Carolus Linnaeus Quotes

Hunting, fishing, and trapping is literally perfect. It's the perfect system by which to balance and ground the animal populations for next year's productivity.

Man, who preys both on the vegetable and animal species, is himself a prey to neither. He too possesses the reproductive principle far beyond the degree requisite for the bare continuance of his species. What becomes of the surplus of human life to which this principle is competent?

That the vegetable creation should restore the air which is spoiled by the animal part of it, looks like a rational system, and seems to be of a piece with the rest.

We’re turning everything on the planet into food for humans so we’re cutting down the rainforests, displacing all of the animals, and we’re doing all this to feed humans... ... Imagine if there were only 2 billion people polluting? We’re already overpopulated. I feel we’ve become a parasite on this planet. If this population keeps growing, we’ll just keep devouring the planet, and I don’t think it’s going to stand for that very long.

And I'm wondering where the lions are.

Human beings, because we're so clever, have removed every single one of those population limiting factors... So nothing controls our increase in numbers except our own wish. Since I first started making television programs, the population of the world has increased three times. That's an extraordinary notion. Can it increase four times? Can it increase five times? The Earth is a finite size. So a point will eventually come when we run out of food, when we run out of space and when we will have destroyed most of the natural world. So ought we to do something about it before that happens?

There's this thing that you're not meant to have too many children - for global warming, it's bad. But I know lots of crappy people, and I would rather that good people have lots of kids and outnumber the baddies.

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.

In the grand scheme of nature, I believe that it is very natural that animals eat animals, and that humans eat animals. It is only in the last couple of decades that meat-processing factories have come to rise, and I believe we should take time to reflect on that reality.

The natural inequality of the two powers of population and of production in the earth, and that great law of our nature which must constantly keep their efforts equal, form the great difficulty that to me appears insurmountable in the way to the perfectibility of society.

Overpopulation is the problem of the third and fourth World; over-consumption is the problem of the West. The average American child this year will consume as much of the world's resources as twenty children born in India. Deliberate and calculated waste is the central aspect of the American economy. We over-eat, over-buy, and over-built, spewing out our toxic wastes upon the earth and into the air.

I don't claim to have any special interest in natural history, but as a boy I was made aware of the annual fluctuations in the number of game animals and the need to adjust the cull to the size of the surplus population.

Population control is not an issue involving contraceptives for third world women. It is an issue of ecological justice.

In the history of the world the prize has not gone to those species which specialized in methods of violence, or even in defensive armor. In fact, nature began with producing animals encased in hard shells for defense against the ill of life. But smaller animals, without external armor, warm-blooded, sensitive, alert, have cleared those monsters off the face of the earth.

Human relationships with predators have always been thorny. Predators are the first creatures our kind purposely eradicates. Too often, people feel humans are and should be in control; we are enraged to discover this is not true. And when other creatures share our appetites and kill our livestock (often animals we were raising to kill, ourselves), we call them vandals and murderers...Predators are the most persecuted creatures on Earth.

I am the animal at the head of the pack. … I either get eaten, or I get the good grass.

Without death in the world, existence in it would soon become, through over-population, the most frightful of curses.

I had nixed the idea of having children when I was myself a child, having learned in the 1960s that human overpopulation was literally crowding other species off the planet. Why create another mouth to gnaw at the overburdened earth?

The population of the world is a conditional population; these are not the best, but the best that could live in the existing state of soils, gases, animals, and morals: the best that could yet live; there shall be a better, please God.

Nature can seem cruel, but she balances her books.

The real jewel of my disease-ridden woodlot is the prothonotary warbler. ... The flash of his gold-and-blue plumage amid the dank decay of the June woods is in itself proof that dead trees are transmuted into living animals, and vice versa.

...recognize and respect Earth's beautiful systems of balance, between the presence of animals on land, the fish in the sea, birds in the air, mankind, water, air, and land. Most importantly there must always be awareness of the actions by people that can disturb this precious balance.

We have been God-like in our planned breeding of our domesticated plants and animals, but we have been rabbit-like in our unplanned breeding of ourselves.

Why did God make tigers so good at catching prey, and at the same time make prey so good at getting away from tigers? You'd think that if God wanted one thing or the other to happen he'd have engineered it rather better. Maybe he enjoyed the spectator sport?

‎Using his burgeoning intelligence, this most successful of all mammals has exploited the environment to produce food for an ever increasing population. Instead of controlling the environment for the benefit of the population, perhaps it's time we controlled the population to allow the survival of the environment.
