Expertise is no shield against failure to see ahead. Paul Erlich, a brilliant academic who has devoted his entire life to ecological issues, has been wrong in nearly all his major predictions. He was wrong about diminishing resources, he was wrong about the population explosion, and he was wrong that we would lose 50% of all species by the year 2000. His lifelong study of these issues did not prevent him from being wrong.
