I just finished watching a BBC three-part series called Generation Earth. It is available on Netflix. It is about the ways humans have altered the planet. With stunning graphics it really shows you what we have done. It talks about the urbanization that has occurred in the last generation, the damming of rivers (all of this being impounded water has actually slowed the rotation of the earth). It shows how we are utterly dependent on copper for all of our modern electrical devices. I never thought about that. It shows the biggest copper mine in the world which is in Utah. What a giant hole in the earth. There is only a tiny percent of copper ore in these limestone rocks, so they take out tons to get a little copper.
I recommend this series to everyone interested in human impact. You can see a short video clip and a summary of the series on the BBC website.
