...boiling the planet - but also that science can save us, that we can innovate our way to sustainability. He acknowledged that the developed nations that made the mess can't tell the developing world not to develop, but he also warned that China is on track to emit more carbon in the next three decades than the U.S. has emitted in its history; that business as usual would intensify floods, droughts and heat waves in both countries; that greenhouse gases respect no borders. This earth, he concluded, is the only one we've got; it would be illogical and immoral...
...food sources. Dwarf goats in particular have been a point of contention. They smell bad and can wreak havoc if they escape, opponents say; some also worry that allowing goats will pave the way for legalizing llamas and cows in cities. Goat advocates, who note that only horned males emit musk, say the ruminants are gentle enough to be walked on a leash and that they generate high-quality manure, which can be used as fertilizer...
...though, Waxman-Markey puts a cap on almost all of the greenhouse-gas emissions produced by the U.S. economy - everything from utilities to industry to transportation - setting a limit on how much carbon the country can produce. Industries are issued allowances each year that give them the right to emit a certain amount of carbon; they have to reduce their emissions to meet the cap, or buy allowances from other companies if they exceed the cap. (Companies will also have the option to buy carbon offsets, which involve investing in projects that reduce carbon, like tree-planting.) The idea...
...wind, along with low-carbon sources like nuclear and even coal with carbon capture. That will require plenty of hard scientific research to bring down the price of renewables - they have to be competitive not just in the U.S., but in countries like India and China, which will emit the vast majority of new carbon emissions in the future. "This legislation will finally make clean energy the profitable energy," said President Obama before the bill's passage - but that doesn't seem to be the case...
...city streets once swarmed with bicycles, they are now full of automobiles. Cars clog intersection and expressways. Their exhaust clouds the sky and the air is full of the sound of horns. But zipping through the congestion is the vanguard of another transportation revolution: vehicles that use no gas, emit no exhaust and are so quiet they can surprise the unwary pedestrian...
