        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.
