Land resources can be recycled? 10According to the!!!!!!!!!!!!
Renewable natural resources at the present stage of the nature of the specific space and time conditions, can continue to regeneration and regeneration, multiplication and growth, maintain or expand its reserves, depending on the source of renewable.Once the source has disappeared, the resources can not be regenerated, so that the scientific rational use and protection of species source, it is possible to regenerate, it may be inexhaustible". Soil is a renewable resource, because soil fertility can be continuously updated by manual and natural processes. However, there is a non renewable side of the soil, because soil erosion and soil erosion can be much faster than the natural regeneration process of the regenerated soil.
Natural gas, oil, coal, iron ore and other mineral resources are non renewable resources, they use some less, it is impossible to re produce. Taking iron ore as an example, it is a long geological history, which is formed in the Archean era of 26 to 3 billion years. In the ancient times, the metallogenic period was calculated by one hundred million years. On the contrary, the exploitation and consumption of minerals are very fast, and the exploitation period of a mine is only one hundred years, several decades, or even several years. Therefore, from the perspective of human history, mineral resources are non renewable.Ransheng can update by natural or artificial action activities, and called for repeated use of renewable resources, natural resources of human beings, also known as the update of natural resources, such as soil, plant, animal, microorganism and various natural biological communities, forest, grassland and aquatic organism.
Natural resources are those which can be used in the production and life of human beings. Such as water resources, land resources, mineral resources, forest resources, wildlife resources, climate resources and marine resources. These natural resources can be divided into renewable resources and non renewable resources.
Can regenerate.Continuous regeneration and regularly replenished energy called renewable resources can be found in nature, such as hydropower, wind power and solar energy, with the human use and less, the total depletion of energy known as non renewable resources, such as coal, oil and natural gas
