To the editor:
Earlier this year, the Intergovernmental Panel on Climate Changes predicted the average global temperature will rise between 2.4 and 10.4 degrees Fahrenheit this century much more than previously expected. Although humanity did not understand the enironmental consequences 100 years ago when we chose energy and transportation technologies that rely on fossil fuels, today we do, and we must, make better choices if we want to avert an era of wars, terrorist and environmental disasters of global proportions.
Increasing our use of renewable fuels, in place of fossil fuels, would be an important step in the right direction. We must avoid letting tragedies that are a spin-off of failed energy and foreign policies, such as we have recently seen in the east, divert our attention away from their root causes. We must begin fighting these root causes of terrorism rather than focus all our attention and resources on fighting terrorism alone. When the tub overflows, turning off the faucets is as important as the mopping up.
