Good morning to the Excellencies, my respected teachers and my dear friends. The topic of my speech is Environment. Environment is the surrounding in which we live. It is the source of life. Our whole life is dependent to the environment. It directs our life and determines our proper growth and development. Good or bad quality of social life depends on the quality of our natural environment. The need of human beings for food, water, shelter and other things depends on the environment around us. There is a balanced natural cycle exists between environment and lives of human beings, plants and animals. Human society is playing vital role in degenerating the natural environment which in turn negatively affects the lives on this planet. All the human actions in this modern world directly impact the whole ecosystem.

We live on earth in different types of surroundings. This surrounding is our environment. We eat, breathe, clothe ourselves, reproduce and then die. The next generation comes and the cycle goes on; and the human race flourishes on earth. The physical environment on the earth provides favorable conditions for the existence and growth of different life forms, including man. These living beings constitute the biological environment. Both the physical and biological environments are in a close interaction with each other and form a stable self perpetuating system. In prehistoric days man lived in harmony with nature but in the course of his evolution man has developed a new type of environment, the man-made environment.
