An American doctor is warning a plague that could decimate half the world's population might be around the corner, and it would make coronavirus look like child's play.
Dr Michael Greger, a scientist who advocates the health benefits of a plant-based diet, has penned a new book called 'How to Survive a Pandemic'.
He says our obsession with animals, from keeping them as pets to hunting them for sport to turning them into burgers, makes human beings incredibly vulnerable to infectious diseases. "Zoonoses" are infections that pass from animals to humans, like how coronavirus likely spread to customers from livestock at a Wuhan wet market.
