But despite the fact that they've been proved wrong, the pessimists are undeterred by their abysmal record. They continue to echo a deep-seated fear that unless we repent and change the way we live, we will be instrumental in destroying our own world. Today. industrialisation, genetically modified crops, scientific medicine, nuclear power and the car are held up as the harbingers of doom. Politicians and persuasive pressure groups play on this same basic fear. They scare us with tales of an inevitable global warming catastrophe blamed on CO2 emissions, they stoke the fires of terror that an epidemic of obesity will kill all our children and they sternly tell us that our indulgent lifestyle will consume the earth's precious resources. But will pesticides kill off life in our oceans, will chemicals in food poison us all and invisible rays from power cables and mobiles kill us with cancer? Stanley Feldman, a professor of anaestetics at London University appointed to the Imperial College School of Medicine looks at the evidence. An author of several books, including From Poison Arrows to Prozac, he is a respected lecturer and explainer of popular science.
