The Endangered Species Act is the strongest and most effective tool we have to repair the environmental harm that is causing a species to decline.
Norm Dicks

The Englishman wants to be recognized as a gentleman, or as some other suitable species of human being, the American wants to be considered a good guy.
Louis Kronenberger

The fidelity question is difficult for me. Society has made us believe we're supposed to be monogamous when we're not killer whales, or whatever the monogamous species is.
Rachel Hunter

The hierarchy of relations, from the molecular structure of carbon to the equilibrium of the species and ecological whole, will perhaps be the leading idea of the future.
Joseph Needham

The human species really could have faced global thermonuclear war. During seventy years of Cold War we grew used to it.
Larry Niven

The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.
Charles Lamb

The Indian Corn, or Maiz, proves the most useful Grain in the World; and had it not been for the Fruitfulness of this Species, it would have proved very difficult to have settled some of the Plantations in America.
John Lawson

The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed by Most geneticists, but in small founder populations.
Ernst Mayr

The mode of consciousness of nonhuman species is quite different from human consciousness.
J. M. Coetzee

The more you know about a species, the more you understand about how better to help protect them.
Alan Clark

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.
E. O. Wilson

The only way to save a rhinoceros is to save the environment in which it lives, because there's a mutual dependency between it and millions of other species of both animals and plants.
David Attenborough

The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.
Freeman Dyson

The real threat to whales is whaling, which has endangered many whale species.
Dave Barry

The relation of the individual person to the species he belongs to is the most intimate of all relations.
Havelock Ellis

The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them out of clay.
Martin Luther

The sexes in each species of being... are always true equivalents - equals but not identical.
Antoinette Brown Blackwell

The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.
Thomas Huxley

The student who deceives himself into thinking that he is giving his life like an ascetic in the spirit of sacrifice for art, is the victim of a deplorable species of egotism.
Alma Gluck

The thought that we're in competition with Russians or with Chinese is all a mistake, and trivial. We are one species, with a world to win.
George Wald
