environment is the place where we live.it not
only consists of human beings but also tiny creatures , animals , birds , trees
, water bodies , deserts etc.we can call it nature as well.
let me talk about the
state of environments just a few years ago.
at that time ,
environment was full of greenery.flowers were seen even on grasses.trees were
full of leaves.there was almost no dead tree.fresh air blew day and night.birds
sang in the morning with their beautiful voice.people enjoyed the bath in the
open streams.the day of every living being was just fantastic.
now , let me talk
about today;s environment.
alas , today's
environment has nothing but a large amount of dirt and dust.in villages there
are still ponds and streams present but in cities there is no trace of
them.people are cutting trees for their need.we are destroying the atmosphere
by the gases of our vehicles.we dont even try to plant some trees.we just live
our life but a life full of disease.our day always ends with great stress.
so , there is just a
single way to save our beautiful environment.lets wake up and devote a bit time
in planting a few trees , water them and use our feet to walk small
distances if possible.
Environment means the surroundings. Land, water, air, plants, animals, solid wastes and other things that are surrounding us constitute our environment. Man and environment are closely intertwined with each other, to maintain a balance or equilibrium in nature.
Different groups of people working in different areas express it in various ways. When physical scientists talk about environment they generally refer to the physical environment that comprises the three inter locking systems the Atmosphere, the Hydrosphere and the Lithosphere.
Biologists often refer to biological environment consisting of all living organisms of the Biosphere. Similarly social scientists refer to the social, cultural, economic and organizational environment.
Hence environment may be defined as "the sum of all social, cultural, economical, biological, physical and chemical factors surrounding the 'man' to give necessary protection to him."
Two types of environment we may come across. One is the natural environment of the air, water, solid wastes, noise, radiation, soil, timber, wildlife and living space etc. The second one is the man-made environment that deals with work environment, housing, technology, aesthetics, transportation, utilities, settlement, urbanization and so on.
These environmental components are considered as the resources and are mostly exploited and utilized by the men to fulfill their basic physical needs they can be considered as the fellow members of the global eco-system with which men establish emotional, intellectual, or physical relationships and these provide the basis for a sense of purpose of life to them.
Thus, man is firmly placed as an important part of the global ecosystem, which depends on him much as he depends on it. Hence, there is a close relationship between man and environment.
