Species Interdependence Quotes

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.

Crocs are apex predators, and as with all apex predators, they are critical to the environment: if you lose the crocs, you'll lose the barramundi, you'll lose the crabs - a catfish can eat 30,000 barramundi fingerlings, and who do you think eats the catfish? Crocs.

I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer. And perhaps with better cause, for while a buck pulled down by wolves can be replaced in two or three years, a range pulled down by too many deer may fail of replacement in as many decades.

Animals are something invented by plants to move seeds around. An extremely yang solution to a peculiar problem which they faced.

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.

Politicians need a better understanding of global ecology. We need to be freed from our species-specific arrogance. No evidence exists that we are 'chosen', the unique species for which all the others were made. Nor are we the most important one because we are so numerous, powerful and dangerous.

If we continue to address the issue of the environment where we live as though we're the only species that lives here, we'll create a disaster for ourselves.

Biological diversity is the key to the maintenance of the world as we know it... Eliminate one species, and another increases to take its place. Eliminate a great many species, and the local ecosystem starts to decay.

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.

If we were to wipe out insects alone on this planet, the rest of life and humanity with it would mostly disappear from the land. Within a few months.

Both the cockroach and the bird would get along very well without us, although the cockroach would miss us most.

We see them [animals] as the Ice Age is ending and we know that actually in the long run, they're not going to make it. And there's something beautiful about that, beautifully sad. The way the characters are woven together in the film adds to the emotion because they need each other. The message is that it doesn't matter what species you are, you can still love each other and that is a fantastic message.

Our health relies entirely on the vitality of our fellow species on Earth.

Darwin wasn't just provocative in saying that we descend from the apes - he didn't go far enough. We are apes in every way, from our long arms and tailless bodies to our habits and temperament.

While ants exist in just the right numbers for the rest of the living world, humans have become too numerous. If we were to vanish today, the land environment would return to the fertile balance that existed before the human population explosion. Only a dozen or so species, among which are the crab louse and a mite that lives in the oil glands of our foreheads, depend on us entirely. But if ants were to disappear, tens of thousands of other plants and animal species would perish also, simplifying and weakening land ecosystems almost everywhere.

I saw that animals were important. I saw that plants were even more important. I was also to learn that compared to many of the other species, we weren't important at all except for the damage we do. We do not rule the natural world, despite our conspicuous position in it. On the contrary, it is our lifeline, and we do well to try to understand its rules.

There are millions and millions of species, including organisms most people have never heard of. There is so much that waits to be told. We don't know the functions of most of them, but they may be more vital for the planet's future sustainability than we can even dream. And we have to find out; we need to be doing this sort of study.

A forest ecology is a delicate one. If the forest perishes, its fauna may go with it. The Athshean word for world is also the word for forest.

In short, the animal and vegetable lines, diverging widely above, join below in a loop.

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.

If all the insects were to disappear from the earth, within 50 years all life on earth would end. If all human beings disappeared from the earth, within 50 years all forms of life would flourish.

I am decidedly of the opinion that in very many instances we can trace such a necessary connexion, especially among birds, and often with more complete success than in the case which I have here attempted to explain.

If you go far enough back, your genome connects you with bacteria, butterflies, and barracuda - the great chain of being linked together through DNA.

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

Humans are a great survivor species but our survival will be pretty grim if all of the plants and animals we depend on die out. That's why any human survival strategy has to include a plan to maintain our environment roughly in the state that it's in now.
