Carbon dioxide, which is emitted largely by combustion of fossil fuels, is the most influential human-made greenhouse gas. ... In 1997,160 nations reached an agreement concerning the use of fossil fuels and the emission of CO into the earths atmosphere. ...
These forests provide habitat for an estimated half of the world's plant and animal species, provide water and fuel for much of the world's population, and influence regional and global climate. Commercial logging, clearance for agriculture, ranching, and fuel gathering are all responsible for the destruction. ... Solutions include the development of alternative fuel wood supplies through fuel wood plantations, the regulation of logging, and a consensus as to the value of forest conservation over commercial development. ... The primary conservation concern here is with fossil fuel...
The EPA states that fossil fuel-fired electric utility plants are responsible for 70 percent of the annual SO2 and 30 percent of NOX emissions in the United States. ... To achieve this goal, two phases of restrictions would be placed on fossil fuel-fired power plants. ... Under the Acid Rain Program's free-market based approach, individual utility units are given allowances or "credits" based on historical fuel consumption and emissions data. ... A source may opt to reduce its SO2 emissions by switching to a cleaner fuel, redirecting operations to cleaner units, or reducing output...
Fossil fuel energy is a prime resource used. Nearly 80 per cent of the world's fossil energy used each year is used by the developed countries. Because fossil energy is a finite resource, its depletion accelerates as population needs escalate. ...
Cars and Acid Rain On freshly painted vehicles damage to automotive paints and other coatings can happen. It is mostly on dark colored vehicles, and the only way to spot it is under fluorescent lamps. Most damages are caused by environmental fallouts, whether it is acid rain, bird dropping, poll...
Sulfur and nitrogen oxides (often abbreviated SOx and NOx, respectively) are common by-products of fossil-fuel combustion. SOx forms from sulfur impurities in fuels, especially coal and some petroleum products. NOx forms from nitrogen impurities in fuels and from nitrogen in the air used for combustion. ... In some areas of central Africa, use of heavy fuel oils to generate electricity produces acid rain. ... Since passage (1970) of the Clean Air Act, U.S. emissions of sulfur dioxide have been reduced substantially, due to the burning of low-sulfur oil and coal, installation of costly scrubber...
These pollutants come from the burning of fossil fuels, such as coal, natural gas, and oil, and from certain kinds of factory distributions. ... Nitrogen oxides are released into the air by burning fuels such as gasoline and coal. ... Motor vehicles, industries, burning coal, gasoline, other fossil fuels; along with chemicals that are in hairspray and paints release ozone. ... Particulate matter (PM), little particles of pollution, are released by cars, trucks, and buses that are burning diesel fuel, fertilizers, pesticides, road construction, steel making, mining, and turning on fire places...
Carbon dioxide, nitrous oxide, and methane (CH4) are produced by the burning of fossil fuels, expelled from living and dead biomass, and released by the metabolic processes of microorganisms in the soil, wetlands, and oceans of our planet. ... Lead compounds, which are emitted by motor vehicles fuelled with leaded petrol, are cumulative poisons. ...
Acid rain or acid precipitation is the rain, snow, fog hail which has pH levels below 5.6, the average acidity of rain. The pH scale is used to measure the level of acidity by measuring the hydrogen ion concentration, were pH 1 is the strongest acid and pH 14 is the strongest base. Acids and bases o...
Unfortunately, both CO2 and N results from human activities such as the combustion of fossil fuels in vehicles, power plants, industries Together they alter climates to extremes, contribute to the formation of acid rain, attributes to soil infertility, as well as producing low level photochemical smog; affecting the Earth's ecosystems respectively. ...
Review the effect of acid rain on the local distributions of fish and aquatic invertebrates. What are the biological reasons for the disappearance of these animals as pH falls? Humans produce about 160% of the natural emissions of sulphur. This is compared with about 5-10% in the case of carbon...
Despite these natural occurrences, the burning of fossil fuels (such as coal and oil) can be largely blamed for the emissions. ... S (in fossil fuels) + O2 =* SO2 2 SO2 + O2 =* 2 SO3 Much of the sulfur dioxide is converted to sulfur trioxide in the atmosphere SO3 + H2O =* H2SO4 The sulfur trioxide can then dissolve within water to form sulfuric acid Nitric oxide and nitric dioxide are mainly from power plants and exhaust fumes. ...
