Water is a renewable resource in the sense that it replenishes itself through rain. However, it is possible to use water in ways that render it a non-renewable resource.
A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.
There are increasing concerns about water scarcity in many parts of the world, particularly in developing nations or regions of high population density. Only 3 percent of the Earth's water is fresh water, and only one-third of that amount is usable for drinking water. The rest of Earth's fresh water is part of ice caps and glaciers. In many of the world's most populous regions, potable water is a scare commodity because of overuse, mismanagement and pollution.
Hydroelectric power is one important use of water as a renewable resource. Water power is efficient, produces very little waste comparative to other energy sources and the water is reusable.Learn More
Coal is formed in a swampy depositional environment that includes the remains of trees and shrubs. This swampy environment is able to bury plant life quickly before it rots. Once buried, the plant life is heated and compressed to form coal.Full Answer >

Deforestation can generate income for farmers, land developers and national economies, but deforestation can have a negative impact on local and global ecologies and ecosystems. The population in most countries is increasing, which puts pressure on local economies to produce more food or clear more land for urban development priorities such as housing and commerce. Cutting down forests not only generates income from the sale of timber, but also clears land for use in development. On the other hand, forests are vital parts of local and global ecosystems. Cutting down forests, especially jungles and rain forests, often threatens species of wildlife and ultimately contributes to dangerous trends such as global warming.Full Answer >
Exhaustible resources, or nonrenewable resources, include fossil fuels, mineral ores and uranium. Use of these natural resources leads to their depletion. Inexhaustible resources include solar, wind and hydroelectric power, which naturally replenish, or timber and corn, which can be replenished through proper management.Full Answer >
