Laurance ends his article by stating his philosophical position on scientific uncertainty:
Tropical forests and their biota are facing an enormous array of anthropogenic threats. As scientists, we are obliged to evaluate even pressing environmental issues objectively. But, as realists, we must also appreciate that certain political interests and authors actively embrace scientific uncertainty (e.g. Lomborg and Crichton) in an effort to advance their particular agendas. It is because of such concerns that I have critiqued the thought-provoking Wright and Muller-Landau study, for I believe it seriously understates the tropical biodiversity crisis.
