Objectivity and activism on the environmental beat

Here's a pertinent read:

Grist Magazine interviewed leading environmental reporters about how they deal with issues of global warming, biodiversity loss, peak oil and other "looming" environmental problems.

"Do they report the facts dispassionately or shift to advocacy? ... To find out, we asked a few."

Those interviewed include Felicity Barringer, The New York Times; Michael Grunwald, The Washington Post; Elizabeth Kolbert, The New Yorker; Andrew Revkin, The New York Times and Ross Gelbspan, author and retired journalist.
