than plane. If they travel by train or bus‚ they will spend more time on the way. Admittedly‚ with the popularity of cheap air travel‚ more consumption of fuel may lead to pollution of surroundings and degradation of air quality. Pollutants (e.g.‚ sulfur dioxide and nitric oxide) will damage our living circumstance. However‚ any transport tools have fuel consumption. The authorities have taken measures to alleviate this problem. To sum up‚ although there may be some fuel depletion‚ taking the clear

losing these irreplaceable structures forever. Many of these monuments have cultural and aesthetic value that is beyond price. Acid Rain One of the more destructive forms of pollution is acid rain. Acid rain occurs when fossil fuel emissions containing sulfur dioxide combine with moisture in the air to form acidic precipitation. When acid rain falls on historical monuments of limestone or marble ‚ a chemical reaction takes place which has a corrosive effect on these structures. The reaction dissolves the

Also‚ these cars produce significant more amounts of sulfur dioxide compared to traditional internal combustion engines‚ and what about the factories that burn billions of tons of coal everyday to produce electricity to charge these cars? Yes‚ these cars do produce little carbon dioxide directly‚ but the main

Since there is going to be less people in China they won’t need as much water (Doc C). Liu says‚ the population controls have kept sulfur dioxide emissions down by 17.6%‚ and reduced water pollution by 30.8% (Doc C). There are so many people in China they need a way to decrease their population. A whole bunch of people in China died. A devastating famine killed an estimated 30 million

What causes ASS? ASS are any material or sediment that contains iron sulfides that‚ when disturbed or drained‚ forms sulfuric acid. In most cases‚ the iron sulfide present is pyrite (FeS2‚ also known as Iron (IV) Sulfide). This pyrite is very reactive. It is usually the smaller crystals of pyrite found in ASS. The pyrite reacts with oxygen to create sulphuric acid (therefore disturbing the soil creates the acid‚ as the pyrite is exposed to the air). The smaller pyrite framboids (raspberry shaped

of acid rain is‚ however‚ less then 5.0. Major primary pollutants produced by human activity include: * Sulphur oxides (SO4) - especially sulfur dioxide‚ a chemical compound with the formula SO2. SO2 is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds‚ their combustion generates sulfur dioxide. Further oxidation of SO2‚ usually in the presence of a catalyst such as NO2‚ forms H2SO4‚ and thus acid rain. This is one of the causes

do the same with olivine. Also‚ he believes small things could make a big difference. Besides the olivine‚ there is another example of utilizing the geoengineering‚ which is mimicking the volcano. The volcanic eruption will release quantities of sulfur dioxide and the gas quickly formed tiny droplets of sulfuric acid‚ which acted like minuscule mirrors and reflected some of the sun’s rays back into space. Based on this situation‚ there is one another geoengineering approach to reduce global warming

Air pollution is a major problem facing our environment today. This dilemma is harmful to every single living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. How can we limit the effects of air pollution? We all know it affects the environment‚ but it also can affect us directly. Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in
