In the second of this year’s Reith Lectures, recorded for the first time in Wales in its capital city Cardiff, Martin Rees, President of the Royal Society and Astronomer Royal, continues to explore the challenges facing science in the 21st Century.
Our planet is coming under increasing strain from climate change, population explosion and food shortages. As we use up our natural resources ever more quickly, how can we use science to help us solve the crisis that we are moving rapidly towards?
We need international consensus, and global funding for clean and green technologies. The challenge, for scientists, governments and people everywhere, is to confront the threats to our planet and find the solutions in science.
