Introduction Natural Resources:
Natural resources are the raw materials supplied by the earth and its processes and include things in the physical environment used for housing, clothing, heating, cooling, transportation and to meet other human wants and needs. Common uses of natural resources are everywhere.
Importance Of Natural Resources:
It is nearly impossible to cease consuming natural or geologic resources altogether. Trees are used for shelter, animals for food and clothing, plants for medicine, minerals and fossil fuels for power, transportation, heating and cooling. These resources include soil, air, water, sunshine, forests, wildlife, fish, fossil fuels, metals and minerals produced by the earth’s natural processes. Using natural resources to meet human needs and wants has an impact on the global environment. Each time raw materials are used to produce goods, there are ecological, social, and economic impacts. Managing these natural resources and utilizing conservation techniques is necessary to help societies meet present and future needs. The primary economic value of a matured resource derives from the services it provides humans.
Type Of Natural:
Natural resources that can be replaced and reused by nature are termed renewable. Natural resources that cannot be replaced are termed nonrenewable.
Renewable resources are replaced through natural processes at a rate that is equal to or greater than the rate at which they are used, and depletion is usually not a worry. Some common examples include: § Air (wind)
- Fresh water
- Living organisms (trees)
Soil is a natural resource, which is required for production of food, industrial raw materials as well as for generation of energy resources. It is also a natural value, which is protected as natural heritage.
Non Renewable Resources:
Nonrenewable resources are exhaustible and are extracted faster than the rate at which they formed. Some common examples are:
Fossil fuels (coal, oil, natural gas)
- Diamonds and other precious gems and minerals
- Types of metals and ores
Nonrenewable resources such as these exist in a fixed amount and can only be replaced by processes that take millions of years. If they are depleted, they are depleted for good. Sometimes, however, renewable resources can be depleted if they are used too fast.
Because of the severe impact that we impose on the land, air, and water, conservation has become increasingly important.
