Matt Ridley is the author of ten books, including most recently, with co-author Alina Chan, Viral: The Search For the Origin of Covid-19. In his third appearance on the podcast (previous appearances: July 7, 2020, and January 4, 2022), Ridley talks about Britain’s energy crisis, why it must begin drilling for gas, the increasing evidence that the Covid pandemic was started by a lab leak, why China’s vaccines haven’t been effective, birds, birdwatching, and why the growing prosperity in Africa gives him hope.
