If it were just a conspiracy theory, someone would have gone through the claims in the book "Viral" by Matt Ridley and Alina Chan and debunked its arguments one by one. Matt Ridley is a journalist who wrote numerous books about scientific topics (one about the genome in 1999). Alina Chan is a biologist who works at Harvard and MIT. When people say "trust the science", or "trust the scientists", why should we trust Peter Daszak, with his obvious conflicts of interests, over Alina Chan?
