Max Campbell is President of the Field Naturalists Club of Victoria (FNCV) and an expert on terrestrial invertebrates. He is also an accomplished photographer and microscopist and had plenty of fascinating photos to illustrate his talk. 
 
Max defines diversity as the variety of all living organisms. He explained that due to the heavy use of fertilisers, pesticides and insecticides, man has unconsciously changed the previously balanced ecosystems that had existed for millennia. He cited the examples of how frogs and many species of insects are vanishing. He also reminded us of the unintended consequences of the introduction of Cane Toads and European Carp.
 
Max highly recommended a book called Slow Death by Rubber Duck: The Secret Danger of Everyday Things. You can read more about FNCV and see more of Max's photos in the Field Nat News..
