NATURAL RESOURCES
2
Purpose of the chose this topic
Natural Resources are all that exists without the actions of humankind. This includes all natural characteristics such as magnetic, gravitational, and electrical properties and forces. On earth we include sunlight, atmosphere, water, landl (includes all minerals) along with all vegetation and animal life that naturally subsists upon or within the heretofore identified characteristics and substances. Particular areas such as "The rainforest in ”Fatu –Hiva " are often characterized by the biodiversity and geodiversity existent in their ecosystems. Natural resources may be further classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, and air , as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores , mineral oil , and most forms of energy.

Renewable resources Renewable resources are those that are present in unlimited quantity in nature or those that will replace themselves over time. These resources are not likely to be exhausted by human activities. As they are unlimited, they are also called inexhaustible resources. Example: Air, water

Non-renewable resources
Non-renewable resources are those that are limited in nature and will not replace themselves. They can be exhausted by human activities. As they are limited, they are also called exhaustible resources. Example: Coal, petroleum and natural gas are exhaustible fossil fuels, They cannot be prepared in the laboratory. It takes millions of years for dead organisms to get converted into these fuels.

Effects of using fuels Burning of these fuels is also a major cause for air pollution and along with cutting down of trees, is contributing to global warming

Conservation of Natural resources
Natural resources need to be conserved and this can be done by conserving energy. The Petroleum Conservation Research Association (PCRA) of India has some tips for people on how to save petrol/ diesel while driving: • Drive vehicles at a constant and moderate speed. • While waiting or at a traffic junction, switch off the engine. • Ensure correct tyre pressure. • Ensure regular maintenance checks of the vehicle.
