Emily Badger - the writer- appears and writes as a biased source. If you read the other works of her you'll find the common theme of "man and his effect on the planet is evil". If you have a strong view then the outcome a investigation usually supports your presupposed view because that is what you are looking for. More enviro-wacko-wingnut; kalifornia style. Nothing is as bad as you fear or as good as you hope.

edit/note- I'm not saying she is inaccurate in this article- but instead to be justly suspect before taking her word as gospel.
