Resources include anything that can satisfy human needs, including natural resources like water, biotic resources, and land resources. It is important to conserve resources for current and future generations by preventing depletion and ensuring continuous long-term availability. Land resources provide agricultural land, water, and mines. Land is used for residential, commercial, industrial, and transportation purposes, but degradation through overuse of land and deforestation is a problem. Water resources are sources of water for agriculture, industry, households, and the environment, so water conservation through efficient use and management is important. Biotic resources include animals, plants, forests, and microorganisms, and various measures are taken to conserve species and their habitats.
