The Circle for Human Sustainability's Founding President, Catherine Loke, takes us on a journey to explore where materials come from, how we are reliant on energy for every aspect of our lives, economics and human values, and what we can do to prepare ourselves for a low-energy future.

This talk was a guest lecture given in February 2022 for the NUS ME6509 Materials and Sustainability course conducted by Prof Seeram Ramakrishna.
