Rare earths are threatening technological development
The lack of rare earth metals, used in high-tech electronics, is threatening to push back the rapid growth of many different technologies.

With the rapid growth of technology, the supply of key elements, especially rare earth metals, will be in a state of stress.

Yale University researchers say they have analyzed the use of 62 metals or non-metals commonly found in popular technologies such as smartphones.
The results show that no materials that can represent equivalent 62 metal / non-metal groups can be found.
According to a report published in Proceedings of the National Academy of Sciences , research leader Thomas Graedel said rare earth metals cost a lot of money to exploit and essences, and the processing process always causes serious consequences. important for the environment.
Politics may be a pressure factor for the supply of rare earths, such as China's decision to limit the export of many metals needed for high technology by 2010.
