		<description><![CDATA[The common military proverb notes &#8220;there are no atheists in a foxhole,&#8221; during wartime, and apparently to NASA, the entire Earth feels like a foxhole when confronted by a giant asteroid. NASA chief Charles Bolden did not have many reassuring words for the U.S. House of Representative Science Committee when he spoke recently about his agency&#8217;s efforts to track and mitigate recent threats from space. “From the information we have, we don’t know of an asteroid that will threaten the population of the United States,” Bolden said last week. “But if it’s coming in three weeks, pray.” (MORE: It&#8217;s the Little Asteroids That Get You) The series of talks convened by the Science Committee were prompted by recent events that saw an asteroid roughly 50 feet in diameter to explode over Chelyabinsk, Russia on February 15. The blast injured 1,200 people, shattered windows and damaged buildings when it entered the Earth&#8217;s atmosphere and spontaneously combusted. That same day, in a completely unrelated (and this time, expected) incident, an asteroid discovered by amateur astronomers and followed by NASA passed a mere 17,200 miles from our planet – within the orbital belt of geostationary satellites. The asteroid was a near miss, to be sure, but the Russian meteor caused most alarm because it had arrived completely undetected, causing governments around the world to reconsider their asteroid defense programs. Though Bolden did call attention to how unprepared we are with technology to deal from the impact of a collision with a NEO (near earth object), he attempted to assuage fears by noting that the probability of such objects impacting Earth within the next 100 years is “extremely remote.&#8221; The space agency has been documenting and collecting data on NEOs for over 15 years, and it is responsible for the discovery of about 98% of all known NEOs &#8212; a total of about 10,000. (PHOTOS: Russia Meteor Explosion Shatters Windows, Injures Hundreds) But former NASA astronaut and founder of the B612 Foundation (a nonprofit dedicated to protecting Earth from asteroid impacts) Edward Lu, wasn&#8217;t<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=science.time.com&#038;blog=13785469&#038;post=14199&#038;subd=timeecocentric&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>

		<title>Betting on Hunger: Is Financial Speculation to Blame for High Food Prices?</title>

		<description><![CDATA[Correction appended Dec. 17, 2012 Remember the food crisis of 2007 and 2008, when rapid and extreme increases in global food prices led to riots and civil unrest in 28 countries? While we have yet to see unrest on the same level since, the shadow of that crisis, and the debate as to what the systemic causes were, remains. At the end of November, the World Bank warned in its Food Price Watch report that high and volatile prices are the “new normal.” In a world where nearly 1 billion people live in hunger — an estimate that Jomo Sundaram, assistant director general of the U.N. Food and Agriculture Organization (FAO), describes as conservative — high food prices can be fatal. The shift in prices affects consumers in rich countries, who will see their grocery bills rise at a time when wages in much of the world are stagnant. But the real impact is felt by the global poor, in places like Tajikistan, where individuals spend nearly 80% of their income on food. Price spikes in those places can be devastating, even deadly. Prices of agricultural commodities are now 7% higher than a year ago. Wheat and grain prices are especially high, with the former heavily impacted by crop failure in the U.S., Russia and other regions. (MORE: Food Fight! Stores, Producers, Consumers Battle over High Food Prices) There are obvious factors at play here: poor weather, including drought in the U.S. Corn Belt, as well as the growing demand for grain from the biofuel industry and from consumers in places like India and China who are transitioning to a more meat-heavy diet. (It takes more than 15 lb. of grain to produce 1 lb. of beef.) For an increasing number of experts however, these factors do not go far enough in explaining what has caused food prices to spike since the 2000s, reversing what had been a four-decade-long trend of declining prices. Instead, experts are pointing toward financial actors who have increasingly moved into the agricultural markets to bet on future prices<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=science.time.com&#038;blog=13785469&#038;post=12503&#038;subd=timeecocentric&#038;ref=&#038;feed=1" width="1" height="1" />]]></description>
