Green World: Introductory discussion

The material within these videos and articles will be discussed on our first day of class.

 They came. They drilled. They left, and in their aftermath are unplugged holes in the ground — orphaned coal-bed methane wells. To date, there are 6,924 plugged and abandoned coal-bed methane wells in Campbell County, according to the Wyoming Oil and Gas Conservation Commission. Of those wells, 5,202 are on fee or state land. The rest are on federal land. There also are wells that are orphaned — wells that the operators walked away from, leaving them unreclaimed. The responsibility of plugging these wells falls on the Oil and Gas Commission if the wells are on state or private land, or to the Bureau of Land Management, if they are on federal land. Since production peaked in 2009 at 580 million thousand cubic feet, the number of orphaned holes has been rising. There are about 1,220 abandoned wells on state and fee (private) land in Wyoming, most of which are in the Powder River Basin, according to Gov. Matt Mead’s office.

The mounds of kelp that recently washed onto local beaches point to a thriving offshore ecosystem created by restoration efforts over the past decade, experts say. Ten years ago, there was practically no kelp off Orange County’s coast. Pollution and an overabundance of predators such as sea urchins had decimated the kelp forests, killing 80 percent of what Southern California had a century ago. But over the past decade, environmentalists and others planted nearly 5 acres of kelp along coastal Southern California. They planted lab-grown kelp, transplanted healthy kelp from existing beds, released kelp spores and removed kelp predators, namely sea urchins, which can take over and obliterate a kelp forest if left unchecked. Those efforts seem to have paid off: The kelp is back. “This is just a sign of how healthy our kelp forest has become. Just 10 years ago, there was almost no kelp on the Orange County coast,” said Ray Hiemstra.

 This article was also fLaurie Barr is a hunter. Each year, around November, when the trees in Pennsylvania lose their foliage and the shrubs are nothing but bare sticks, offering no hiding place or cover, the hunting season begins. But Laurie Barr doesn’t carry a rifle or a crossbow; she doesn’t wear camouflage, and no faithful hounds lead the way. She doesn’t have to tread silently across the forest floor or keep her voice down because her quarry, if she is lucky enough to find it, is already dead – has been dead for decades. Armed with just a digital camera and a GPS device, Laurie Barr is hunting for what almost no one in Pennsylvania has heard of: orphaned oil and gas wells.

"In my opinion . . . just to get this many people talking about it (is a win)," Sheehan said. "It really is a David and Goliath story, and it's a story that will not go away no matter" which way the vote swings. Indeed, the initiative to impose a moratorium on the cultivation of genetically engineered crops in Maui County has become one of the most divisive issues the county has ever seen. It's driven thousands of residents to become more politically engaged this election season by marching in rallies, offering testimony before the Maui County Council or sitting down to analyze the piece of proposed legislation. But the initiative also has brought out combative behavior and vandalism that seldom characterize Hawaii elections. Extreme advocates have been caught on video removing campaign signs from private property and stopping in the middle of a roadway to yell at sign-wavers. In Lahaina, trees and buildings were spray-painted. For a county that has drawn the lowest voter turnout in the state in the past few elections, this singular initiative has driven more residents to get involved than ever before. It's uncertain what effects the surge of one-issue voters might have on other ballot measures or candidates. The "vote yes" side hopes to stop cultivation of genetically engineered crops until studies show they are safe for the environment and public health. The "vote no" side maintains such a ban would cost residents hundreds of jobs and taxpayers millions of dollars. And, it is not clearly written, they say.

Conventional wisdom says western Lake Erie’s toxic algae is supported by commercial farm runoff, animal manure, sewage spills, faulty septic tanks, and other major sources of nutrients responsible for putting much of the excessive phosphorus and nitrogen in the water. But that’s not the whole story. As Great Lakes scientists probe deeper into the weeds on this issue, they find such contributing factors as invasive species and climate change also foster algal growth. Invasive species and climate change don’t cause algal blooms, but they worsen them. That message often gets lost or misunderstood by a confused public that gets bombarded with information and wants to assign blame to a single issue, even though science doesn’t work that way.

Cape Town - Gauteng’s water was recently switched off because it was “so close to the edge” – and that’s just the beginning. The rest of the country is running on empty unless government spends 100 times more to secure our water supply. In more than half of the country, South Africans are using more water than what’s available. We are already using 98% of our available water supply, and 40% of our waste water treatment is in a “critical state”. A staggering 37% of our clean, drinkable water is being lost through inefficient ways of using water such as leaking pipes, dripping taps – and that is what’s being reported, the figure could be much higher.

While big companies make millions from El Salvador’s water-rich Nejapa municipality, locals have little or no access to water. Ana Luisa Najarro’s neighbours include some of the world’s largest corporations. Down the street from her house, giant drinks manufacturers have set up a series of factories and warehouses, bottling water and fizzy drinks for distribution across the country and export across central America. Coca-Cola is here, bottled by a subsidiary of SABMiller, the world’s second-largest brewer. A Mexican juice multinational has also moved in, as has a large bottled water company. Millions of dollars are made by major beverage businesses in Nejapa, an expanding industrial area in El Salvador near where Najarro lives. But despite living down the road, and on top of one of the country’s largest aquifers, she says she struggles every day to find enough clean water to drink. “Nejapa is a gold mine for water. It’s rich in water, and the communities have no access,” says Najarro, sitting in her garden. Her family has lived on this plot for three generations and she remembers a time when water was plentiful. “There were beautiful rivers you could go to and wash or swim. Now we can’t use the water for anything,” she says. “The water in the river is dirty; it’s dead water.” Just 20km north of the capital, San Salvador, Nejapa is an ecologically critical zone in central America’s smallest and most densely populated country. Salvadoran civil society groups say it is also a prime example of how unfettered competition over limited resources has created scenes of extreme water poverty next door to water-intensive industries

The more traffic pollution a pregnant woman is exposed to—especially during her third trimester—the greater chance her child will develop autism. That’s the conclusion of yet another study, this one published online in the October 2014 edition of the journal Epidemiology. It was only about a decade ago that scientists first began looking at whether air pollution impacted infant development. Today, four studies link traffic pollution exposure to autism, a developmental disorder characterized by social problems, communication difficulties, and repetitive behavior. According to lead author of the latest study, environmental epidemiologist Dr. Amy Kalkbrenner, the literature has been very consistent. “When looking at health impact in a human population, not a controlled animal experiment, getting this level of consistency is, in my assessment, notable,” she said.
