...thousand cases worldwide per year; and, if detected early, the disease can be treated effectively with antibiotics. But since the early 1990s, plague has returned to places - including India, Zambia, Mozambique, Algeria and parts of China - that had not seen it in many years or even decades. Its global footprint has also shifted, according to a paper published last month in the journal PLoS Medicine. In the 1970s, most plague cases were in Asia; today, more than 90% are in Africa. The conundrum for epidemiologists: Why is human plague reappearing now, even though nearby animal populations have likely harbored...
...pause, which could last up to several months, would be designed to ensure that the smaller U.S. footprint in Iraq doesn't embolden insurgents to reignite the civil war that ripped the country apart in 2006 and the first half of 2007. The U.S. military is counting on the growing Iraqi security forces to fill the gap left by the U.S. withdrawal, but wants to test that hypothesis by removing its own forces in increments...
...trails, the ecosystems destroyed by artificial snow and the energy-hungry lifts, snow machines and hotels that are an integral part of a skiing holiday. Not to mention the miles in the SUV to get everyone there. Ski resorts by their very nature have a pretty big carbon footprint. They are also an industry that takes a direct hit from global warming. According to the Swiss Federal Institute for Snow and Avalanche Research, based in Davos, rising temperatures are leading to changes in snowfall patterns: Alpine areas below 1,600 m (5,250 ft.) now receive 20% less snow than...
...food—particularly red meat—at bargain prices, if you consider the negative externalities involved in its journey from pasture to plate. Imagine that quarter-pound of brisket you ate last night: a widely quoted recent study in the Animal Science Journal shows that the carbon footprint of that beef is 4.11 kilograms, the amount released in about ten miles of driving in an average American car. What if you and thousands of others at Harvard took just a tenth of a pound more brisket than you managed to eat—you might as well have...
...months of 2007 was 3,235 sq. kilometers (1,250 sq. miles or about the size of Rhode Island), a rise from the previous year's figure and alarming because deforestation normally drops in the final rainy months of the year. In a world panicked by its own carbon footprint, the forests of the Amazon are the planet's largest absorber of carbon dioxide...
