Science and technology may be partly responsible for many of the problems that face us today. The problems are the advancement of weapons, bombs, biochemical and nuclear weapons, which brought us violence amongst ourselves and others. Another problem is human dependence on technology, such as the internet, computers, cell phones, etc. Yet one of the biggest problems is pollution. Three types of pollution that dominate are water, air, and noise pollution.
Water is one of the several resources that we need most, many people can survive without food for several weeks but they cannot survive without water for less than a week. According to the Water Pollution website, “millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes.” The advancement of science and technology causes much water pollution, such as dumping toxic waste into rivers, ponds, oceans, and even small creeks. For example, many Third World countries that are trying to get their country industrialized lack the funds to dispose of their wastes probably. But instead, they dump their toxic pollutants into surrounding bodies of water. All of the toxins that they dump can be washed out into the rivers, seas, or oceans can contaminate the water we use every day to wash our face, hands, clean our dishes, and much more.
The air that we breathe every day to keep us alive, imagine if the air is been polluted through our industrial every day. According to Air Pollution and Respiratory Health website, “In 1991 American industry emitted more than 2.4 billion pounds of toxic pollutants into the atmosphere. In 1991, 98 areas exceeded the Environmental Protection Agency's recommended levels for ozone, and an estimated 140 million Americans lived in those areas.” Of all those pollution in the atmosphere and over thousand, even hundred of thousand as breathing it every day it can cause many health problems to a lot of people. The advancement of our industrial not only causes us health problem only but also depletes our ozone and cause us global warming. The technologies that we build some of them which contain CFC Chlorofluorocarbon, a compound consisting of chlorine, fluorine, and carbon, CFC are commonly been used in refrigerators, solvents, cars, and many more. The CFC can break down by strong ultraviolet light in the stratosphere and release chlorine atoms that then deplete the ozone layer. If the ozone layer is depleted the ultraviolet light will go through and can cause us skins cancer.
Sound is very commonly used in our life that we often overlook all that it can do. It can give pleasure such as when we listen to music or listening to nature. It also can be used as a communication tool, for example when we hear a siren is to let us know to be alert. For engineering, it can be a tool to help them in their job for example mechanical engineering listening to the sound motor of a car to figure out what is wrong with it. But in modern society, many sounds can be annoying and unpleasant, and it is called noise. As more science and technology are being developed the more the country is being industrialized. More factories and businesses are being built. More airports more vehicles and more trains are being made. Those are the many causes of noise pollution. For example, the modern large planes have been changing from a pure jet engine to a fan jet engine which decreases the amount of noise they made. However as the quieter, the planes get the more the airports grow, it will become busier and handle more planes every day. Many people live near the commercial and military airports, imagine that planes fly over your neighborhood every night and make annoying noises that could wake you up from your sleep. For many people who live around those neighborhoods, even though they have moved to somewhere else but that noise still affected them and awoke every night. The more the country are being industrialized the more factories and building are being built. Industrial noise comes from either establish of a factory or by building works. The noise not only affects the workers it also affects those who live around it.
