| 原材料消费 | raw material consumption The developed countries depend on a stable supply of raw materials for their industries. Total resource requirements are increasing rapidly over the entire world. In developed countries, although population is increasing slowly, per capita use is increasing rapidly, while the opposite is happening in developing countries. Traditionally raw materials have been classified as non-renewable resources, but a distinction may be important between "loosable" resources, such as oil and coal, and "non-loosable" resources, such as metals, which can be used several times over by recycling processes (发达国家依靠原材料为它们的工业提供稳定的材料供给。整个世界总的资源需求增加很快。在发达国家，尽管人口增加很慢，人均使用增加却很快，这和发展中国家相反。传统的原材料属于不可再生资源，"松散的"资源，例如油和煤等和"非松散的"资源，例如金属等区别很大，"非松散的"资源能通过回收重用多次。) |
