Loss of habitat and hunting has pushed the northern white rhino to the brink of extinction. In 1990, there were seven known northern white rhinos. Now, there are only two: a mother, 30, and her daughter, 19. With a million species at risk of extinction, Sir David Attenborough explores how this crisis of biodiversity has consequences for us all, threatening food and water security, undermining our ability to control our climate and even putting us at greater risk of pandemic diseases.
