For centuries man has considered the earth and environment as unlimited resources but many changes have affected our environment in many ways.
In this article we will tell you about our environment, what is the importance of environment and how to use it to keep it healthy for the coming generations?
what are the environment
Environment words french words Environ which means surrounded or surrounding and ment means action. Overall environment or environment is the interaction between the organism and the nature.
The world that surrounds an organism and which it is affected by is called its environment or environment. Since the origin of man, man has had a relationship with the environment. This relationship from his birth to the present can be divided into four parts.
1. Phase I – In this phase human had co-existence with nature, meaning in this phase, nature itself dominated human beings, due to which the environment remained very pure.
2. Phase II – Nature was conquered to some extent by humans in this phase. Still, the environment remained pure when it was not completely dominated.
3. Phase III – In this phase man completely conquered nature and took his steps towards development. Humans got control over nature and started using and exploiting natural resources. Due to which some pollution was generated in the environment but it was not harmful to human health.
4. Fourth Stage – In this phase man took complete control over nature. In this, man made great use of natural resources according to his convenience and destroyed the condition of nature itself. Due to which the amount of pollution has increased so much that the matter of protection of the environment has started rising.
There are many types of environment for human beings like home environment, business environment, political environment etc. But we will talk only about the natural environment like air, water, land, trees, plants and other organisms.
There are mainly two components of environment –
1. Biological components – Biological component is called that part of the environment in which living animals or plants are found. This in turn takes care of the maintenance of the environment. For example trees, plants, humans and animals etc.
2. Abiotic components – Abiotic components are those components of the environment in which non-living things and things are found. For example light, rain, water, temperature, atmospheric gases, weather changes etc.
type of environment
There are mainly three types of environment –
1. Natural Environment
The environment which comes from nature is called natural environment. For example, the natural environment of the pond in which the fish lives is that pond.
Other organisms living in the pond such as insects, frogs and other creatures can be food for that fish. In this way that fish will get all the facilities to live in that pond then it will be its environment.
2. Man-made Environment
Environments that have been created by humans such as farms, cities, villages, towns, dams, etc. For example, we humans live in houses built by us. which is our environment. But this environment is not natural because it is created by humans only.
The environment created by humans uses large amounts of matter and energy and requires maintenance, monitoring and management.
3. Human Modified Environment
The environment which man creates by modifying the natural environment is called human modified environment. For example, we do not drink river water directly, but first purify it to drink it.
In this way, the water of the river is natural but changes have been made in it by humans, due to which it comes under human modified environment. Apart from this, gardens, sanctuaries, etc. are also types of man-modified environment.
field of environment
There are mainly four areas of environment –
The outer layer of the earth on which continents, oceans, trees, plants, etc. are found is called the lithosphere. 29% of the earth’s surface is covered by land and 71% is water.
There is an expansion of the hydrosphere on about part of the earth, in which oceans, oceans, oceans, etc. are found. 97.5% of the total amount of water present on Earth is in the oceans which is saline. Only 2.5% of the remaining water is fresh water.
The gaseous envelope that surrounds the Earth up to a height of thousands of kilometers is called the atmosphere. 97% of the atmosphere is confined to an altitude of 29 km. Many types of gases like nitrogen, oxygen, carbon dioxide, etc. are found in the atmosphere.
The area of the earth where water, land and air together make life possible is called biosphere. The biosphere occurs almost everywhere on the earth, such as humans on land, animals and fish in water, frogs and birds in air, etc.
Environment has the following functions.
1. Provides supply of resources.
Environment provides resources for production. It includes both renewable and non-renewable resources.
Example: Wood for furniture, soil, ground, etc.
2. Maintains life.
The environment includes the sun, soil, water and air, which are essential for human life. It sustains life by providing genetic and biodiversity.
3. Eliminates waste.
Waste is generated by producing and consuming the resource. It is mostly in the form of waste. Helps get rid of environmental waste.
4. Enhances the quality of life.
Environment enhances the quality of life. Man enjoys the beauty of nature which includes rivers, mountains, deserts etc. These improve the quality of life.
What is an ecosystem or ecosystem?
The organisms of the biosphere are closely related to each other with the environment. They are connected to each other, due to which the atmosphere is balanced. The reduction or extinction of any one has a bad effect on the environment.
The various components of the biosphere and the exchange of energy and matter between them all together form an ecosystem.
In other words, we can say that living things, non-living things, natural resources and man-made resources etc. together form a favorable environment in which life is possible, it is called ecosystem or ecosystem.
importance of environment for life
Whatever type of organisms are they need a good environment for life. We use the land to grow crops.
Soil provides essential nutrients for plant growth. If the soil lacks nutrients, then fertilizers need to be added to them.
Climate and weather changes are mainly identified by temperature, pressure and rainfall. The air of the atmosphere provides oxygen to the living beings, without which the life of the living can be in danger.
In this way the environment is very important for us, every natural thing present in the environment is responsible for our life. If none of these things are there then our life will become very difficult or impossible.
environmental laws in india
India is not behind any country in making environmental laws, so far about 200 laws have been made in this regard in India.
Environment Protection Act, 1982
The main objective of this act is to protect and improve the environment. It applies to the whole country. The following rights have been included in this Act.
- To plan and implement to prevent pollution of the environment.
- Determining the level of environmental quality.
- Regulating areas in which industries cannot be established.
- To prepare programs for taking precautions against accidents that pollute the environment.
- To investigate all substances and processes causing pollution.
