...nutrient pollution that ends up in the Gulf comes from the hundreds of thousands of farms in the Midwest. The only sure way to shrink the dead zone is to reduce the amount of fertilizer running off those farms. But thanks in part to the push for corn-based ethanol and the skyrocketing price of food crops, U.S. farmers are planting more acres for corn than they have since World War II - including 15 million more acres last year than in 2006. Although there are measures farmers can take to limit fertilizer runoff, those changes are expensive, and there...
...Weighing the consequences of innovation is not a matter of using less or more technology. All students (especially those of you who will soon leave the Yard) must understand the how and why—that means getting your hands a bit dirty. Is ethanol a practical solution to the energy crisis? Is investing in synthetic biology the best (and most ethical) way to cure disease? Should e-voting become standard practice? How do we balance development with sustainability...
...heading off devastating climate change--and to sidestepping out-of-sight oil prices along the way--is to improve technology. We need good alternatives to fossil fuels, not the ersatz variety in which we convert corn to ethanol and then face soaring food prices. We need to harness vast amounts of solar power and start storing the carbon dioxide emitted by coal-fired power plants underground. We need green buildings that demand less energy for heating and cooling, and automobiles that get vastly more miles per gallon...
...part, E.U. Agriculture Commissioner Mariann Fischer Boel protests that biofuels had become a scapegoat. She said that the E.U. uses less than 1% of its cereal production to make ethanol, and while two-thirds of Europe's rapeseed crop is used for biodiesel, this accounts for only about 2% of global oilseed demand...
...target is still attainable and argues that the E.U.'s biofuels policy has had only a minimal impact on world food prices. Mandelson has tried to shift the blame to the U.S. and the subsidies that are driving up to one third of its maize crop into ethanol production...
