Abstract

The 80s showed the world that the human environment has been so destroyed and the growth of the population and the ever-increasing increase in human production power have given such dimensions to this destruction that the habitability of the earth has been threatened and the lives of human beings have been endangered. The researches that took place in this decade and the huge changes that took place in the natural conditions of the earth indicated that the earth is warming. Global warming has brought drought, famine, and water scarcity. The cold and snowy winters of the past are no more. Summers have become hot and long, and also the amount of annual rainfall has decreased. This heat damages agricultural products and causes shortage of water needed for agriculture and drinking water. In addition, the increase in the earth's temperature has endangered the living conditions of many animal and plant species, and a large number of them have disappeared so far. This increase also includes the risk of melting polar ice and icebergs. If this happens, the sea level will rise. As a result, many coastal cities and low-lying deltas of the world will go under water, including the city of Miami in the United States of America and the delta of Bangladesh.
