To be fair to Greenpeace, it is actually up to the journalists who talk to Greenpeace to also talk to the targets of their campaigns to get a balanced view. If the companies' typical response is to deny an interview, or to improperly refute information, then the fault lies not with Greenpeace.

I remember flying over eastern Canada to Europe while the US housing boom was getting under way, and I was amazed that it looked like most of the land had been stripped of trees. It was mind boggling that we could not only take down that many trees, but that there were enough humans on the planet to make use of the wood.

So, in my experience, deforestation is indeed a topic which requires some hyperbole.
