Sustainable Development

A renewable resource can be produced or replaced by a healthy ecosystem can be produced or replaced by a healthy ecosystem. A nonrenewable resource is when a natural process cannot replenish them within a reasonable amount of time. Fossil fuels (coal, oil, and natural gas) are nonrenewable resources. Sustainable development provides for human needs while preserving the ecosystems that produce natural resources. Sustainable development doesn't cause harm to soil, water, and climate. It also consumes little energy and material as possible.

Using Resources Wisely

Soil, water, and air are all important resources.

Soil

Soil is important because it supports both agriculture and forestry. If people leave farmland barren between plantings, the soil can easily be eroded. Nutrients and minerals can also be carried off with the soil, when soil is badly eroded. Desertification is when farmland turns into a desert. This can happen by a combination of dry climates, farming, overgrazing, seasonal drought, and climate change. Deforestation is the loss of forests and trees. This also have a negative effect on the quality of soil. The roots of plants help hold soil in place so it doesn't get eroded. Forests also protect the quality of fresh water supplies, absorb carbon dioxide, and help moderate local climate. Soil erosion can be minimized through careful management of both agriculture and forestry.

Water

Water is important for many things. Some examples are drinking, bathing, washing, industry, transportation, energy, and waste disposal. Water is also needed for farming. If water is polluted then this can affect the food we eat and many other things. Primary sources of water pollution are industrial and agricultural chemicals, residential sewage, and non-point sources (pollutants from small sources such the grease and oil washed off streets by rain or chemicals released into the air by factories and automobiles). Biological magnification occurs id a pollutant such as DDT or mercury is taken in by an organism and is not broken down from its body. To protect water from pollution, protecting the natural systems involved in the water cycle with help.

Air

Common forms of air pollution are smog, acid rain, greenhouse gases, and particulates. Smog is a gray-brown haze formed by chemical reactions among pollutants released into the air by industrial processes and automobile exhaust. Acid rain results from the chemical transformation of nitrogen and sulfur products that come from human activities. This harms plants. Greenhouse gases are carbon that is released from burning fossil fuels and forests. Particulates are microscopic particles of ash and dust released by certain industrial processes and certain kinds of diesel engines. It is hard to improve air quality. Usually people try to make new engines and other things that don't give off as much emissions.

Value of Biodiversity

Biodiversity is the total of all the genetically based variation in all organisms in the biosphere. Biodiversity's benefits to society include contributions to medicine and agriculture, and the provision of ecosystem goods and services. Biodiversity is important because many different organisms are used for resources that support life.
