We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.

Wallace Stegner

I am a member of a fragile species, still new to the earth, the youngest creatures of any scale, here only a few moments as evolutionary time is measured, a juvenile species, a child of a species. We are only tentatively set in place, error prone, at risk of fumbling, in real danger at the moment of leaving behind only a thin layer of of our fossils, radioactive at that.

Lewis Thomas

There are 400,000 species of beetles on this planet, but only 8,000 species of mammals.

John B. S. Haldane

Zoologists have reckoned there are up to at least 750 species of animal that have been observed exhibiting same-sex behaviour, or gender role transformation (which is very common in a wide range of fauna). There is only one species on earth, however, which has exhibited homophobia or transphobia. And that is the species homo sapiens sapiens. Us. So let's not allow the foolish, ignorant or bigoted ever to use words like "natural."

Stephen Fry

The reality is that if we in this rich, lucky quarter of the planet cannot make a stand for the 30 million other species we share this planet with, let alone our own species, then who can?

Bob Brown

If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment.

E. O. Wilson

There is part of a structure in which every species is related to every other species. And they're built up on species, like a pyramid. The simpler cell organisms, and then the more complicated ones, all the way up to the mammals and birds and so forth. We call it 'developing upward'... The whole thing depends on every part of it. And we're taking out the stones from the pyramid.

W. S. Merwin

There are millions of different species of animals and plants on earth--possibly as many as forty million. But somewhere between five and fifty BILLION species have existed at one time or another. Thus, only about one in a thousand species is still alive--a truly lousy survival record: 99.9 percent failure!

David M. Raup

We ourselves are part of a guild of species that lie within and without our bodies. Aboriginal peoples and the Ayurvedic practitioners of ancient India have names for such guilds, or beings made up (as we are) of two or more species forming one organism. Most of nature is composed of groups of species working interdependently.

Bill Mollison

A species has to become pretty intellectually advanced in order to grasp the concept of death in the abstract, and to dream up the idea of immortality. Long before that (in evolutionary terms) all species with brains have the survival instinct in some form. So, I am just saying that there are many existent proofs of species that have one, but not the other.

Neal Stephenson

I not only believe, I believe that there are many different species of ships, there are many different species of extraterrestrials, and not all of them are up to good.

Dan Aykroyd

The sooner we become a multi-planet species, the safer the species is, and the stronger the guarantee that we're going to continue to evolve.

Ron Howard

We are the only species on this planet without full employment.

Paul Hawken

Let us beware of saying that death is the opposite of life. The living being is only a species of the dead, and a very rare species.

Friedrich Nietzsche

I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.

Buzz Aldrin

We are the only species on the planet without full employment. Brilliant.

Paul Hawken
