A Quote by P. D. James

Of the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time.

With respect to phenomena like mass extinction, somebody might say why worry about it because in a geological perspective mass extinctions aren't so bad, they wipe out some things and then 10 million years down the road we get new and interesting objects.But I tell you mass extinctions are really awful for folks caught in the midst of them.

Richard Lewontin

We have come to look at our planet as a resource for our species, which is funny when you think that the planet has been around for about five billion years, and Homo sapiens for perhaps one hundred thousand. We have acquired an arrogance about ourselves that I find frightening. We have come to feel that we are so far apart from the rest of nature that we have but to command.

Marston Bates

Every species becomes extinct; at some point, we will go extinct. The question is, as Homo sapiens, are we going to be able to adapt to the change that we're actually part of? We're causing such dramatic changes to the planet, so yes, you do stop and think, 'I wonder where we're headed.'

Louise Leakey

A billion homo sapiens are added every 11 years to the planet. The hypertrophy of a single species pushes other life-forms out of bed and into extinction. The decline of biological diversity is real and severe. The alarming loss of soil fertility, forest cover, and coral reef viability and the release of fossilized CO2 that nature put away 300 million years ago in its march toward greater diversity - all these "losses" and many others are the result of one life-form annihilating other life-forms in its immoral confusion of "dominion" with "domination."

Leonard Sweet

We, Homo sapiens, destroyed the majority of the large mammalian species in North America and Australasia just over 10,000 years ago. We, Homo sapiens, now are destroying the other species that presently exist on this planet at a rate of about 15,000 to 20,000 per year.

Michael Smith

The right question to ask from a Darwinian prospective is what was it about bipedalism that was so advantageous? Why did it lead to a - why did that adaptation ultimately lead to a species Homo sapiens that has come to dominate the planet today with six and a half billion people?

Donald Johanson

The Earth has been lawned with life for something over 3.5 billion years. That's a span of time great enough to encompass some honest-to-goodness catastrophe. For example, 700 million years ago, Earth underwent a planet-wide deep freeze, with ice covering the oceans from the poles to the equator.

Seth Shostak

The humanity and the humility, which are very different than the biological species homo sapiens. Humanity versus homo sapiens - very different things. We are biological creatures, we are animals, no doubt, but when you talk about "humando," you're talking about that particular kind of animals who are aware of their impending extinction, who have the capacity to be sensitive to catastrophe and disaster and calamity and profound crisis.

Cornel West

The bigger question is how does a rogue species called humans - whose population just blew through the seven billion mark on it's way to nine billion members - manage to survive the next century on a planet with finite resources, without destroying its delicate balance in the process.

Edward Burtynsky

In the last 680 million years of the four and a half billion that this planet has existed, life has been determined by two principal forces: the warmth and the diffused energy of the sunlight coming through our atmosphere, and water. Those are the primordial forces of life - sunlight and water.

Steve Wynn

The technology involved in making anything invisible is so infinitely complex that nine hundred and ninety-nine billion, nine hundred and ninety-nine million, nine hundred and ninety-nine thousand, nine hundred and ninety-nine times out of a trillion it is much simpler and more effective just to take the thing away and do without it.

Douglas Adams

In this way, Edwin Hubble worked out the distances to nine different galaxies. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars.

Stephen Hawking

The planet earth has a life span of eight billion years, give or take a few million. People have been around for approximately forty thousand years-a virtual blink in the cosmos. It is sad that we as a species are ravaging the natural world so fast that we are jeopardizing our survival. If we wipe ourselves out, it would be the height of folly, but the earth will survive even us. It will eventually restore itself. It might take a few thousand years, and it won't be just as it was before, but its life is stronger than death.

Charlotte Sophia Kasl

There is evidence that we are headed into what would be the planet's sixth mass extinction. It's hard to know for sure if you're in one because a mass extinction is an event where over 75 percent of the species on the planet die out over a - usually about a million-year period. The fastest it might happen is in hundreds of thousands of years.

Annalee Newitz

We've been given the gift of a billion years of cosmic time, and we should not screw it up. But at the rate we're using up our planet's natural resources and fouling our own nest means we're not going to last a billion years.

Sandra Faber

Our planet has been around only for four and a half billion years. Let's imagine a planet that has life on it such as life is on Earth and it's seven billion years old. Let's say that planet evolved intelligence. Well, that intelligence would be way more advanced than what we call intelligence here on Earth. How long has intelligence been around on Earth as we've come to define it?
