The Earth may be divided into recognizable and distinguishable environments called ecosystems. As these populations grow, so grows the need for resources. Humans use and consume natural resources. All energy for our planet has its source from the Sun. Humans obtain their energy from natural resources.
Humans use natural resources for energy to provide food, transportation, and even shelter.
In a modern society fuel is needed to farm and deliver food to stores. Automobiles are needed to transport people and products. Power machinery is needed to build homes. The availability and quality of a community s water and air greatly influences the quality of life in that community. A community lacking water, for example, must import water in order for the community to survive.
