Effects of Science and Technology on Society

           
         
             Science and technology may be responsible for many problems that our society faced. The problems are those high-tech weapons,bombs and also those poisonous chemical,which brought us into danger among ourselves and others. In our society today,many of us are so dependent in technology,such as the internet,computers,cellphones and etc. In our environment,one of the biggest problem is pollution. There are three types of pollution,water,air and noise pollution.
                            
Throwing toxic wastes into river
                                     
               Water is one of the resources that we need most,some people can survive without food for more than a week but they cannot survive without water less than a week. According to Water Pollution web site “millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes.” Science and technology causes much water pollution, such as throwing toxic waste into rivers, seas, and even small creeks. For example, many factories are using toxic materials to produce a product,in disposing there toxic wastes they throw it in rivers, seas, and even small creeks because it is not hassle. 
Factories are the commuters of air pollution

and also vehicles
              
                 The air that we breath everyday to keep us alive, if there is no air,there is no human or other living creatures can live. According to Air Pollution and Respiratory Health web site, “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.” We all know that air pollution cab cause many health problems. The advancement of science and technology not only causes us health problem but it also destroying our ozone layer and cause us global warming. According to Air Pollution web site "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 been depleted the ultraviolet light will go through and can cause us skins cancer."
Sound give's  pleasure to man
and also give pollution to our environment
like the sound of the airplanes and cars
             
                 Sound are very commonly use in our life. It can give us pleasure such as when we listen to a music, or listening to the nature. It also can be use 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 wrong with it. But in the modern society many sound can be annoying and unpleasant, and it called noise. As more science and technology are being develop the more the country are being industrialize. More factories and business are being built. More airports more vehicles and more trains are being made. Those are the many causes of noise pollution. The more the country are being industrialize 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 affect the workers it also affect those who live around it. 
              
                The advancement of science and technology affected us in many negative ways in term of destruction and pollution. The more machinery and technology we built the more resources we need. The more natural habitat will be destroy so people could get those resources, and the natural habitat is to help us from polluting the air and protect our ozone. So science and technology are responsible for many of the problems that face us today.
