What are the renewable resources and which are not renewable resources
Therefore, not only the number of non renewable resources is limited, in a certain time and space scale, the number of renewable resources is limited. In other words, renewable resources are not inexhaustible resources, it is a dynamic concept. Renewable resources only when we control the amount of cases, balancing the exploitation and the resource regeneration, make our development and utilization rate is less than the rate of formation conditions, is "inexhaustible, inexhaustible".
Coal is typical of non renewable resources, it is a non renewable resource is needed because of the formation of long geological history in it, and our people's life cycle is shorter than it, we can't wait till it was formed by the formation of speed ---- it is far greater than the exploitation rate.Renewable resources are natural resources that can be recycled in a short period of time, or can be recycled. Mainly include biological resources (renewable), land resources, water resources, climate resources, etc.. The latter three are renewable resources that can be recycled.
After the development and utilization of human beings, in a very long period of time, it is impossible to regenerate natural resources called non renewable resources. Mainly refers to the nature of a variety of minerals, rocks and fossil fuels, such as peat, coal, oil, natural gas, metal minerals, non-metallic minerals, etc.. This kind of resources is formed in a long period of evolution of the earth, in a certain stage, a certain region, under certain conditions, through the formation of a long geological period. Compared with the development of human society, its formation is very slow, compared with other resources, regeneration rate is very slow, or almost no regeneration. The exploitation and utilization of non renewable resources will be consumed by human beings, and it is impossible to maintain their original reserves or regeneration. Among them, some resources can be reused, such as gold, silver, copper, iron, lead, zinc and other metal resources; others are not to recycle resources, such as coal, petroleum, natural gas and other fossil fuels, when they are used as energy sources and burned, although the energy from one form into in another form, but as the original form of the substance has ceased to exist, its form has changed.
