Doris Duke Chair of Conservation Ecology, Duke University; Author, The World According to Pimm: a Scientist Audits the Earth
Pimm's Law
Pimm's First Law
No language spoken by fewer than 100,000 people survives contact with the outside world, while no language spoken by more than one million people can be eliminated by such contact.
Pimm's Second Law
With every change in language (including first contact with humanity), a region's biodiversity shrinks by 20%.
