Key concepts and terms:Management of Natural Resources 1. Natural Resource: It is stock of the nature such as air, water, soil, minerals, coal, petroleum, forest and wildlife that are useful to mankind in many ways. 2. Pollution: It is defined as the undesirable change in physical, chemical or biological characteristics of our soil, air or water, which harmfully affect human lives or the lives of other species.
3. pH of water: pH stands for ‘potential of hydrogen’. The acidic and basic character of aqueous solutions can be described in terms of hydrogen ion and hydroxyl ion concentration. A pH below 7 indicates an acid solution and above 7 indicates an alkaline solution.
4. Three R’s to save the Environment: We can reduce pressure on the environment by applying the maxim of ‘Reduce, Recycle and Reuse’ in our lives.
5. Sustainable Development: It is the development which can be maintained for a long time without undue damage to the environment.
6. Need to manage our Resources : Our natural resources are limited. With the rapid increase in human population, due to improvement in health care, the demand for all resources is also increasing.
7. Biodiversity: It is the existence of a wide variety of species of plants, animals and microorganisms in a natural habitat within a particular environment or of genetic variation within a species.
8. Wildlife: It means all those naturally occurring animals, plants and their species which are not cultivated, domesticated and tamed.
9. Water Harvesting: It means capturing rainwater where it falls or capturing the run off in a local area and taking measures to keep the water clean by not allowing polluting activities to take place.
10. Fossil fuels: These fuels are obtained from the remains of plants and animals, which got buried beneath the earth millions of years ago, changed into coal, petroleum and natural gas due to excessive heat and high pressure inside the earth.
11. Coal: It contains chiefly carbon and its compounds mainly nitrogen, oxygen, sulphur and hydrogen. It also contains inorganic matter.
12. Non-renewable Energy Sources: These are energy sources which cannot be replaced easily when they get exhausted and are also called conventional sources of energy. Ex: Fossil fuels.
13. Uses of Fossil FuelsCoal: Thermal power plants and steam engines.Petroleum: Petroleum products like petrol and diesel are used as means of transport.
14. Management of Fossil Fuels: the natural gas is a good alternative to fossilfuels like coal and petroleum. The use of alternative source of nonconventionalenergy such as solar energy, wind energy, biomass energy, etc.should be promoted to save the reserves of fossil fuels. Biogas can also beused for various purposes.
