Express support for mining as a source of jobs and resources, but express concern about the potential environmental impact of leaving behind a lake or pond full of poisonous fluids. Express disbelief that some people are willing to accept this as a solution.
Mining can be a great thing, providing jobs and much-needed raw materials for our country.  Help make America great again and all that...  
I am all for this project as long as it does not involve a lake full of poisonous fluid.  Especially one that will be left behind forever.  Oh.  I see.  It will be a small pond, right?  Oh.  I see.  But they plan on taking it with them when they go.  Oh.  Um...  No way of cleaning that up?  And there are people okay with that idea?  Really?  Wow.  Guess their right... Can't fix stupid.
