Importance of Environment| And A Need for Its Conservation
Environment is the key for existence of life on the earth. But there is drastic environment change due to global warming, excessive pollution, industrialization etc.
The natural environment is a gift of nature and we need to conserve it for the benefit of life in future.
Importance of Environment for life
Hence, even scientists are working on only Mars to create life on it as it has some suitable environment. This shows the importance of environment for life & existence.
So below we will see the importance of environment for various roles in life.
For healthy living: To have a healthy life one needs fresh air (free of pollution), clean water supply and tidy surroundings. If air and water are polluted and surroundings are filthy then we are prone to fatal health disorders. So we need to safe guard environment in terms of pollution and disposal of garbage.
Better breath: All living things breathe air for survival. The air mostly composes of nitrogen, oxygen, carbon-dioxide and other gases. Of them oxygen is the key for the body as it helps in generation of energy from the food consumed with the help of mitochondria. So fresh air is an important component in the importance of environment which has to be kept pollution free.
Better water: Water comprises nearly 80% of total body mass. It is the medium for all the reaction and physiological processes in the body. If the very water is contaminated by filth or toxins or even disease causing microbes like bacteria, then that water is a great risk to drink.
Better rainfall: Rainfall is one of the steps of water cycle on the earth. Without rainfall there will be no water on the earth (other than sea water which is unfit to drink). This rainfall depends on tress and green vegetation around to shower as the clouds need to be cooled to form droplets. The presence of plants, trees and greenery is essential in the environment for rainfall, fresh air and water.
Better soil: Soil is the other components of environment. Soil is useful for growth of plants which are again a source of food to the animals around. This soil top layer are good for plant growth and seed germination. Further it is a great
natural resource for many medicines, metals, chemicals etc. So we need to conserve soil for better environment.
Better plants: Plants and trees are also key in importance of environment. Plants which include trees, shrubs, bushes and even small grass help in purifying air as they generate oxygen and take up carbon-dioxide. Thus they keep oxygen levels in the air at optimum and also decrease the global warming component of air i.e. carbon dioxide.
Importance of Environment for humans
For food: Food materials are obtained from plants, animals and natural sources. We obtain carbohydrates, fats, proteins from plants. From animals we obtain meat (protein), milk, eggs (birds), honey (bees).
For shelter: The required building material including furniture is obtained from the environment around.
For clothing: The clothing requirements like cotton fibers, wool, jute are provided from plants and animals.
For furniture: Though we have plastic and artificially made furniture, nothing can replace furniture from environment like wood, porcelain, china clay etc.
For medicine: We obtain many medicines from nature like from medicinal plants, animals (cod liver oil) etc. These medicines are compatible to humans with minimal or no side effects than artificial drugs.
Importance of environment for Health.
Stress free: A healthy environment is good for stress free life. A person in sitting in an office or closed room is prone to more stress than the one working in open environment like farms, seashores etc. Hence we see many educational institutes and research institutes are built amidst environment away from the noisy city. In healthy environment there is less pollution of all sort (air, sound etc) so there is good for health due to abundant fresh air and low toxins and irritants.
Pleasant living: To those who wish to live a pleasant life, it is better to build a home in places of environmental bliss like seashore or in between farms etc. One experiences peace of mind, low disturbance in mood in such places.
Prevent spread of diseases: There is very much chance for spread of diseases in closed environments where there are many people confined to small space. Many epidemic diseases spread fast in such places.
Considering the importance of environment with reference to above points everyone has to take a precaution to minimize waste by careful use of power, automobiles and other pollution generating agents.
