Dogs may be our best friends, but they are one of the more ecologically destructive species we don't talk about.
Microwaves, how do they work? We find out how they warm up your food, and why it isn't a good idea to stick foil in them.
And we speak to Professor Stewart Frusher from the University of Tasmania about how our already changing climate and warming waters are changing where we find species, and what this means from a social, political and economic point of view.
