Children benefit from getting outdoors
February 7, 2015 08:42 AM - Click Green staff
The health benefits of active outdoor pursuits over sedentary indoor pastimes are well known and increasingly highlighted in the battle against childhood obesity and its long-term consequences.
People of all ages extol the virtues of getting some fresh air, particularly for a generation of children in which, according to a Mothercare survey last year, more than a quarter play outside for less than half an hour a week.
Study Finds Leaks in Boston's Natural Gas Pipelines
February 2, 2015 04:37 PM - S.E. Smith, Care2
A team of researchers led by Kathryn McKain of Harvard University has recently discovered that approximately three percent of the natural gas delivered to Boston leaks directly into the atmosphere, taking with it a heavy load of methane, a known greenhouse gas. Their study doesn’t just have significant environmental implications: It’s estimated that the city is losing around $90 million to leaks every year. Correcting leaks is a relatively straightforward task, though it would require some investment in natural gas infrastructure and consumer education. However, these costs would be mitigated by the substantial savings offered if Boston was able to cut down on its methane problem.
Millions may be exposed to arsenic in private well water
February 2, 2015 09:29 AM - The Earth Institute - Columbia University
Naturally occurring arsenic in private wells threatens people in many U.S. states and parts of Canada, according to a package of a dozen scientific papers to be published next week. The studies, focused mainly on New England but applicable elsewhere, say private wells present continuing risks due to almost nonexistent regulation in most states, homeowner inaction and inadequate mitigation measures. The reports also shed new light on the geologic mechanisms behind the contamination. The studies come amid new evidence that even low doses of arsenic may reduce IQ in children, in addition to well documented risks of heart disease, cancer and reduced lung function. The reports comprise a special section in the journal Science of the Total Environment.
New analysis explores trends in global plastic consumption and recycling
January 28, 2015 03:35 PM - Gaelle Gourmelon, Worldwatch Institute
For more than 50 years, global production of plastic has continued to rise. Some 299 million tons of plastics were produced in 2013, representing a 4 percent increase over 2012. Recovery and recycling, however, remain insufficient, and millions of tons of plastics end up in landfills and oceans each year, writes Gaelle Gourmelon, Communications and Marketing Manager at the Worldwatch Institute, in the Institute’s latest Vital Signs Online article.
Pollution Blamed as Leading Cause of Death in Developing World
January 28, 2015 08:51 AM - Alexis Petru, Triple Pundit
In 2012, pollution – in the form of contaminated soil, water, and both indoor and outdoor air – was responsible for 8.4 million deaths in developing countries, finds Pollution: The Silent Killer of Millions in Poor Countries. That’s almost three times more deaths than those caused by malaria, HIV/AIDS and tuberculosis combined: Malaria claimed 600,000 lives in 2012, HIV/AIDS caused 1.5 million deaths and tuberculosis killed 900,000 individuals.

How the environment shapes our immune system
January 15, 2015 04:32 PM - Emily Conover, Science/AAAS
Why did you get the flu this winter, but your co-workers didn’t? The answer, according to a new study of twins, may have less to do with your genes and more to do with your environment—including your past exposure to pathogens and vaccines. Our immune system is incredibly complex, with diverse armies of white blood cells and signal-sending proteins coursing through our veins, ready to mount an attack on would-be invaders. Everyone’s immune system is slightly different—a unique mixture of hundreds of these cells and proteins. But the main driver of this variation is unclear. Although scientists know that our immune system can adapt to our environment—that’s why vaccines work, for instance—it is also built by our genes.
Bolt EV concept car from GM could help mainstream electric cars
January 15, 2015 06:57 AM - Leon Kaye , Triple Pundit
Concept cars at automobile shows generally offer the following: great opps for selfies, dreams over driving a vehicle that will never exist and, of course, the occasional eye roll. But this week at the North American International Auto Show (NAIAS) in Detroit, one concept car dazzled because of its design and its potential to transform the automobile industry: General Motors’ (GM) Chevrolet Bolt EV, which could hit the market as soon as 2017.
The Bolt is a huge step closer toward the holy grail of electric vehicles (EVs): affordability and sustainability — the latter of which in this case is defined by range, the current bugaboo of most EVs. Sure, we love Tesla for its phenomenal design and range of 265 miles between charges. Unfortunately, the sticker price, which ranges between $70,000 and $90,000, is out of range of most of our budgets. GM’s Chevy Spark EV could be a car for the rest of us, with a price of about $20,000 after federal rebates. But with a range of about 82 miles, it fails to snag interest from most consumers due to that massive hurdle: “range anxiety.”
Salting Roads takes a Toll on the Environment
January 14, 2015 10:49 AM - Kevin Mathews, Care2
The United States has a salt problem, and it extends well beyond the excessive sodium we consume in our diets. In the winter months, municipalities rely on dumping salt on the roads to minimize the effects of ice. Altogether, the U.S. uses ten times the amount of salt on roadways than it does in the processed foods we consume. While the salt may help to keep drivers safe, it does come at a cost:
1. It Increases Our Own Salt Consumption
You can throw salt down on roads, but you can’t force it to stay there. In due time, salt makes its ways into nearby waterways where it lingers. As a result, a lot of the water we wind up drinking has higher levels of salt than it would otherwise. Vox cites a study that finds 84% of city-adjacent streams have higher levels of chloride thanks specifically to these road-salting techniques. Apparently, during the months following salted roads, 29% of these streams have more salt than the federal “safety limits” for drinking water allow.
Is meaningful action to address climate change possible given our economic systems?
January 12, 2015 06:19 AM - , Triple Pundit
It’s increasingly obvious that the global economic system, and particularly the current brand of U.S. capitalism, are not really compatible with the actions needed to combat climate change.
Naomi Klein makes this point clear in “This Changes Everything,” which is both a passionate and controversial polemic and a reasoned discussion of the issues and forces stalling, and indeed preventing, a comprehensive response to climate change.
The problem is not the political and ideological divisions or scientific “debate,” which are hard enough to deal with — it’s mainly about money, according to Klein. The book’s subtitle is compelling: Capitalism vs. The Climate. Simply put: “Our economic system and our planetary system are now at war.”
