    There are various methods of categorizing natural resources, these include source of origin, stage of development, and by their renewability. On the basis of origin, natural resources may be divided into two types: Biotic — Biotic resources are obtained from the biosphere living and organic material , such as forests and animals , and the materials that can be obtained from them. Fossil fuels such as coal and petroleum are also included in this category because they are formed from decayed organic matter. Abiotic — Abiotic resources are those that come from non-living, non-organic material. Examples of abiotic resources include land , fresh water , air , rare earth metals and heavy metals including ores , such as, gold , iron , copper , silver , etc. Considering their stage of development, natural resources may be referred to in the following ways: Potential resources — Potential resources are those that may be used in the future—for example, petroleum in sedimentary rocks that, until drilled out and put to use remains a potential resource Actual resources — Those resources that have been surveyed, quantified and qualified and, are currently used—development, such as wood processing , depends on technology and cost Reserve resources — The part of an actual resource that can be developed profitably in the future Stock resources — Those that have been surveyed, but cannot be used due to lack of technology—for example, hydrogen Many natural resources can be categorized as either renewable or non-renewable: Renewable resources — Renewable resources can be replenished naturally. Some of these resources, like sunlight, air, wind, water, etc. Though many renewable resources do not have such a rapid recovery rate, these resources are susceptible to depletion by over-use.

    A resource is considered to be non-renewable when their rate of consumption exceeds the rate of recovery. Examples of non-renewable natural resources are minerals and fossil fuels. There is constant worldwide debate regarding the allocation of natural resources.

    The discussions are centered around the issues of increased scarcity resource depletion and the exportation of natural resources as a basis for many economies especially developed nations. The vast majority of natural resources are exhaustible which means they are available in a limited quantity and can be used up if they are not managed correctly.

    Natural resource economics aims to study resources in order to prevent depletion. An example of natural resource protection is the Clean Air Act. The act was designed in to control air pollution on a national level. Regulations were established to protect the public from airborne contaminants that are hazardous to human health. The act has been revised over the years to continue to protect the quality of the air and health of the public in the United States. Wind: Wind is an example of a renewable natural resource.

    It occurs naturally in the environment and has the ability to replenish itself.

    It has also been used as a form of energy development through wind turbines. Learning Objectives Explain basic natural resource economics Key Takeaways Key Points As a field of academic research, natural resource economics addresses the connections and interdependence between human economies and natural ecosystems. By studying natural resources, economists learn how to develop more sustainable methods of managing resources to ensure that they are maintained for future generations.

    Natural resource economics is studied on an academic level, and the findings are used to shape and direct policy-making for environmental issues. These issues include resource extraction, depletion, protection, and management. Natural resource economics findings impact policies for environmental work including issues such as extraction, depletion, protection, and management.

    They move round and round in cycles and never run out. When an animal like this cow eats a plant, it takes in nutrients. The nutrients are used in the animal's body and then many come out as waste, which returns the nutrients to the soil. When the animal dies, nutrients will return to the soil as well. Plants take up the nutrients in the soil and continue the cycle.

    Nonrenewable natural resources Now, let's look at nonrenewable natural resources. They are found in the ground. There are fixed amounts of these resources. They are not living things, and they are sometimes hard to find.

    They don't regrow and they are not replaced or renewed. They include the fossil fuels we burn for energy natural gas, coal, and oil. Minerals, used for making metals, are also nonrenewable natural resources.

    Nonrenewable natural resources are things that take longer than a person's lifespan to be replaced.

    In fact, they can take millions of years to form. Fossil fuels such as oil, coal, and gas will not last forever. They are nonrenewable. People are trying hard to find new fuels that are clean and will provide the power we need.

    Natural resource - Wikipedia

    Wind, solar, and hydrogen power are renewable resources that offer hope for the future. People use both types of natural resources to produce the things they need or want. Our homes, clothing, plastics, and foods are all made from natural resources.

    Let's look at each one of these to be sure. Your home is in a building. Buildings are made out of wood and minerals. Wood is from trees. Minerals are mined from the ground. Bricks, cement, and metals are made from minerals. How about your clothes? Most of your clothing is made from cotton, polyester, or nylon. Cotton comes from cotton plants. Polyester and nylon are made from oil. Plastics are made from oil too.

    How about your food? People eat grains, fruits, and other parts of plants. You may also enjoy dairy products and meat from animals.
