The environment is the surroundings or conditions in which a person, animal, or plant lives or operates. Environment plays an essential role in the healthy living of human beings. In widespread usage, for some people, the term 'environment' means, only, 'nature'. It matters because it is the only home that humans have, and it provides air, food and other needs. Humanity's entire life support system depends on the well -being of all the environmental factors. Environment mainly consists of atmosphere, hydrosphere, lithosphere and biosphere. But it can be roughly divided into two types such as (a) Microenvironment and (b) Macro environment (c) Physical environment refers to all abiotic factors or conditions like temperature, light, rainfall, soil, minerals etc.
