Over the next 18 months Patrick O. Brown, a Stanford University biochemist, will take a break from his normal scientific work (finding out how a small number of genes are translated into a much larger number of proteins) in order to change the way the world farms and eats. He wants to put an end to animal farming, or at least put a significant dent in our global hunger for cows, pigs and chickens. [...more]
Alarmed by a substantial oversight in the global climate talks leading up to the United Nations Climate Change Conference in Copenhagen next month, more than 60 of the world's most prominent agricultural scientists and leaders underscored how the almost total absence of agriculture in the agreement could lead to widespread famine and food shortages in the years ahead.

I gave a talk in South Texas recently on the environmental virtues of a vegetarian diet. As you might imagine, the reception was chilly. In fact, the only applause came during the Q&A period when a member of the audience said that my lecture made him want to go out and eat even more meat. "Plus," he added, "what I eat is my business -- it's personal." [...more]
The number of hungry people, which was declining for several decades, bottomed out in the mid-1990s at 825 million. It then climbed to 915 million in 2008 and jumped to over 1 billion in 2009. With world food prices projected to continue rising, so too will the number of hungry people, leaving millions of families trying to survive on one meal per day. “We know from studying earlier civilizations such as the Sumerians, Mayans, and many others,” says Brown, “that more often than not it was food shortages that led to their demise. It now appears that food may be the weak link in our early twenty-first century civilization as well. [...more]
One way to maximize the eco-friendly factor of a structure is to include a green roof-and this doesn't refer to the paint color. "Greening" a roof, or covering a roof with vegetation, is gaining popularity in North America, where the number of green roofs increased 30% from 2006 to 2007. Benefits of green roofs include improved storm water management, energy conservation, reduced noise and air pollution, improved biodiversity, and even a better return on investment than traditional roofing.

An international team of scientists has proposed a set of basic rules to help save the world’s imperiled coral reefs from ultimate destruction. [...more]
New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. [...more]
The research, led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., suggests that the reduced flows in many cases are associated with climate change, and could potentially threaten future supplies of food and water. [...more]
Bottled water across the country contains a wide variety of toxic substances, according to laboratory tests conducted by the Environmental Working Group (EWG). "Our tests strongly indicate that the purity of bottled water cannot be trusted," the study authors write. "Given the industry's refusal to make available data to support their claims of superiority, consumer confidence in the purity of bottled water is simply not justified." [...more]
Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. A study to be published online March 13, 2009 in Geophysical Research Letters by researchers at the Carnegie Institution and the Hebrew University of Jerusalem warns that if carbon dioxide reaches double pre-industrial levels, coral reefs can be expected to not just stop growing, but also to begin dissolving all over the world.
