Earth's Limited Supply of Metals Raises Concern
Go to the store and buy a pumpkin- paint it in the form of the earth- blue
for oceans, green for continents. Find a needle and pry out a piece- that's
the amount of natural resources used in all of human history- now wipe the
piece in the blue part- thats all the pollution .

Where's all that stuff going- somebody shooting it out into space?
No, it's rusting in the form of steel cars, metal structures, bridges,
etc.
It's burning in the form of sodium-vapor streetlamps, solid rocket fuel,
refinery operations, etc.
One of the primary laws of physics is that matter cannot be created or
destroyed... so the metals aren't going anywhere, only being converted
into
stuff which is unusable.
