Bottled Water Consumption Grows in US Sales of bottled water in the U.S. rose 4.1 percent to 9.1 billion gallons in 2011, an all-time high, according to the Beverage Marketing Corporation‘s annual survey. Despite numerous campaigns and education efforts, U.S. per capita consumption of bottled water has risen by 60 percent in the last 10 years, from 18.2 to 29.2 gallons per person. In 1976, Americans consumed 1.6 gallons of bottled water per person. While domestic non-sparkling water made up the vast majority of sales, even sales of imported water, which had seen precipitous drops during the recession years of 2008-10, inched up in 2011. The increase comes in spite of years of efforts by activists to draw attention to the financial and environmental costs of the bottled beverage, countering industry efforts to tempt consumers to drink the bottled stuff. How can we convince more people to use less bottled water? Some jurisdictions are trying laws to ban the bottle, including: What’s wrong with bottled water? Wrong.

Progress in Disaster Science 1. Scope and Instructions for Authors Progress in Disaster Science focuses on integrating research and policy in disaster research, and publishes original research papers and invited viewpoint articles on disaster risk reduction; response; emergency management and recovery. A key part of the Journal's Publication output will see key experts invited to assess and comment on the current trends in disaster research, as well as highlight key papers. In addition, the Journal will welcome original research into new innovations and approaches, with the following emphasis: The key criterion is that all papers submitted should report substantial progress in the field. 2. We publish high-quality papers in several different sections: A: Original Research B: Invited Papers: To add to the Original Research submitted, the Journal will also publish "Invited Viewpoint" articles, written by experts. All Papers in the Journal will be published Gold Open Access. Final Thought C. Hide full Aims & Scope

Portail documentaire Victory Against Ecosystem-Destroying Flaming Gorge Pipeline In a victory for endangered fish and other river species, the Federal Energy Regulatory Commission has — for a second time — rejected a permit for a massive, controversial pipeline that would be a disaster for the Colorado and Green rivers. The Flaming Gorge pipeline would suck an astonishing 81 billion gallons of water from the Green per year, dealing a potentially fatal blow to one of the West’s last great rivers — as well as to razorback suckers and Colorado pikeminnows. After legal intervention in the pipeline’s permit process by the Center for Biological Diversity and allies, the commission said the project was poorly defined and that its proponent, Wyco Power and Water, Inc., was dismally unprepared to get all the authorizations needed to build it. That means this outrageous attempt to deplete two rivers should be dead in the water. Large, warm-water fish, razorback suckers are native to the Colorado River basin.

CREN - Conservatoire Rhône Alpes des Espaces Naturels EPJ Photovoltaïque HYDRO - Accueil "Safe" Levels of Arsenic in Drinking Water May Harm Babies and Mothers When researchers from the Marine Biological Laboratory (MBL) and at Geisel School of Medicine at Dartmouth began feeding mice low levels of arsenic considered safe for human consumption in drinking water by the Environmental Protection Agency, they intended to study the heavy metal‘s affect on the immune system and susceptibility to the flu, but they didn’t get that far. The team instead concluded that legal levels of arsenic in drinking water might be harmful to women and children. Pregnant and/or breastfeeding mothers who consumed low levels (10 ppb) of arsenic in their drinking water, the scientists found, exhibited significant disruption in their lipid metabolism, leading to diminished nutrients in their blood and in their breast milk. As a result, their offspring showed significant growth and development deficits during the postnatal period before weaning. The Natural Resources Defense Council summarizes: The arsenic rule has a long and controversial history. U.S.

Renewable Energy and Environmental Sustainability Mission Eau Alsace » Les pesticides ont la vie dure, changeons de culture ! Les océans n'ont jamais été aussi acides Dernières années à vivre pour les coraux? Jeudi, des scientifiques ont déclaré que les océans du globe s'acidifiaient actuellement à un rythme sans équivalent depuis 300 millions d'années, risquant ainsi de venir à bout des récifs coralliens, qui fournissent un habitat à d'autres formes animales et végétales. Il devient plus difficile également aux huîtres et aux moules de construire leurs coquilles, et le développement des micro-organismes dont se nourrissent les poissons est perturbé. Mais les activités humaines, et notamment les combustibles fossiles, ont fait passer la densité de carbone de 280 parties par million (ppm) au début de la Révolution industrielle à 392 ppm aujourd'hui. Au XXe siècle, l'acidification des océans a augmenté de 0,1 unité de pH et les auteurs de l'étude pensent que le pH va augmenter de 0,2 à 0,3 d'ici 2100. L’acidification préhistorique beaucoup moins forte qu’actuellement Les océans s'acidifient lorsque la présence de carbone augmente dans l'atmosphère.

Water Excessive nutrient input to surface water, including nitrate, exacerbates water eutrophication. Clarifying the proportions of different nitrate sources in the aquatic environment is critical for improving the polluted water. However, nitrate sources in river basins are very complex and not clearly understood. In [...] Read more.
