Scientists considered climate change and indiscriminate use of fire to calculate that deforestation rates ranging from 20 percent to 25 percent could turn Amazon's hydrological cycle unable to support its ecosystem.
When cattle congregate, they're often cast as the poster animals for overgrazing, water pollution and an unsustainable industry. While some of the criticism is warranted, cattle production -- even allowing herds to roam through grasslands and orchards -- can be beneficial to the environment as well as sustainable.
A cheap, safe and effective method of dealing with harmful algal blooms is on the verge of being introduced following successful field and lab tests.
Environmental policy guided by science saves lives, money, and ecosystems. So reports a team of eleven senior researchers in Environmental Science and Policy. Using air pollution in the United States as a case study, they highlight the success of cleanup strategies backed by long-term environmental monitoring.
Leading scientists and other experts from around the world will convene for eight days with policymakers from more than 115 countries to finalize landmark reports on biodiversity, nature's contributions to people and issues of land degradation and restoration. The sixth session of the Plenary of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (#IPBES6), chaired by Sir Robert Watson, begins Saturday at the Intercontinental Hotel, Medellín, Colombia.
One of the key ways to combat global climate change is to boost the world's use of renewable energy. But even green energy has its environmental costs. A new approach describes just how hydropower measures up when it comes to land use effects.
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.
The impacts of global warming are felt especially in mountainous regions, where the rise in temperatures is above average. The repercussions of these changes are manifold and varied, from retreating glaciers to an increase in the frequency and intensity of snow avalanches. Researchers from the University of Geneva, Switzerland, has employed dendrochronology- the reconstruction of past disasters as recorded in growth series of trees- to disentangle the role of global warming in the triggering avalanches.
An estimated 1 billion people do not have access to clean drinking water, a problem expected to worsen with climate change, according to the World Health Organization. In addition, higher energy needs and increased use of heavy metals in industrial processes have increased human exposure to these toxic materials from drinking water in recent decades. Researchers now report in ACS Central Science a new material that can remove heavy metals and provide clean drinking water in seconds.
Since the Flint Water Crisis in Michigan, concern in the US over lead in drinking water has increased. Information about water from private wells has been limited because such wells are exempt from the 1974 Safe Drinking Water Act, the 1986 Lead Ban and the 2011 Reduction of Lead in Drinking Water Act. Now, researchers report a case study in ACS' journal Environmental Science & Technology that sheds some light on the hidden health risks.
