...same as they are in the U.S. In countries like India, for example, leaded gasoline is still commonly used in cars (in the U.S. it was replaced by unleaded fuel in the 1970s), and the lead from car exhaust can seep into the ground, saturating the soil in which food plants, including those that are dried and ground into spices, are grown. Such environmental exposure is the most likely source of lead in the products they tested, say the authors...
...year. It's less popular in other coal-rich spots such as Texas, where the coal is deeper underground and requires a different kind of mining to unearth. Coal companies say mountaintop mining is also cheaper than traditional mining: rather than burrowing under or digging through the "overburden" (the soil, trees and rock that lie on top of coal seams), which requires lots of manpower and expensive machinery, all you need to hit black gold in Appalachia are some explosives...
...access to nature. However, its use affects everyone. For example, unless an area is specifically regulated, someone can clear-cut a hardwood forest in a developing nation for the timber. But losing that forest also means the loss of habitat for wildlife, other forest products for food and shelter, soil fertility - plus numerous other functions, including climate regulation, which are not yet completely understood.

...that warmer water pouring into the sea from Siberia's north-flowing rivers have raised the sea-bottom temperature to the point where the methane, much of it stored under pressure in the form of methane hydrates, can begin to break free. Unlike the permafrost on land, says Shakhova, soil under the sea floor is always hovering at close to the melting point because of its proximity to unfrozen seawater. Anthropogenic (that is, human-caused) warming may be the last straw...
...Counterterrorism experts say the trial confirmed for the first time the existence of an IJU cell on German soil. "The IJU showed it was determined to plot terrorist attacks in Europe," says Guido Steinberg, an analyst at the German Institute for International and Security Affairs in Berlin. And, according to Steinberg, the number of homegrown extremists has only increased since then. He estimates that in 2009, around 40 jihadists traveled from Germany to terrorist training camps in Pakistan. "The challenge for the German authorities is to reach out to these young men and small Islamist groups as early as possible...
