" We do not, in thinking about our own lives, simply ask what minimum effort is required of us and then content ourselves with that. In our better moments we try to go beyond that, to exceed the standard, to stretch ourselves and thereby become better people.
We do this as fathers and husbands and mothers and wives. We do this as Christians and Jews and Moslems and Buddhists and Hindus, in our duties to one another and to conscience. We do it in our work and careers, whatever that calling may be. We do it as friends and neighbors. We do it simply as human beings trying to leave our mark in the world, to spread a little love and goodwill where we can. Why should we not also do it as stewards of the earth, the caretakers of creation? "
