is a major source of income for Malaysia, clear-cutting the rain forest for the palm plantations also has dramatic ecological and social costs. Palm oil biofuel production growth is fuelling the rapid clearing of the most biodiverse tropical forest in the world, endangering species that need this habitat. In addition, forests contain large quantities of carbon which are released when they are burnt to make space for farming. Photographer Daniel Kukla started photographing the palm plantations in Borneo in October 2010:

“For me, the word ‘Borneo’ conjured up vivid dreams of lush impenetrable rain forests teeming with life. Upon my arrival to the island of Borneo I was confronted by the reality of this place where huge tracts of old growth rain forest have been cleared for oil palm plantations. After many long drives through the countryside seeing only palm plantations, I wanted to see the landscape might look like from a different vantage point. I took a small propeller plane around the southern part of Sabah to get this aerial shot. Despite the strange beauty to the verdant parallel lines and snaking dirt roads, I felt a sinking feeling while I was photographing. So much has already been lost and the plantations continue to eat away into the landscape.”

Science Returns to Biosphere 2

<div>In 1991, a crew of four women and four men in jumpsuits sealed themselves into the Biosphere's 3.14 acres containing diminutive versions of a rain forest, a desert, an ocean, a mangrove swamp, a savanna, and a farm. The Biosphere 2 project would attempt to copy earth's life systems as a prototype for a future colony on Mars. Despite some successes, the dramatic failures of the Biosphere 2 are what most people remember--crew members suffered from high levels of carbon dioxide in the sealed atmosphere, hunger, and interpersonal conflicts. Today, the <a href="http://www.b2science.org/">Biosphere</a> is being used by scientists as unique lab space that is ideal for studying climate change impacts. <br /><br />Photographer <a href="http://www.douglasadesko.com/">Douglas Adesko</a> spent a few in Arizona days at the Biosphere, making a series of images to accompany the article "Life Under the Bubble" by Jordan Fisher Smith in Discover's October issue: "The natural environments are pretty cool, the most beautiful one is the desert. But the architecture is truly impressive. Huge empty enclosed spaces are always compelling, and the farm area is about the biggest I've been in--and it's all windows with a great view. The place has that quality of beautiful decay that's always seductive, but with a twist, since it's really not that old. Other parts just look cruddy. To me the most interesting place was the living spaces, which have a pronounced 80's trekkie look. These rooms really evoked the whole human drama of the place. You can feel the earnestness with which the participants approached the whole project, and this makes the story of their failure all the more interesting."</div>

Wild Africa’s Landscapers: Elephants and Rivers

During the dry season, when water is low, an elephant will dig holes to find water, drawing up to two gallons at a time with its trunk. Though these open wells are created by elephants, other wildlife also depend on them for survival. After elephants leave an area, smaller animals rush to the watering holes dug by the elephants. Elephants are essential for creating worn paths through the thick forests, excavating trees in the open savannahs, and unearthing water wherever it is needed.
<p>Photographer Alex Bernasconi hopes these images invite us to reflect on our relationship to the natural world. Bernasconi is motivated by a sense of urgency to counteract the destruction of nature: "It is the stark contrast between the environment in which we are accustomed to live and the one we are putting in jeopardy that has impelled me to photograph and record the natural world. It is the wilder places that preserve intact the primeval emotions that lie dormant in all of us. These are the essence of life."</p>

Ice Worms–the Least Charismatic Victims of Climate Change?

The brown squiggles you see here are ice worms making their living on the surface of the Whitechuck Glacier in the Cascade Mountains of Washington State. These relatives of earthworms—seen here alongside a disintegrating balloon littering the ice—are found only on the glaciers of the North American west coast, where they graze on algae and bacteria. Unlike other animals, the worms have a metabolism that seems to increase at lower temperatures; they typically die above 50 degrees Fahrenheit, and their tissues begin to break down at about 70 degrees. Some glaciers house more than 250 worms per square foot of ice, but as glaciers in the region recede, the worms are expected to disappear along with them.

They can be hard to photograph, because they avoid light and mostly appear at night. Photographer Ethan Welty: “I’d found balloons snagged on high peaks in the Cascades before, but there was something particularly alarming about the one I found on Whitechuck Glacier, the juxtaposition of the tangly green appendages of the balloon with the delicate black filaments of the surrounding ice worms.”
