Latest Eutrophication Stories
Billions of people owe their lives to nitrogen fertilizers — a pillar of the fabled Green Revolution in agriculture that averted global famine in the 20th century — but few are aware that nitrogen pollution from fertilizers and other sources has become a major environmental problem that threatens human health and welfare in multiple ways, a scientist said here today.
Nitrogen pollution in our coastal ecosystems, the result of widespread use of synthetic agricultural fertilizers and of human sewage, leads to decreased water transparency, the loss of desirable fish species, and the emergence of toxic phytoplankton speciesâ€”such as the algae behind the renowned "red tides" that kill fish.
An international study published today warns that nitrogen pollution, resulting from industry and agriculture, is putting wildlife in Europe's at risk.
Reactive nitrogen compounds from agriculture, transport, and industry lead to increased emissions of the greenhouse gas nitrous oxide (N2O) from forests in Europe.
A major new study finds that nitrogen pollution is costing each person in Europe around Â£130 - Â£650 (â‚¬150 â€“ â‚¬740 Euros) a year.
The growing world population relies on the help of nitrogen for our food supply, yet its very use pollutes the air, soil and water.
Recycling manure is an important practice, especially for large livestock producers.
People who want to eat healthy and live sustainably have a new way to measure their impact on the environment: a Web-based tool that calculates an individual's "nitrogen footprint."
Recalculating the global use of phosphorous, a fertilizer linchpin of modern agriculture, a team of researchers warns that the world's stocks may soon be in short supply and that overuse in the industrialized world has become a leading cause of the pollution of lakes, rivers and streams.
Continued eutrophication of the Baltic Sea, combined with an ever thinner ozone layer, is favoring the toxic cyanobacterium Nodularia spumigena, reveals research from the University of Gothenburg, Sweden.
