Introduction to Natural Resources
The resources that are available in nature are called natural resources. These resources are important components of our life. Natural resources include air, water, soil, minerals, forest, wildlife, microbes, climate, etc. They are invaluable gifts of nature. In other words, all the things that exist in nature and can not be created by human effort are called natural resources. All the living beings including humans are dependent on natural resources for the fulfillment of their basic requirements and survival. In the same way, we get various kinds of foodstuffs like rice, maize, millet, vegetables, fruits, kinds of seafood, fresh air, water, and other various life-supporting natural resources for our survival, reproduction, growth, development and life cycles.
Classification of Natural resources
Natural resources are classified as perpetual, renewable, non-renewable, which are as follows:
1. Perpetual Natural Resources
The resources which never deplete despite their continuous use are called perpetual resources. They are also called unlimited resources. The best examples of perpetual resources are solar energy, wind, tides, flowing water, etc. the perpetual natural resources can be transferred into energy. to produce electricity with the help of following water and sunlight is an example of it.
2. Renewable Natural resources
the resources which can be regenerated and maybe self renewed at a certain duration of time are called renewable resources. animals, plants, fresh air, fertile soil are the best examples of renewable resources. The resources like plants and animals can naturally reproduce themselves. similarly, fresh air, fertile soil, freshwater can be obtained through their regeneration process. like non-renewable resources the renewable resources also may be exhausted or depleted if they are overexploited. Hence, people should realize that the rational use of renewable natural resources allow them for the regeneration and restoration process.
3. Non-renewable Natural resources
the resources that cannot be regenerated once they are exhausted or finished are called non-renewable natural resources. they are in fixed deposit in the Earth. Fossil fuel, natural gas, metallic minerals, and nonmetallic minerals are examples of nonrenewable natural resources. They are in limited quantity on the Earth. After their continuous use, their deposits may be empty. Once they gey finished, it is impossible to get them again. We have to seek alternative resources to conserve these precious natural resources.
Importance of Natural Resources
All forms of natural resources like air, water, plants, animals, forest, minerals have their own importance. Some of the importance is given below.
– Source of Fresh Air and Water
-Source of Foodstuffs
