...have found the first physical evidence of chemical weaponry, dating from a battle fought in A.D. 256 at an ancient Roman fortress. James concluded that 20 Roman soldiers unearthed beneath the town's ramparts did not die of war wounds, as previous archaeologists had assumed, but from poison gas...
...recent bombardment of Gaza, not far to the south of ancient Tyre. A Chinese ruler in A.D. 178 put down a peasant revolt by encircling the rebels with chariots heaped with limestone powder. Accompanied by a cacophonous troupe of drummers, the charioteers pumped the powder into a primitive tear gas even more corrosive and lethal than its modern equivalent.

...hybrid. Practically speaking though, there is a faster and cheaper option: shift to a low-carbon diet. The meal plan of the average American family accounts for 2.8 tons of CO2 emitted annually, compared with 2.2 tons for driving. Worldwide agriculture contributes some 30% of global greenhouse-gas emissions, far more than transportation. So when it comes to cutting your carbon footprint today, the truth is that what you eat is as important as what you drive. "If you can't buy a Prius," says Jonathan Kaplan of the Natural Resources Defense Council, "you can certainly eat like...
...reared on grain and loads of it--670 million tons in 2002--and the fertilizer used to grow that feed creates separate environmental problems, including surface runoff that leads to dead zones in coastal waters like the Gulf of Mexico. Those grain-fed cattle then belch methane, a greenhouse gas that is 20 times as potent as CO2. "Reducing beef is the first step to a green diet," says Michael Jacobson of the Center for Science in the Public Interest (CSPI...
Even oil- and gas-rich states are panicking. In Alaska, for instance, sinking oil prices have some state legislators scrambling to lock in education budgets for the next few years as the state prepares to dip into its savings to cover a shortfall of approximately $1.65 billion this year and up to $3 billion next year. In Montana, which earned big bucks last year from its natural resources, education is funded primarily through property taxes, and many fear that the closing of mines and aluminum plants could trigger a mass exodus and redistribute the tax base. "It doesn't look...
