It's World Environment Day and then World Oceans Day on Tuesday 8th June, with a theme of 'Healthy Oceans, Healthy Planet' - with a big focus on plastics in the oceans and the catastrophic impacts on sealife. In studio we have Neil Blake to talk microplastics, Richard Reina from Monash University to talk about the little penguins at Phillip Island and St Kilda, and Dave Donnelly about whales in Westernport. And our own Dr Beach with marine science, and Bron with the latest in marine news including some good news coming out of San Francisco this week.
