The environmental need for rare earth metals does not mean that every rare earth metals mining project is a net positive for the environment.&lt;p&gt;In particular, this specific mine in Greenland is also a uranium deposit, and could be especially devastating to the environment, at relatively little yield[1]. Greenlanders are correct to be skeptical and concerned (especially given that Greenland Minerals is actually an Australian-Chinese company).&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.rcinet.ca&amp;#x2F;eye-on-the-arctic&amp;#x2F;2021&amp;#x2F;01&amp;#x2F;08&amp;#x2F;canadian-geologist-raises-questions-about-controversial-greenland-mining-project&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.rcinet.ca&amp;#x2F;eye-on-the-arctic&amp;#x2F;2021&amp;#x2F;01&amp;#x2F;08&amp;#x2F;canadian-...&lt;/a&gt;</text><parent_chain><item><author>arsome</author><text>I&amp;#x27;m not too sure one this one - we need rare earths to make things like lithium cells.
