An estimated five trillion plastic items - mostly less than five millimetres in size - are currently circulating the surface of the world's oceans and scientists cite microplastics (particles less than 5mm) entering our food chain as a potential toxic ticking time bomb. Let that sink in for a minute... ('scuse the pun).
Three experts in waste, microplastic contamination research and consumer behaviour, Vaughan Levitzke, Vivian Sim, and Anne Sharp sit down with the ABCs Deb Tribe to discuss the scale of the world's addiction to plastic and the possible solutions.

Is colonising Mars the next giant leap for humanity or is it a waste of time and money? Do humans need to be a multi planet species to avoid extinction as argued by Elon Musk? What have humans and the blue planet got to gain in the short term by practising and preparing to inhabit the Red Planet? Who better to ask than two of our favourite Martians, Australian Mars One candidate, Josh Richards and Carmel Johnston – Crew Commander of a year-long Mars Simulation mission.
Speakers: Tom Wigley | Steffen Lehmann | Amie Albrecht

Thanks to the latest research from a host of the world’s most respected climate scientists like Tom Wigley, the weight of evidence pointing to the human role in changing our weather is now beyond compelling. Consequently, if their forecasts of climate change increases do occur, life in our most densely populated areas face an unprecedented and urgent call to action.
With 26 cities on the planet currently housing between 10 and 20 million people each and projections of a future with 11 billion people on the planet including the first 100 million person cities, this panel looks at up to date research on how and why our climate may change and how our built environs and transport systems must adapt to accommodate life in future mega cities.
