Respect the delicate ecology of your delusions.
— Tony Kushner

Our personal consumer choices have ecological, social, and spiritual consequences. It is time to re-examine some of our deeply held notions that underlie our lifestyles.
David Suzuki ecological quote

Another key element of human ecology is the inviolability of human life, especially at its beginning and its end. The Holy See insistently proclaims that the first and most fundamental of all human rights is the right to life, and that when this right is denied all other rights are threatened. The assumption that abortion and euthanasia are human rights deserving legislative sanction is seen by the Holy See as a contradiction which amounts to a denial of the human dignity and freedom which the law is supposed to protect. A society will be judged on the basis of how it treats its weakest members; and among the most vulnerable are surely the unborn and the dying.
— Pope John Paul II

It seems to me that there must be an ecological limit to the number of paper pushers the earth can sustain, and that human civilization will collapse when the number of, say, tax lawyers exceeds the world's total population of farmers, weavers, fisherpersons, and pediatric nurses.
— Barbara Ehrenreich

Ecology is rather like sex -- every new generation likes to think they were the first to discover it.
