The list presented below, classifies natural resources in a manner that helps us to become aware of the fast-depleting natural resources. While studying the subject of natural resources, kids should understand that their conservation is the a need of time. Educating them about how to make judicious use of natural resources is important. The information about renewable natural resources through examples of wind and tidal energy provided at the end should also prove to be useful.
- Water: It is the most important natural resource and one cannot survive without water. We can see that life thrives/flourishes in the presence of water. It is a natural resource needed by all living beings not only for survival, but also to grow and develop.
- Air: The most abundant and important natural resource for survival, air (in the form of oxygen) is needed by most creatures (except for anaerobic organisms) found on earth.
- Sunlight: Just like air and water, sunlight is needed for survival of living beings. The process of photosynthesis is carried out in the presence of sunlight. With plants visibly circulating most of the energy in the food chain, one tends to forget that sunlight is the original source of energy for life on earth. The water cycle too cannot be completed without sunlight.
- Plants: The plants are the main energy source for living beings on earth. Carnivores and scavengers obtain energy by feeding on other animals which in turn, feed on plants. Though plants are considered a renewable natural resource, their excessive use could deplete them. For example, the Amazon forest cover is fast shrinking which is a dangerous sign for the health of our ecosystem.
- Wind Energy: It is one of the least used natural resources on earth. The process of obtaining energy from wind doesn't pollute the environment. Air pollution resulting from combustion of fossil fuels can be reduced to a great extent with the use of wind energy.
- Tidal Energy: This form of energy is similar to wind energy in terms of functioning. In fact, the tides/waves of oceans used to obtain energy, originally obtain it from wind. More information in the form of facts about tidal energy should be useful.
- Soil: It is one of the most abundant resources found on earth. Soil is needed for growing crops. The same soil can be used over and over for the purpose of agriculture. However, this natural resource needs to be protected from the menace of erosion. Increasing the vegetation i.e. forest cover is the best way to prevent soil erosion.
- Currently Used Resources: These are the natural resources currently used for human consumption. Coal, petroleum, etc. are some of the examples of these natural resources.
- Potential Resources: These are the untapped resources of nature. The potential resources can be put to future use. Hydrogen is one such resource which has the potential to be used as fuel in the future.
