Professor Mark Costello - when is a species not a species?

From Karyn Hay Presents: Queen's Birthday, 10:32 am on 3 June 2019

Mark Costello is an Auckland University marine ecologist, who co-leads the most comprehensive global stocktake of the marine life of the world's oceans which has enabled scientists to name all but half a million of all marine species. Professor Costello says the Marine Biodiversity Observation Network shows the UN's recent report on biodiversity is based on a vastly exaggerated estimation of how many species there are on the planet. He will be one of the lead authors on a chapter on oceans and biodiversity in the next tranche of the IPCC's report on global warming.
