Dead zones are created when excess nitrogen and other pollutants in ocean water promote large blooms of algae and phytoplankton on the surface. The nitrogen gets there in a couple of ways: through river water filled with fertilizer from farm runoff and from air polluted with tailpipe and smokestack emissions. When the algae die and sink to the ocean floor, bacteria there break them down, while consuming pretty much all of the available oxygen in the water. The bacteria also proliferate wildly, taking over the ecosystem and exacerbating the oxygen depletion. If conditions like strong currents, which are common...
...from the streets of the capital. During a Sino-African summit in 2006, vehicle restrictions were enacted that removed about 800,000 of Beijing's then 2.8 million cars. The restrictions, which were put in place for three days, were "remarkably successful" and led to a 40% drop in nitrogen oxides, according to a study conducted by researchers from Harvard University and the Royal Netherlands Meteorological Institute...
...billion to $4 billion each. Nippon Steel, Japan's largest steelmaker, introduced a type of eco-friendly coke-making technology called dry-quenching in China that has become widely used throughout the industry. It produces the coke, a form of carbon essential for making steel, by cooling it with nitrogen rather than water, which significantly reduces the amount of carbon dioxide released. The resulting steam is captured and used to produce electricity. Nippon has supplied about 30 of these systems at an estimated $20 million to $40 million each. In 2003, Nippon Steel set up a joint venture with Shougang...
...American Midwest is essentially the granary of the world, supplying corn, wheat and other crops to markets from Chile to China. But all that food doesn't grow by itself. In 2006 U.S. farmers used more than 21 million tons of nitrogen, phosphorus and other fertilizers to boost their crops, and all those chemicals have consequences far beyond the immediate area. When the spring rains come, fertilizer from Midwestern farms drains into the Mississippi river system and down to Louisiana, where the agricultural sewage pours into the Gulf of Mexico. Just as fertilizer speeds the growth of plants on land...
...earlier this year resulted in the removal of some non-cancerous polyps. An examination of his skin in February, which he repeats every few months, discovered on his leg a non-invasive form of skin cancer, called a squamous cell carcinoma, which was "destroyed" earlier this month using liquid nitrogen. It was the fifth incidence of skin cancer for McCain. Only one of those cancers, a 2000 invasive melanoma on his left temple, was considered seriously life threatening. That cancer was removed in 2000, leaving a scar on his face. Connolly said that the chance of that cancer's recurrence...
