Natural resources are anything supplied by Mother Nature that can be used by living beings. They exist on the planet without human activity for their creation. Examples include water, forests, fossil fuels, minerals, plants, animals, and air.
Natural resources are classified into two types: renewable and non-renewable. Renewable resources have an unlimited supply and can be used repeatedly, such as air, sunlight, and often water. However, water can become non-renewable if chemically polluted, and only a small fraction of Earth's water is fresh and accessible. Air pollution also needs to be reduced to maintain its renewability.
Non-renewable resources are available in limited quantities, do not regenerate, or take a very long time to return. Overuse can lead to their extinction. With the increasing human population, we are consuming more non-renewable resources like plants, animals, soil, and fossil fuels (coal, petroleum, natural gas) at an alarming rate, risking their exhaustion. These are also called exhaustible natural resources.
Natural resources are vital for human survival. Without careful monitoring and conservation, future generations will face shortages of food, housing materials, and energy. Therefore, understanding the difference between exhaustible and inexhaustible resources and practicing sustainable development is crucial. Sustainable development means meeting present needs without compromising the ability of future generations to meet their own needs.
There is a significant disparity in resource consumption globally. People in rich countries consume up to 10 times more natural resources than those in poorer countries. For example, North Americans consume approximately 90 kilograms of resources daily, while Africans consume around 10 kilograms per day.
