Their company, Aresa, a Copenhagen-based biotech start-up, has genetically modified a common weed called thale-cress so that its leaves turn red when the plant comes in contact with nitrogen dioxide--a compound that naturally leaches into the soil from unexploded land mines made from plastic and held together by leaky rubber seals. Aresa is growing large patches of the stuff on old army shooting ranges that have been seeded with land mines...
...water was murky grey and appeared to contain everything from household garbage to industrial sediment and waste. And it’s really no surprise, since environmental regulations do little to prevent the dumping of waste into water bodies by factories and farms, including everything from petroleum to ammonia nitrogen to mercury. Since China has only one-fifth the water supply per capita as the U.S., conservation and stricter regulation is essential in order to preserve a sustainable water supply...
...ease the environmental impact of coal power by using clean-burning technology and by encouraging energy conservation. EVN has launched a rebate campaign promoting power-saving fluorescent lightbulbs; Vietnam recently passed a clean-air law that requires new coal plants to install filters for toxic sulfur dioxide and nitrogen. In Uong Bi, EVN installed filters on the new generator's smokestack - a measure that tea-shop owner Dang says has reduced the black smoke. But even the most advanced technologies can't cut CO2 emissions by much. Carbon sequestration - a proposed method of fighting global warming that siphons off carbon...
...have seen firsthand how Mbola's farming households suffer from a recurrent drought--not of water but of nitrogen and other nutrients needed to achieve a decent harvest. Previous harvests have exhausted the soil because Mbola's farmers could not afford chemical or organic fertilizers...
Still on the cutting edge of chemistry research, Schrock reduced nitrogen gas to ammonia in his lab four years ago, the first time such a reaction has been carried out artificially...
