That passion is fueled by the increasingly serious problems such as climate change, biodiversity loss and ocean resource degradation facing us all. Adding to this passion is the responsibility he feels for the children who will inherit this world after our generation is gone. This, and the knowledge, skills and contacts he has accumulated during his career makes him an effective member of the Executive Committee. 

David is the President of the George Wright Society (GWS) (georgewrightsociety.org), a long-time institutional member of IUCN.
