Scientists advocate protective deep-sea treaty
February 28, 2014 10:00 AM - Nick Kennedy, SciDevNet
A new international agreement is needed to police the exploitation of the deep ocean because of the rising threats of deep-sea mining and bottom trawling for fish, say scientists. Speakers at a symposium this month (16 February) urged the UN to negotiate a new treaty for the deep ocean to supplement the UN Convention on the Law of the Sea.
One state addresses potholes through a new pothole alert system
February 27, 2014 10:43 AM - ENN Staff
As much of the northern hemisphere looks forward to the second half of the winter season, municipalities and regional governments are faced with rudimentary task of repairing potholes. Rutgers University instructor Wansoo Im, no doubt frustrated with the infrastructure meltdown himself, launched an app and website to map the biggest ones in his own home state of New Jersey. Aptly called NJPothole, the website plots potholes on maps to alert motorists (and maybe even municipal departments of public works dispatchers) of impending undercarriage attack.
Greener chemical cleanups
February 26, 2014 12:14 PM - Marianne English Spoon, University of Wisconsin
Cleaning up oil spills and metal contaminants in a low-impact, sustainable and inexpensive manner remains a challenge for companies and governments globally. But a group of researchers at UW—Madison is examining alternative materials that can be modified to absorb oil and chemicals. If further developed, the technology may offer a cheaper and "greener" method to absorb oil and heavy metals from water and other surfaces.
Passing the baton in oil spill research on the Gulf Coast
February 26, 2014 09:30 AM - Woods Hole Oceanographic Institution Media Relations Office
As part of on-going research nearly four years after the Deepwater Horizon oil spill, scientists from the Woods Hole Oceanographic Institution (WHOI) will team up with a group of high school students in Florida to collect remnants of oil from Gulf Coast beaches this week. Marine chemist Chris Reddy studies how the many compounds that compose petroleum hydrocarbon, or oil, behave and change over time after an oil spill. He and his researchers have collected and analyzed about 1,000 oil samples from the Gulf Coast since the Deepwater Horizon oil spill.
Free mobile green apps

Incorporating sound environmental decisions in our daily lives has been made easier with the availability of several green apps for the mobile device. Below is a list of five useful environmental apps that are free and feature discussions and motivators for carbon footprint identification and reduction, climate change, global forest cover, product scoring based upon environmental impact, and environmental actions all aimed at making better choices for sustainable living.
COLLEGIATE CORNER: Fossil Fuels vs. Renewable Resources
February 24, 2014 01:07 PM - Flavio Avalos, Class of 2015, Wakefield High School, Arlington, VA
Fossil fuels have been the main source of the energy all over the world. They increase the amount of CO2 emissions, and the emission of CO2 is a great cause of global warming in the atmosphere, destroying the atmospheric layers. What can we do to lower the demand of fossil fuels and become more eco friendly with renewable energy resources? The percent of US transportation sector consumption is 95.4% fossil fuels (Article 3), and this shows the reliance of the US on fossil fuels. As the Institute for Energy states, "Fossil Fuels make modern life possible" and that the only reason that our modern society works and the privileges we get are all due to the fact of fossil fuels (Article 3). Need I remind you: fossil fuels are limited and could go out?
Fracking residual waters
February 18, 2014 09:40 AM - Robin Blackstone, ENN
As fracking amongst Marcellus Shale in the northeastern part of the United States increases so does the concern over its process. Fracking is done utilizing a hydraulic fracturing process, which pumps a high-pressure mixture of water, chemicals and sand deep into the sedimentary formations to extract naturally occurring gas. The resultant wastewater is then stored in large impoundment ponds and closed container tanks until it can be piped to wastewater treatment plants. Once cleaned it is discharged into local streams or trucked to Ohio to be pumped deep down into another injection well or into another fracking operation.
Testing for environmental contaminants in wastewater biosolids
February 14, 2014 10:08 AM - Ken Kingery, Duke University
Every year waste treatment facilities in the United States process more than eight million tons of semi-solid sewage called biosolids -- about half of which is recycled into fertilizer and spread on crop land. The practice helps solve storage issues and produces revenue to support the treatment plants, but what else is being spread in that sludge?

It's Valentine's Day, and in supermarkets, drug stores and specialty shops across the country, shelves are lined with chocolates of every shape, size and variety. As you browse through endless heart-shaped boxes, consider this: The chocolate industry is in jeopardy, and if things don't change, there could be a worldwide cocoa deficit by the year 2020.
More contaminant troubles for West Virginia
February 13, 2014 09:18 AM - Judy Molland, Care2
On February 11, just one month after a chemical spill tainted drinking water for 300,000 people in and around the state's capital of Charleston, West Virginia experienced another environmental disaster: 100,000 gallons of coal slurry pour into stream.
