        An Environment is our surrounding consisting of living and non-living components around us. A balance in the
        environment is essential for the existence of a healthy life on this earth. Humans constantly interact with it in direct
        or indirect ways. Sometimes this interaction is biased and disturbs the balance of this mother earth resulting in
        the changes that affect all. We all need to understand its importance and work in the direction of saving it from
        all possible ways of destruction. In this chapter, we will learn some important facts about our environment and its
        relationship with the society.


                 Environment

        'Environment' word is derived from the French word 'Environia' which means “to surround”. In simple terms, it
        refers to our surrounding consisting of physical, chemical and biological elements that maintain a balance between
        the living and non-living components. It also impacts the growth and development of any life in the surrounding.
        Our environment is classified into two basic categories:


        Natural Environment
        When all living and non-living elements occur naturally in our surroundings and affect a life in its natural ways
        by encompassing interaction of all living species and natural resources, it forms our natural environment. Plants
        and animals living on land, in air or water form our natural environment. Natural Environment is made up of two
        important components:
           • Abiotic: It is the non-living component of our ecosystem. There are five important abiotic factors: sunlight/
          temperature, soil, minerals, wind/air and water.
           • Biotic: It is the living component of our ecosystem. For example, living organisms like plants and animals.

        Man-Made Environment

        It is the environment created by humans to create an atmosphere comfortable for him to interact and adjust to
        the natural environment. For example, permanent human settlements like villages, towns, cities, transport and
        communication facilities, factories, dams, etc.
