Hurricane Katrina is a wakeup call, not only for the US but for the world. We are entering a period when good science is vital for our survival. On a crowded planet with threats to our climate, oceans, forests, food production, and water supply, and with global travel and high population densities increasing the risk of worldwide disease epidemics, we must turn to the best of our scientific and engineering knowledge to find a safe passage.
Though I was specify further the meaning of 'safe' to include moral and spiritual safety as well, Sach does have a good point. We must make sure that scientific perception is realistically critical and openly honest, never worshipped nor disregarded.
