While the last sixty years have brought many astounding advances in public health and healthcare, in many ways our health has actually gotten worse. Our air and our waterways are generally cleaner, but our own bodies are now filled with chemicals and toxins. We've made driving safer, but we also now drive so much — and walk and bike so little — that adult and childhood obesity have become national epidemics.
The big global sustainability crises also threaten our health in various ways. Climate change promises to bring more extreme weather events, floods and droughts, destroying essential agricultural land and increasing the spread of infectious diseases. Rising costs for fuel will hinder access to health services, and may jeopardize emergency services in some places. Economic crises push people out of jobs, making it harder for them to maintain their health. Looking at the big environmental, social, and economic challenges facing the world today, the threats to public health and our health systems hit closest to home.

In this short video, Brian discusses what inspired him to devote his life to public health and how the realization that energy resources are finite led him to a deeper understanding of what will be the largest public health challenges in the future.
