Earth is a habitat of human beings and other living things. Human gets all types of resources from the environment. As one of superior most creatures of the earth due to intelligence, human has a great possibility of wise use of natural resources and creating a balance in the ecosystem. Therefore, human is very closely interrelated and dependent on natural resources.
The interrelationship between human and natural resources are given below:Air and Human
Air is a significant factor which protects the life of human. Human cannot survive only for a minute without air. They takes breathe for 22,000 times per day in normal condition and gets sixteen kilogram oxygen from the atmosphere. Thus, air is a very important factor among the natural resources. If methane, nitrogen and carbon dioxide are mixed in air, it causes air pollution. It makes human ill. The fresh air protects the life of human. Thus, there is close relationship between man and air.
Water is another significant resource for the survival of living beings. Human uses water for drinking cleaning, cooking food and irrigation of agricultural land. In absence of water, plants cannot grow and human are deprived of food from plants. It also acts as an important metabolite of our body and forms seventy percent of our body mass. Therefore it is very much essential to conserve water resources by controlling the possible causes of pollution.
Land is that part of the earth over which we live. Plants and vegetation develop on land. Natural resources like minerals are found in land. Land is formed of solid, rock and liquid materials in the shape of a ball. It occupies 13 part of the total land of the earth and it is also called lithosphere. Soil is formed out of the broken grains of rock which is caused by physical, chemical and biological process. Thus, land is such a control point which keeps us safe, provides food, shelter, and gives fresh water to drink. It provides and maintains the balance in the nature. Therefore, there is a close relationship between human beings and land.
Human depends on plants and other animals for his nutrient supply. Plants have capacity to convert radiant energy of the sun into chemical energy by photosynthesis, so a nutritional chain is established in the nature from plants to animals and then to human beings. Human uses various forest resources like timber, medicinal herbs, plants, animal's materials for his livelihood. Human collects fodders and firewood from the forests. A plant also plays a significant role to maintain a balance in the amount gases of the air.
The things available free under the earth are called minerals. Copper, tin, lead, magnetite, limestone, natural gas, marble are some minerals. Mankind should be able to make the best use them wisely to increase the national wealth. Minerals help in accelerating the economic development of the country. Truck, jeep, car, motorcycle, train, airplanes, car, motor, etc are run by the petroleum which is found under the ground as mineral.
Animals are important natural resources. Many domestic animals act as sources of food for human. Wildlife provides beauty in the nature and promotes tourism which directly benefits man by providing employment opportunities. On the other hand, survival of animals depends on human activities. Activities like forest fire, poaching, deforestation depletes the wildlife and their species may reach at the verge of extinction.
