Many rare minerals are vanishing in urban trash, the humanity does not count the cost the research and development new technology, is substantial clause which the rare minerals reserve drops.

 The rare metal resources are in danger 　　Participated in this item of earth resource inventorying Zelle Pu Richard saying:“each time saw when street sanitation engineer I will become very excited.”Lets the thing which Pu Richard is enthusiastic is trash which actually in these sanitation engineer gunnysack installs, this is because sweeps clear in them from the street in the dirt and the reject is hiding the trace element platinum. 　　The platinum is in the world is scarcest and one of most expensive metals, can urge the exhaust pollutant which the automobile, the truck and the bus discharge to drop to one may accept the level the catalyst. But these year platinum metal has been slowly and drains stably from the transportation vehicle exhaust eductor to the path on.

Scientists estimate that if today is the use of all means of transport 500 million re-equipped with fuel cells, which means that all the world's platinum metal in 15 years can be used up.

And different oil or diamonds, not of metal such as platinum is a chemical element, once we have exhausted all of the platinum, the Earth will no longer have access to platinum approach.

Not only is the world's consumption of platinum metal to speed sounded the alarm. The same thing also happened in many other rare metals on.

Zuhuo materials being used for the manufacture of metal antimony 15 will be used up, silver in 10 years will be depleted, zinc may be used up in 2037, and indium and hafnium these two important raw materials metal computer chips in 2017 , Could be exhausted, used to make fluorescent green phosphor metal terbium in 2012 will be used up before.
