What a World, We Need to Keep it
Air Pollution is not a new topic. It is a problem that we have noticed since the industrial revolution, when trees, houses and cars were covered in soot from the factories. People demanded change then, just as they are demanding it now. With all the talk of acid rain, global warming it seems hopeless, but it isn't. Everyone can make a difference. After reading this you will understand the causes, effects and possible solutions to the problems of acid rain and global warming. You will also see that things are bad but not hopeless.
Acid Rain is the term given to any precipitation that is above normal acidity, this includes snow and fog. The acidity or causticity of a solution is measured in pH. This very highly acidic rain kills plants and animals and destroys buildings. Acid rain occurs when the moisture in the air mixes with Carbon, Nitrogen, and Sulphur gases. These gases are released into the air by the burning of fossil fuels (natural gas, coal and oil). The primary source of the gases comes from electric companies that burn coal. Damage caused by acid rain is tremendous. The acid in the rain bonds with the minerals in the soil, tying them up so that plants can not use them. The plant becomes mineral deficient and weak. This is a major agricultural problem. The rain effects lakes, rivers and the animals living within them. Many architectural structures are destroyed from the acid rain. Most of the cement used to make our buildings are made from lime which is very reactive with acid. You can see the effects of this weathering if you look at old gravestones or statues. Industry is looking for solutions to the air pollution problem. The best solution would be to stop burning fossil fuels all together but at this time we have no other alternatives. Scientists are trying ways to cut down on pollution. One way is to wash the coal before they burn it. Washing it takes off most of the sulfur but not all of it. The rest would have...
