The Australian Climate Diet

Presented by Powerhouse

With the world’s population expected to reach 10 billion people by 2050, how will the science behind our food production systems change to meet our growing demands? How will it tackle issues of climate change and sustainability? And what benefits will transforming our modern food system have on the environment and human health?

These and other thought-provoking questions will be examined by the Climate Feast discussion panel at the 2021 Sydney Science Festival. Guided by the Powerhouse’s Creative Industries Resident, Kate Cox, our experts will share insight into how the food we eat impacts the environment; the changes we need to make today for global food security in the future; and what might be on our plates tomorrow.
