Above all, we should question the consumer ethic, which uses up non-renewable resources, creates inequality and injustice, generates pollution, destroys other species and upsets the balance of nature. The consumer ethic not only defiles the environment by creating undesirable change in the biosphere but also corrupts the mind and body by defining pleasure in terms of ownership and absorption. Waste itself is a human concept; everything in nature is eventually used. If human beings carry on in their present ways, they will one day be recycled along with the dinosaurs.
