What is the first thing that people ought to do in face of pollution, according to the author? [br]
The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun through all the layers of pollution within the air? Not only are beautiful sights such as this hidden behind the pollution this world causes everyday, but an increase in diseases, infections and death occurs. What causes pollution? What can we do to prevent it, and get rid of it? Is it fair to the children of the future to have to suffer the consequences that pollution causes? Why not take care of the problem now? Factory and business owners have the ability to prevent air pollution. Air pollution is the presence in the atmosphere of harmful gases, liquids, or solids. Air pollution, known as smoke pollution for many years, resulted from coal combustion. smog has been a problem in coal-burning areas for several centuries. smog finally decreased when coal combustion was replaced by oil and gas combustion. Air pollution is caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb stmlight which reduces visibility. Particles also reduce visibility by attenuating the light from objects and illuminating the air causing the contrast between the objects and their backgrounds to reduce. Not only does it effect visibility, but it hastens the erosion of building materials and the corrosion of metals, interferes with the human respiratory system, and brings toxic materials into the body. The small particles cause chronic bronchitis, bronchial asthma, emphysema and lung cancer. The second type is sulfur oxides which come from the burning of coal and industrial processes. Damage to materials, to vegetation, and to the human respiratory system are caused by the acid nature of oxides. small quantities of sulfur oxides can increase illness and mortality. The third type of pollutant is carbon monoxide. Carbon monoxide is a colorless, odorless, tasteless gas against which humans have no protection. Carbon monoxide comes from the exhaust of gasoline-powered vehicles and secondarily from industrial processes.
