This article justifies one purpose of my research. Since my research is to make a less efficient air-conditioner that more efficiently utilisies metal resources, I’m going to use this article as a reference in my next report.
New study raises questions about sustainability of metal resources from PhysOrg.com
Researchers studying supplies of copper, zinc and other metals have determined that these finite resources, even if recycled, may not meet the needs of the global population forever. According to the study, if all nations were to use the same services enjoyed in developed nations, even the full extraction of metals from the Earth’s crust and extensive recycling programs may not meet future demand.
