This week on Green Desk Mangrove Mitch koreros with Shark Scientist Riley Elliot about the global decline in shark populations. Riley and Mitch discuss the recent decision made by New Zealand to vote no against the protection or Mako Sharks at CITES and the change in behaviour that he has seen in sharks as a result of human impacts on their environment. To begin, Mitchell asks Riley about the role sharks play as apex predators and how important they are to our global ecosystems.
