Environmental Pollution and ways to Reduce Contamination with use of Environmental Engineering Techniques in Metropolises of Developing Countries

Abstract

Environmental pollution comes from a variety of sources. With the advancement of human civilization and the development of technology and population growth, now the world is facing a problem called pollution in air and land, which threatens the lives of the world's inhabitants. One of the current crises is environmental pollution, which mostly is considered to be the result of the technology, industrial and agricultural development expansion. If there is no control over the Progressive and exponential growth of this phenomenon, we will face an environmental catastrophe and disaster. In a simple definition, environmental pollution is any change in the Features of environmental components, i.e. water, soil, air, etc., so that it is impossible to use them optimally and endangers the lives of living organisms directly or indirectly. Access to healthy and adequate food, drinking water and clean air is the most obvious right of all humans, and the production and provision of these needs for citizens is an inherent duty of all governments. On the other hand, preserving the environment along with agricultural and industrial production activities is very important. The issue of environmental pollution and the creation of a sustainable environment is the main concern of all humans on earth. Fortunately, with the use of biotechnology and the available capabilities in nature, the Environmental damage rate can be minimized. One of the environmental needs around us is to maintain and control it from all kinds of pollution, destruction and misuse of nature. Environmental pollution occurs in various ways which requires the use of new engineering methods to protect and control environmental pollution. Today, environmental engineering and environmental control is one of the key and vital issues in human life. In the present article, the impact of pollution on environmental factors such as climate, sound and noise, traffic, etc. on the environment, as well as ways to reduce pollution with the help of environmental engineering techniques have been studied.
