...estimates that every kilowatt-hour ofelectricity saved prevents the emission of 1.5pounds of carbon dioxide, 5.8 grams of sulfurdioxide, and 2.5 grams of nitrogen oxides. Thesethree gases comprise the bulk of air pollution
...mechanics and science behind Otisca are clear and simple. Its advantages in terms of transportation and use in various engines, including diesels and turbines, put it in direct competition with oil and gas. Coal's chief disadvantages are that it is bulky and dirty. Sulfur oxides (SOx) and nitrogen oxides (NOx) have been indicted as principal villains in the formation of acid rain. More than half the nation's electricity is produced by power plants that burn coal. By running finely ground coal through a chemical bath (currently pentane, a hydrocarbon similar to butane), the Otisca process separates...
...Midwest, California's Regional Clean Air Incentives Market program (RECLAIM) is the most ambitious attempt so far to cut urban air pollution. Under the plan, businesses will be issued shares in the region's overall emissions, and together they must reduce smog-forming hydrocarbons by 5.8% a year, nitrogen oxides by 8% and sulfur dioxide by 8.5%. Companies that exceed the reductions can sell emission "credits" to other firms. The market covers 2,800 businesses that account for one-fourth of the pollution in Los Angeles, Riverside, San Bernardino and Orange counties...
Trees normally get their nitrogen from the ground and convert it to protein. When tree leaves fall onto the ground, they are decomposed by microorganisms into nutrients and nitrogen, which are then reused by the trees the following season...
Secondly, Bazzaz has shown in experiments that butterfly larvae that eat leaves with a higher carbon-to-nitrogen ratio than normal are more prone to death. They have a higher mortality rate and grow less than larvae that eat leaves grown from a nitrogen-rich environment. Consequently, insect populations will go down, which in turn may upset the food chain...
