It's not easy for anyone when the time to put away the car keys is reached: the time when he or she has to relinquish that great worldwide symbol of independence -- driving a car. It happens for some at earlier ages than for others. Sight starts to fail and driving at night becomes increasing difficult. Reflexes slow and the foot moves slower from the gas to the brake.
I've come to believe that even if there was agreement in the U.S. that climate is a key concern, we would do a poor job of addressing the problem. Adversarial solutions will not suffice -- we must learn to hold the tensions of our differences and use this tension to inspire solutions that are better than we have yet imagined.
