Natural resources are those things that formed from the biotic and abioytic factors in the atmosphere, and which are used by man for various purposes. Natural resources are of two types’ renewable resources and non-renewable resources.
They can make again and again according to the use.
E.g.: timber, paper, trees, fire woods, food crops etc…..
They can’t be made once they are used up.
E.g.: metals, kerosene, petrol, natural gas, coal, diesel, minerals etc…..
Cause of depletion of natural resources
Man is exploiting the natural resources excessively as part of his existence. The main causes of depletion of natural resources are:
-natural calamities like flood and drought
As population increases the depletion of natural resource will also increase. It is because of the necessary activities of man. Man over exploit natural resources for his comforts. This can ultimately lead to the scarcity of these resources in the near future. This can ultimately threaten the existence of life on the earth.
Due to the deforestation cause the decrease of rainfall and amount of firewood. Due to this, 200 cores of people suffer from the scarecity of water. Besides this, man over consuming the available source of water. This activity will definitely affect future generations.
Today the number of motor vehicles is increasing day by day. This needs a huge amount of petroleum and diesel. One liter of petrol will burned out when a motor car runs about 10 km of distance. How many such vehicles! The fossil fuels have been formed in the earth by steady process of cores and cores of years. Many years required to formulate 1kg of fossil fuels.
If this types of over consumption of fossil fuels continuous, the fossil and fuels will disappear from the world.
Only human constitute the steadily increasing resources. When human population increases, the use of natural resources also increases. Man over exploits natural resource for his comfort. This may lead to scarcity of these resources in the near future. This can ultimately threaten the existence of life on earth.
Man is a virus that destroys the resources, as cancer destroys the humans. Humans destroy the natural resource of the entire world.
Conservation of natural resources
Indiscriminate use of natural resources will be a threat even to the existence of man. But it doesn’t mean that we should not use natural resources. We cannot live without these natural resources. So we must use them patiently and have to conserve it.
The methods for keeping the quantity of natural resources steady without any loss are:
- Take the responsibility to conserve natural resource.
- Reduce the consumption of natural resources.
- Renew in the same time the resource that can be renewed.
- Use non-conventional energy instead of conventional.
- Strictly control consumption of resources that are non-renewable.
- Develop more energy resources.
- Use smokeless fuel efficient motors.
If we could follow these, it’s a good thing for our future generation.
