Introduction:
If a person is sitting inside a room then all the things, either living or nonliving, that have surrounded him is counted as the environment of that room, same as this earth is full of living or non living organism which are the part of environment. Human, plants, animals, birds, weather, wind, sunlight, sand, soil, land, water, coal, wood, fuels, fire, minerals, etc are the parts of environment which are essential for existence of life on earth.
How it builds?
As we all know, this earth is made of four different spheres biosphere, lithosphere, atmosphere and hydrosphere in which hydrosphere is the largest part on earth among all. All the spheres contain some of the natural resources inside its category:
- Atmosphere: Air, sunlight, weather, etc.
- Lithosphere: Solid or rigid area of the earth, also we can say that the crust and the upper mantle of the earth like land.
- Biosphere: Biosphere is the area or zone of earth where life exists in form of plants, animals, birds and human.
- Hydrosphere: The largest portion (about 75%) of the earth area where water is found in form of oceans.
Life on earth is possible due to some kind of action and reaction between different kinds of resources that are available under environment.
Major factors regarding environment:
- Environment consist different natural resources of air, water, land, soil, plants, sunlight, wind, coal or minerals that are useful and essential for the human life.
- Oxygen is highly needed for taking breath and plants produce oxygen by absorbing carbon dioxide.
- From tree, we also get food, cotton and wood, those are the basic requirements of human life.
- For agriculture, we need natural resources of land, sunlight and water.
- Fresh water is used for drinking, cleaning, wiping, agriculture and manufacturing plants.
- Coal, gases and fossil fuels are used for generating electricity.
Above are some of the major facts about different resources of environment and their way of processing, by which the natural cycle operates on earth.
Current situation of environment and its reasons:
Currently, the situation of environment is so poor that could never be imagined by our old generations in previous time. We have continuously spoiled our environment by using its resources in wrong way. We can see that every day and everywhere pollution is rapidly increasing on earth whether it is air pollution, land pollution, water pollution or soil pollution. Impurity element has involved in every era of environment. Due to desire of more technical advancement, we have forgotten the importance of natural resources in our life. Number of increased factories, industries, vehicles or other transportation causes the poor situation of air pollution in whole world. The situation is so poor that IPCC (Intergovernmental panel on climate change), which is a scientific and intergovernmental body under unite nation, has declared the situation of “Global Warming” on earth due to the increased carbon dioxide in atmosphere.
Effects of polluted environment:
Pollution in air may cause various diseases among people. So many new kinds of diseases has arise due to air pollution like lung cancer or heart disease, also sometimes brain damage, problems in liver, or kidneys, etc.
Pollution in water is caused due to unlimited discharge of poisonous chemicals or other harmful elements from houses, factories, hospitals or other places into water of pond, river, lake, sea or ocean. Various diseases arise from polluted water like Typhoid, Cholera, Jaundice, Dengue, Malaria, etc.
What is solution for saving environment?
Solutions are many but all need proper action and support from all groups of people. Various organizations and firms are doing continuous efforts for saving our environment by publishing campaigns or advertisements, in which they indicate that how much this healthy environment is precious to us and how much careless we are towards our environment. Forests are the key operator of natural cycle but due to increased demand we have forgotten its importance and continuously cutting it down.
Thus, the first step to save our environment is to plant trees as more as possible by which we can get more pure air and fresh environment. Recycle is the best option for garbage or trash material discharge from houses or other places. Plastic bags or bottles should be completely banned as plastic is the major contributor to the global warming. Save or conserve water, avoid throw of dirty elements into river. Make a habit of using renewal energy like solar energy or hydro electricity to avoid consumption of coal, gases or fossil fuels. Use of private vehicles should be limited or avoided, it’s better to use public transport or CNG operated vehicles to prevent air pollution. Factories or mills should be established outside the residential area so that people could be saved from polluted air.
Conclusion:
Currently the situation of our environment is not so well and thus require quick attention from all side. Clean and green environment is the necessity of all living organisms on this earth. Fresh air, clean water and lots of trees are the basic beauty of our natural environment and no one has right to damage or destroy it.
