How can we make a Blue New Deal? 

Healthy oceans are fundamental to a healthy planet. From phytoplankton, the tiny ocean plants that produce the oxygen we breathe, to the rich diversity of other ocean plants and creatures, we depend on our oceans to survive and thrive.  

But our oceans are both under threat and pose a threat. Pollution, overfishing and the destruction of coral reefs are killing them from within, while the impacts of climate change – rising sea levels and storm surges – are transforming the ocean from friend to foe for the many millions who live on the coast.  

Globally-renowned ocean defender Dr Ayana Elizabeth Johnson is clear: saving the oceans is key to fighting the climate crisis. Join us for a conversation between Ayana Elizabeth Johnson and leading Australian marine scientist Emma Johnston. 

They will explore how these issues are playing out in Australia and internationally, the future of the oceans in the age of climate change, how to mobilise support for a Blue New Deal and how women leaders are pioneering global climate action. 

This event is presented by the UNSW Centre for Ideas and UNSW Science, and the Powerhouse Museum for the 2021 Sydney Science Festival. Supported by Inspiring Australia as a part of National Science Week. Head here to see full program.
