Species Extinction Quotes

Wild animals never kill for sport. Man is the only one to whom the torture and death of his fellow creatures is amusing in itself.

Here in the United States we turn our rivers and streams into sewers and dumping-grounds, we pollute the air, we destroy forests, and exterminate fishes, birds, and mammals—not to speak of vulgarizing charming landscapes with hideous advertisements.

For the most part we don’t have an immediate impact on the species that surrounds us. But we do have an immediate impact on their habitat which determines whether they survive on in some cases shift their ground.

If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos.

The cutting of primeval forest and other disasters, fueled by the demands of growing human populations, are the overriding threat to biological diversity everywhere.

Adapt or perish, now as ever, is nature's inexorable imperative.

Genetic pollution is considerably more dangerous than oil spills. You can’t just go out there and put a boom around it and put it back in.

Human activity is having a major impact on the planet. We consume or have diverted a large proportion of the productivity of the land and oceans. Our hunger for land crowds out fellow species. Our waste products pollute the waters, warm the atmosphere and acidify the oceans.

Humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel. This has resulted in a substantial and largely irreversible loss in the diversity of life on Earth.

The solutions like freezing zygotes, fertilized eggs, of all kinds of animals and so on, or keeping them in zoos and having arboreta where we have trees, all these things have been promoted. Even getting the complete genetic code of various fishes so we can let them pass away and then we'll pull them back. That is science fiction run amok.

If man doesn't learn to treat the oceans and the rain forest with respect, man will become extinct.

If we we were to intentionally set out to cause the extinction of a species, we should think about that. I would want there to be some consideration and reflection of a social consensus before we take that step.

I believe in helping the planet survive, and that includes reaching out to help some of the disappearing creatures whose habitats we're destroying. It's up to us to somehow reverse that trend. I don't know how we'll achieve it, but we need to.

Although biodiversity loss continues globally, many countries are significantly slowing the rate of loss by shoring up protected natural areas and the services they provide, and in expanding national park systems with tighter management and more secure funding.

People say I am against Darwin. That is ridiculous.

There are two problems for our species' survival - nuclear war and environmental catastrophe - and we're hurtling towards them. Knowingly.

As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.

The classical argument for why a supposedly decent and moral creature like Homo sapiens can mistreat and even extirpate other species rests upon an extreme position in a continuum. The Cartesian tradition, formulated explicitly in the seventeenth century, but developed in "folk" and other versions throughout human history no doubt, holds that other animals are little more than unfeeling machines, with only humans enjoying "consciousness," however defined.

If we destroy the biosphere, then mankind will die. We all waste our time worrying about stupid wars and petty jealousy and greed, and all the time, we're sitting on a time bomb.

People will be able to survive, of course, without honeycreepers and monk seals. But if the wolf spider is in trouble, we are in trouble, too.

In a free market and in the absence of planning, developers will flatten every hillside, fill every canyon, obliterate every endangered species, and pave over every wetland they think they can make a buck on.

Tropical rain forests, as well as tropical and temperate dry forests, are being destroyed rapidly. At present rates, some critical forest types will be gone in a few years, and most of the tropical rain forest will be gone before the end of the next century. With them will go large numbers of plant and animal species.

We have killed off nature, that world entirely independent of us which was here before we arrived and which encircled and supported our human society

Humans regard animals as worthy of protection only when they are on the verge of extinction.

Sharks have swum the oceans for over 400 million years, but we're threatening this critically important species for the purpose of making soup - it's sad and wasteful.
