Homo sapiens first appeared on earth nearly 200 thousand years ago. And since, then, we have depended on Mother Nature for things needed by us to survive. Humans require air, water, food from plants and animals, sunlight, minerals, land, soil and fossil fuels to exist. All these useful raw materials are called natural resources.
The picture below gives us a few examples of the numerous things we obtain from natural resources.
Different Types of Natural Resources:
There are many ways of classifying these natural resources. They can be biotic or abiotic(that is derived from organic materials or inorganic materials). Another way of classification of resources is by the amount of resource available for human consumption. Through this, resources can be classified into exhaustible and inexhaustible natural resources.
1. Inexhaustible Natural Resources:
Nature has blessed us with an unlimited supply of resources such as air, water and sunlight. These resources are called inexhaustible resources. They are also called renewable resources.
2. Exhaustible Natural Resources:
As the human population is increasing at an astounding rate, we have reached a number of 7.4 billion today! Naturally, this means that we are utilizing more and more natural resources. If we go at this rate, we will soon reach a day when nature will not be able to provide us with resources such as plants and trees, animals, mineral ores, fossil fuels such as coal, petroleum and natural gas. Thus, these resources are exhaustible. These resources are called exhaustible or non-renewable resources.
If the use of these resources is not monitored carefully, there will be no food for our predecessors to eat, no energy for them to power their machines and no material for them to build a shelter with. This is why it is important to understand which resources are exhaustible and which are not, and to practice sustainable development. This is nothing but the development that meets the needs of the present generations without compromising the ability of future generations to meet their own needs.

1. Why are natural resources important?
Ans: Resources are important to any country’s development. For example, to generate energy, fossil fuels are needed; and mineral resources are needed for industrial development.
2. How do humans depend on natural resources?
Ans: Living things require food, air, and land services, so they live in places with the things they want. For all they do, humans use natural resources. Human use of energy and fuels is derived from natural sources and its use affects the environment.
3. Is soil a natural resource?
Ans: Soil consists of air, water, minerals, and organic material and is one of the world’s most important natural resources. Most life on earth as a direct or indirect source of food depends on soil. Plants and animals are the source of their nutrients from the soil and are home to many different life forms.
4. What makes natural resources valuable?
Ans: Natural resources are Earth materials used to support life and meet the needs of people. Any organic material used by humans can be considered as a natural resource. Natural resources include oil, coal, natural gas, metals, stone, and sand. Air, sunlight, soil, and water are other natural resources.
5. Why is freshwater an important natural resource?
Ans: Freshwater is vital for life. For live, crops, animals, and humans all need fresh water. When part of sewage systems, and in industrial plants, to name a few, they use drinking water to irrigate crops. Rain and snowfall replenish water from soil, rivers, and lakes.
