Natural Resources Natural resources  are useful raw materials that we get from the Earth. They occur naturally, which means that humans cannot make natural resources. Instead, we use and modify natural resources in ways that are beneficial to us. The materials used in human-made objects are natural resources. Some examples of natural resources and the ways we can use them are: Natural Resource Products or Services Air Wind energy, tires Animals Foods (milk, cheese, steak, bacon) and clothing (wool sweaters, silk shirts, leather belts) Coal Electricity Minerals Coins, wire, steel, aluminum cans, jewelry Natural gas Electricity, heating Oil Electricity, fuel for cars and airplanes, plastic Plants Wood, paper, cotton clothing, fruits, vegetables Sunlight Solar power, photosynthesis Water Hydroelectric energy, drinking, cleaning
