Such as the case with this Ockham's Razor presentation by Professor Paul Sutton from the University of South Australia. He begins with asking the question what would happen 'Kill the bees: why does the market fail to adequately value nature?' then goes on to use economic questioning and statistics where available to respond to this question.
This talk and attached transcript will hopefully prompt economists and policy makers, indeed all of us, to keep the need to adequately value nature in mind.
