Natural resources

  1. 1. Natural Resources ● Natural Resource: is any useful material found in the environment. – Soil – Water – Minerals – Vegetation ● Anything that helps meet people's needs..
  2. 2. Different types of resources 1. Recyclable Resource: Resources that cycle naturally throughout the environment. (water cycle) 2. Renewable Resources: A resource that can be replaced in a timely manner. (corn, livestock) 3. Nonrenewable Resources When they are used up, they cannot be replaced in a timely manner. (minerals, coal, natural gas, petroleum/oil)
  3. 3. Fossil Fuels ● Fossil Fuels were created over millions of years from the remains of prehistoric plants and animals. ● These fuels are no longer being created. (nonrenewable) ● Examples: coal, natural gas, petroleum.
  4. 4. How people use the Land.. ● People across the world use their land and natural resources in different ways. ● We categorize these different ways into three stages. – First-Level Activities – Second-Level Activities – Third Level Activities
  5. 5. First-Level Activities ● At this level people use land and resources directly to make products. – Hunt, cut wood, mine, fish ● As the world develops fewer and fewer people are at this level.
  6. 6. Second-Level Activities ● At this level people turn raw materials into things they use. – Farmer takes his corn crop to a mill and have it turned in to corn meal. ● Raw materials are manufactured into a finished product. Corn Mill
  7. 7. Third-Level Activities ● At the third level, goods are no longer being made, but rather a service is being provided. ● More industrial nations require service industries. ● Service industry— providing a service rather than producing a good or service.
  8. 8. Developing vs. Developed Nations ● Developed Nations – Lots of Industry – ¼ of the world – Use goods made in factories. – Consume a great deal of raw materials. – Most live in towns/cities. – Most have food & water – Good healthcare & Education – Commercial Farming Problems: Unemployment, environmental problems, shortage of natural resources ● Developing Nations – Little Industry – Majority of the word's population. – Subsistence Farming – Live off the land. – Little wealth – Many hunters-gathers. Problems: disease, food shortages, unsafe water, poor education and health services, and changing governments.
