people are dependent on exhaustible resources such as coal petroleum etc. we should not use exhaustible resources because they take millions of years to reform and they are limmited also. Many of them are fossil fuels. we should inexhaustible resources because they can be used again and again.
People depend upon exhaustible resources because they are used in various purposes like running the vehicles and in aeroplanes etc.....

Natural resources refer to all materials in nature that are required by humans for their well-beings. In other words, humans are totally dependent on natural resources for survival. For instance, they grow crops, catch fish, and rear livestock and poultry for food; they exploit fossil fuels for energy supply; they cut down timber, extract minerals, and collect water for various uses in industry, construction, and many aspects in daily life. Natural resources are customarily classified into renewable resources and non-renewable resources.
Renewable resources are resources that can be regenerated fairly rapidly through natural processes. Examples include oxygen, minerals in soil, wildlife, timber, fish, and fresh water. Theoretically, these resources are renewed naturally and are always available. However, if the rates of use exceed the rates of renewal, the resources will become depleted. Three of the renewable resources: timber, fish and fresh water, will be discussed below.
Timber is a very useful raw material in our daily lives. We obtain timber by removing forests in various parts of the world. Forests cover about 25% of the land surfaces on the earth. They have a special role in the conservation of biodiversity and provide homes for more than half of the world’s plant and animal species.
Water covers about 70%of the surface of the earth. This huge biological system comprises very diverse habitats and very great biodiversity. The oceans are very important for human existence. It is a regulator of atmospheric composition and a site for nutrient cycling. The oceans, of course, are important in supplying humans with food; the most important ones are fish.
Oceans, lakes, rivers, glaciers, and other sources of water cover about 70% of the earth’s surface. Although water is abundant on the earth, most of it is unavailable for human use due to salinity or unreliability. Only less than 3% of water on earth is fresh water, and about three-quarters of which is tied up in glaciers, ice caps, and snowfields. Nevertheless, ground water is another important sources of fresh water. It is held underground in porous, water-bearing layers of sand, gravel and rocks.
