For that reason the simple test of the slogan 'Consume Less' as a basis for social action on the environment would be to tell it to the blacks in the ghetto. The message will not be very well received for there are many people in this country who consume less than is needed to sustain a decent life.

The environmental crisis is a signal of this approaching catastrophe.

Perhaps one of the most meaningful ways to sense the impact of the environmental crisis is to confront the question which is always asked about Lake Erie: how can we restore it?
