Dissolving shells on the West Coast
April 30, 2014 01:10 PM - Robin Blackstone, ENN
Evidence now indicates that acidity of West Coast continental shelf waters is dissolving the shells of tiny free-swimming marine snails, called pteropods, the major food source for pink salmon, mackerel and herring. Funded by NOAA, the study estimates the percentage of pteropods in this region with dissolving shells due to ocean acidification has doubled in the nearshore habitat since the pre-industrial era and is on track to triple by 2050 when coastal waters become 70 percent more corrosive than in the pre-industrial era due to human-caused ocean acidification.
Eating endangered species in China could yield jail time
April 30, 2014 08:02 AM - Jeremy Hance, MONGABAY.COM
It's well known that much of the world's massive illegal wildlife trade ends up in China, including poached tigers, pangolins, and bears. But now those who order pangolin fetuses, tiger blood, or bear bile at a restaurant or market may see significant jail time. According to a reinterpretation of Chinese law by the Standing Committee of the National People's Congress (NPC), consumers of some 420 rare or endangered species in China could be sentenced to over ten years depending on the offense.
The EPA is enhancing sustainability: one Great Lake at a time
April 29, 2014 10:58 AM - Robin Blackstone, ENN
Two Great Lakes Restoration Initiative grants were awarded on Friday totaling $1 million earmarked towards Chicago green infrastructure projects. The projects will improve water quality in Lake Michigan. The infrastructure projects will prevent stormwater from carrying contamination into Lake Michigan.
Gardens in space
April 29, 2014 10:15 AM - Robin Blackstone, ENN
Catching floating raindrops, soil and seeds are making gardening just that much harder in the International Space Station. But this is how the astronauts function in their weightless environment. Even the plants don’t know which way to grow. Without gravity the soil and water simply float away unless contained; plant roots grow every which way. Without gravity the plant doesn’t know what is up or down. There is no rising or setting sun, just a 24 hour a day grow light.
France moving away from Nuclear power
April 27, 2014 09:48 AM - ClickGreen Staff, ClickGreen
France may be the world's most nuclear energy dependent country, but times are changing as the country looks to increase the amount of wind—sourced electricity in its power mix. When French President François Hollande took the reins of power in 2012 he pledged to reduce the country's nuclear dependency from 75% to 50% by 2025.
Illegal Fishing still a big problem in the US
April 26, 2014 07:33 AM - Richard Conniff, Yale Environment360
When people talk about illegal trafficking in wildlife, the glistening merchandise laid out on crushed ice in the supermarket seafood counter — from salmon to king crab — probably isn’t the first thing that comes to mind. But 90 percent of U.S. seafood is imported, and according to a new study in the journal Marine Policy, as much as a third of that is caught illegally or without proper documentation. The technical term is IUU fishing, for illegal, unreported, and unregulated fishing. But such improbable allies as members of the U.S. Senate now refer to it as "pirate fishing." And it ensnares seafood companies, supermarkets, and consumers alike in a trade that is arguably as problematic as trafficking in elephant tusks, rhino horns, and tiger bones.
Who came first: the farmer or the hunter-gatherer?
April 25, 2014 08:54 AM - Robin Blackstone, ENN
This is the question being asked by researchers from Uppsala and Stockholm Universities. And now with a genomic analysis of eleven Stone Age human remains from Scandinavia the researchers have concluded that the Stone Age farmers assimilated local hunter-gatherers who were historically lower in numbers than the farmers. There has been much debate as to when the transition between hunting-gathering and farming began. Now with DNA science being used on human material, scientists have a whole new way to learn about this sliver of time.
Unleashing the inner green consumer
April 24, 2014 11:08 AM - Click Green Staff, ClickGreen
Academics have uncovered a key influence in the consumer's decision to go green, whether it's recycling, composting or buying environmentally friendly products. Research from Concordia University's John Molson School of business, proves that even just asking ourselves, or predicting, whether we will engage in sustainable shopping behavior can increase the likelihood of following through — especially when there's an audience.
Cry for global STEM funding
April 24, 2014 10:50 AM - Oliver Girard, Center for International Forestry Research (CIFOR) , SciDevNet
In today's global economy, a workforce trained in science, technology, engineering, and math (STEM) is recognized as a primary driver of growth. Around the world, STEM education initiatives vary in scope, size, type, target populations and funding sources. What’s missing is a unified global mechanism for STEM education. Creating a Global STEM Fund would help support and implement effective and innovative STEM programs in developing countries. The NGO Cosmos Education, the STEM Innovation Camp in South Africa, the African Institute for Mathematical Sciences and the Bunengi STEM Africa are but a few examples of organizations and programs that could benefit.
Are Large Dams Economical?
April 23, 2014 08:51 AM - Editor, The Ecologist
A study of 245 large dams carried out at Oxford University shows that big hydropower is uneconomic. Actual costs are typically double pre-construction estimates - and have not improved over 70 years. Researchers at Oxford University have found that planners and policymakers systematically underestimate the costs and time required to implement large dam projects.
