Colombia has shown a strong commitment to the achievement of the Convention on Biological Diversity's2010 biodiversity target, by promoting the conservation...
Key component of China's pollution problem: Scale of nitrogen's effect on people and ecosystems reveal
2013-02-27 02:46:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: It's no secret that China is faced with some of the world's worst pollution. Until now, however, information on the magnitude, scope and impacts of a major contributor to that pollution -- human-caused nitrogen emissions -- was lacking. A new study co-authored by Stanford Woods Institute biologist Peter Vitousek reveals that amounts of nitrogen (from industry, cars and fertilizer) deposited on land and water in China by way of rain, dust and other carriers increased by 60 percent annually from...

Mongabay: The world's largest river system is being rapidly degraded and imperiled by dams, mining, overfishing, and deforestation, warns a study published last week by an international team of scientists. Writing in the journal Conservation Letters, researchers led by Leandro Castello, a research associate at the Woods Hole Research Center, catalog the litany of threats facing the Amazon river and its tributaries. They note that existing terrestrial protected areas may not be enough to protect river ecosystems...
