__//**Economic Land Use Model**//__

According to a report by the United Nations’ Food and Agriculture Organization, land degradation has been increasing where there has been an absence of any land use planning. As a consequence, the result has been misery for large segments of the local population and the destruction of valuable ecosystems. Such approaches should be replaced by a technique of frequent land use. This will ensure the long-term quality of land for human use.
 * Definition -** The economic land use model explains that people should develop the necessary resources for use today.
 * Explanation -** The economic land use model being undertaken by economists involves human decisions and how they affect the pattern of land use. This theory, or idea is supported by many.
 * Example -** An example of this model would be the world’s current fossil fuel production. However, fossil fuels are nonrenewable because they take millions of years to form. In addition, fossil fuels are greatly affecting the environment. In the U.S. 90% of greenhouse gas emissions comes from the combustion of fossil fuels. Nonetheless, they continue to be used for energy around the world.



__//**Sustainability Land Use Model**//__


 * Definition -** The sustainability land use model proposes that people should develop resources as long as they can be replaced.
 * Explanation -** This can be achieved by converting nonrenewable resources to renewable resources. Some renewable resources that exist today are wind, hydroelectric, water, and solar power. However, most renewable resources have been proven not efficient enough compared to nonrenewable resources, such as petroleum. In addition, some resources can be recycled. These common materials include cardboard, glass, plastic bottles, and paper.
 * Example -** An example that supports this concept is the phrase "reuse and recycle". This phrase tries to encourage humans to recycle their unwanted trash. However, this trash is not dirty plates or candy rappers. These recyclables include plastic, cardboard, and paper. In addition, the use of solar and wind energy supports the model as well.




 * __//Environmental Land Use Model//__

Definition -** The environmental land use model states that human development should impact the environment as a little as possible.
 * Explanation -** With development, comes the possibility of pollution. This model proposes that as we develop, we should not pollute the environment along the way. The major effect of land use on land cover since 1970 has been deforestation of temperate regions. More recent effects of human development include urban sprawl, soil erosion, soil degradation, and desertification.
 * Example -** An example that supports this model is the National Park System. The organization takes full care of national and local parks. They make sure nothing is disturbed within the park by human development.




 * __//Preservationist Land Use Model//__

Definition -** The preservationist land use model states that humans should not develop certain regions.
 * Explanation -** Supporters of the model aim to meet several goals: the preservation of several animal species homes, legal constructions that should make land protections permanent, and the teaching of why rural lands are important to our environment. Another controversy that deals with this model is the destruction of several tropical rainforests. As people destroy rainforests for the construction of farms or towns, animals' homes are destroyed.
 * Example -** A classic example of supporters is the Wild Life Refuge. This organization hopes to stop the invasion of humans into an endangered species homeland. The Wild Life Refuge places some of these endangered species into a safe facility where they are cared for daily.
