More benefits of green neighborhoods
September 4, 2014 02:32 PM - Oregon State Universtity
Mothers who live in neighborhoods with plenty of grass, trees or other green vegetation are more likely to deliver at full term and their babies are born at higher weights, compared to mothers who live in urban areas that aren’t as green, a new study shows. The findings held up even when results were adjusted for factors such as neighborhood income, exposure to air pollution, noise, and neighborhood walkability, according to researchers at Oregon State University and the University of British Columbia.
The tragic fate of the Passenger Pigeon
September 3, 2014 01:46 PM - Joel Greenberg, Yale Environment360
This September 1 is the 100th anniversary of a landmark event in the history of biodiversity. On that day in 1914, at about one o'clock in the afternoon, Martha - the last surviving passenger pigeon - died at the Cincinnati Zoo. It is extraordinary to know with virtual certainty the day and hour when a species ceases to be a living entity. And it was a stunning development because less than half a century earlier, the passenger pigeon had been the most abundant bird in North America, if not the world. As late as the 1860s, passenger pigeons had likely numbered in the billions, and their population was neither evenly distributed across the landscape nor in any way subtle. These birds had a propensity for forming huge aggregations that are difficult to imagine today. John James Audubon, America's best-known student of birds, recorded a flight of passenger pigeons along the Ohio River in Kentucky that eclipsed the sun for three days. Other accounts, written over the course of three centuries and in several languages, testify to the birds darkening the sky for hours at a time over the major cities of the eastern third of the United States and Canada.
California FINALLY gets serious about protecting its groundwater
September 3, 2014 07:43 AM - Union of Concerned Scientists
As California suffers through the third year of a record-breaking drought, state lawmakers agreed today to require more sweeping oversight of the state’s groundwater resources. California legislators approved Senate Bill 1168 and Assembly Bill 1739, which together call for stricter management of groundwater supplies by local agencies while giving the state the ability to step in when necessary. Up until now, California was the only state in the nation that did not comprehensively monitor or regulate groundwater.
Bike sharing benefits
September 2, 2014 07:27 AM - Raz Godelnik , Triple Pundit
While the sharing economy seems to have a growing number of fans, it also seems to generate more questions about its economic and social impacts. Interestingly, one part that is still missing from these discussions (well, not entirely) is the environmental impacts of the sharing economy. The general notion is that the sharing economy has a positive environmental impact as it promotes a greater use of underutilized assets. But is this true?
Puffins in New England
August 29, 2014 03:36 PM - PETER BAKER/ecoRI News contributor
I can't help but smile when I see a puffin, and I know I'm not alone. Thousands of people board tour boats each summer in Maine to get a glimpse of these charming seabirds with their tuxedo plumage and rainbow beaks. But what's in those beaks is serious business. The forage fish that puffin parents bring back to their island nests mean the difference between life and death for the chicks, and the past few years offer stark evidence of what happens when those fish become scarce.
Reducing Water Scarcity
August 29, 2014 02:53 PM - McGill University
Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries in 2016. Irrigation techniques, industrial and residential habits combined with climate change lie at the root of the problem. But despite what appears to be an insurmountable problem, according to researchers from McGill and Utrecht University it is possible to turn the situation around and significantly reduce water scarcity in just over 35 years.
Abandoned landfills are a big problem
August 29, 2014 10:30 AM - Alex Peel, Planet Earth Online
Abandoned landfill sites throughout the UK routinely leach polluting chemicals into rivers, say scientists. At Port Meadow alone, on the outskirts of Oxford, they estimate 27.5 tonnes of ammonium a year find their way from landfill into the River Thames. The researchers say it could be happening at thousands of sites around the UK.
Study Suggests More Research before Fracking Continues
August 29, 2014 07:22 AM - ClickGreen Staff, ClickGreen
An independent report on fracking has recommended a temporary moratorium on the controversial process and says that communities should give permission before it can proceed. The interdisciplinary expert panel set up by the Nova Scotia regional government says the science of fracking is relatively unknown and therefore its introduction should be delayed in the Province until the science and its environmental effects are better understood.
"Global Roadmap" Created to Balance Development with Environmental Protection
August 28, 2014 11:49 AM - Morgan Erickson-Davis, MONGABAY.COM
Roads make it possible to bring goods to market, to get to the office, to log a forest, to hunt its wildlife. Without roads, human society as we know it could not exist. However, to build roads, trees must be cleared and swamps drained, shrinking valuable wildlife habitat and fragmenting populations in the process. A new study, published today in Nature, unveils an innovative map that defines which areas of the world would best be used to build roads — and which should be left alone. Scientists estimate more than 25 million kilometers of new roads will be built worldwide by 2050, representing a 60 percent increase over 2010 numbers. Many of these are slated for environmentally valuable places with high numbers of unique species and pristine forest, such as the Amazon Basin.
Monarch Butterflies need Endangered Species Act protection
August 28, 2014 09:49 AM - Alicia Graef, Care2
As monarch butterflies are beginning their epic migration from Canada and the U.S. to Mexico for the winter, concerns about the drastic rate at which they're disappearing from the landscape have led environmental and health organizations to petition the government for federal protection. This week, the Center for Biological Diversity, Center for Food Safety, Xerces Society and monarch scientist Dr. Lincoln Brower filed a legal petition with the U.S. Fish and Wildlife Service seeking protection for monarchs under the Endangered Species Act.
