Earth Day is the first holy day which transcends all national borders, yet preserves all geographical integrities, spans mountains and oceans and time belts, and yet brings people all over the world into one resonating accord, is devoted to the preservation of the harmony in nature and yet draws upon the triumphs of technology, the measurement of time, and instantaneous communication through space.

No society has ever yet been able to handle the temptations of technology to mastery, to waste, to exuberance, to exploration and exploitation... We have to learn to cherish this earth and cherish it as something that's fragile, that's only one, it's all we have... We have to use our scientific knowledge to correct the dangers that have come from science and technology.

The need to find meaning...is as real as the need for trust and for love, for relations with other human beings.

We must have...a place where children can have a whole group of adults they can trust.

Men have always been afraid that women could get along without them.

Humanity . . . lies in man's capacity to question the known and imagine the unknown.

Never ever depend on governments or institutions to solve any major problems. All social change comes from the passion of individuals.
