3. These are things that occur and can be found in nature. These are things used by people to survive or to satisfy needs.

4. Kinds of Resources Renewable Nonrenewable These are unlimited resources. These are resources that can be replaced easily and can be replenished in a short period of time. These are limited resources. These are resources that cannot be replaced easily because it cannot be replenished in a short period of time.

7. ENERGY RESOURCES

8. Solar Energy Energy from the sun is converted into electrical energy using solar panels. It is the cleanest and most abundant renewable energy source available. Solar energy has two advantages: the “fuel” is free, and it’s nonpolluting.

9. Geothermal Energy It is contained in the rocks and fluids beneath the earth's crust and can be found as far down to the earth's hot molten rock called magma. It is carried by water and steam to the earth’s surface to generate electricity.

10. Geothermal Energy Hot water is used directly for heating and to turn turbines to generate electric power. Geothermal energy is harnessed by tapping natural underground reservoirs of steam and hot water. Geothermal power is nonpolluting but reservoirs are easily depleted.

11. Hydropower or Hydroelectric It is derived from falling or fast-running water which may be harnessed for useful purposes. It is the conversion of energy from flowing water into electrical energy. The water held in a reservoir behind a dam is a form of stored energy that can be released through the dam to produce electric power.

12. Hydropower or Hydroelectric Hydroelectric power, which is generated by falling water, drives turbines that produce electricity. Limited usable sites and the finite lifetime of hydroelectric dams are both obstacles to further expansion.

13. Tidal Power Tidal power is harnessed by constructing a dam across the mouth of a bay or an estuary in coastal areas with a large tidal range. The strong in- and- out flow that results drives turbines and electric generators.

14. Coal It is black or brownish-black, solid rock that can be burned and used as fuel to generate electric power. It is taken under the ground through mining. It is one of the causes of air pollution when used as fuel which produces carbon dioxide, a greenhouse gas.

15. Natural Gas It is used as fuel to produce electricity. It produces the least carbon dioxide among fossil fuels.

16. Wind Energy or Wind Power Winds are used to generate electricity. Wind turbines convert the kinetic energy of the wind into electrical energy.

17. Wind Energy or Wind Power Wind energy is a promising source of energy, but technological advances are needed to fully realize its potential.

18. Nuclear Energy In nuclear fission, the nuclei of heavy atoms such as uranium-235 are bombarded with neutrons. The uranium nuclei then split into smaller nuclei and emit neutrons and heat energy. About 7% of U.S. energy needs are met by nuclear power. Although it was once believed that nuclear power would be a safe and clean energy source, cost and safety are obstacles to expanded nuclear power. Fears about radioactive materials were realized in 1986, when a reactor at Chernobyl caused two explosions.

19. Nuclear Energy

20. Natural resources are all connected in a way. We tap into their supply to survive and also to function properly. Therefore, if one is taken away, it has a great effect on other resources. When water is eliminated from an area, the vegetation, soil, animals and even the air in that area will be affected negatively.

43. 7. poaching, smuggling of endangered organisms and illegal hunting

44. All resources used by humans are not in endless supply. Lack of environmental awareness, human greed, and carelessness are threatening the natural resources to their depletion and extinction.

45. To conserve natural resources is to protect or use them wisely without wasting them or using them up completely. Sustainability of natural resources means conserving them to make them last. Therefore, each of us should take part to make these resources available for future generations.

46.   Ways of Conservation of Natural Resources: Policies, laws and ordinance that will emphasize protection and conservation of Natural Resources Seminars, lectures and campaigns that will develop further environmental awareness.

47.   Ways of Conservation of Natural Resources: Tree planting projects Energy conservation by participating the EARTH HOUR Promote use of bicycle and walking instead of vehicles to conserve fuel and to avoid pollution.

48. Why Conserve Energy? Energy conservation plays a very important role because utilization of non- renewable resources also impacts our environment. Specially, usage of fossil fuels supplies to air and water pollutants such as carbon dioxide. Fossil fuels were formed from plants and animals that lived millions of years ago and are buried deep in the earth. Examples are coal, petroleum (crude oil), and natural gas.

49. Why Conserve Energy? Carbon dioxide (CO2) which is naturally present in the air in small amounts is produced by burning fossil fuels like the natural gas and petroleum. Studies show that an increase in carbon dioxide in the atmosphere increases atmospheric temperature resulting in global warming.

51. Protecting Resources 1. Starting in the 1970s, the federal government passed several laws to prevent or decrease pollution and protect resources. • Although they comprise only 6% of the world’s population, Americans use about one third of the world’s resources. • Conservation is the careful use of resources.

52. Protecting Resources 2. In 1970, Congress passed the Clean Air Act, the nation’s most important air pollution law. • The Clean Air Act limited the amount of pollutants allowed in the air, resulting in improved air quality.

53. Protecting Resources 3. Protecting land resources involves preventing pollution and managing land resources wisely. Farmers are using new soil conservation practices to prevent the loss of topsoil. Some farmers and gardeners use fewer pesticides and inorganic fertilizers. Compost is partly decomposed organic material that is used as fertilizer.

54. Protecting Resources 3. Protecting land resources involves preventing pollution and managing land resources wisely. Better landfill management and disposal techniques prevent waste seepage. Recycling is the collecting and processing of used items so they can be made into new products.
