Lasrick writes: Fred Guterl is the executive editor of Scientific American, and in this piece he explores various real threats posed by technology that modern civilization relies on. Discusses West African and Indian monsoons, infectious diseases, computer hacking. Here's a quote: "Today the technologies that pose some of the biggest problems are not so much military as commercial. They come from biology, energy production, and the information sciences — and are the very technologies that have fueled our prodigious growth as a species. They are far more seductive than nuclear weapons, and more difficult to extricate ourselves from. The technologies we worry about today form the basis of our global civilization and are essential to our survival."
