Quotes About Ecosystem

On Cape Cod, great white shark stocks have been growing, or at least becoming more concentrated, because of the multiplying numbers of seals around Monomoy Island. We are fortunate to have such abundance of these sharks in our own waters. Around the globe, we are killing in excess of 100 million sharks each year.

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.

We'll lose more species of plants and animals between 2000 and 2065 than we've lost in the last 65 million years. If we don't find answers to these problems, we're gonna be victims of this extinction event that we're at fault for.

I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.

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.

Zebra mussels like to hitch a ride on boats when they're transferred from one body of water to another. It's important to make sure to thoroughly clean your boat each time it leaves the water to ensure these invasive mussels are removed and that you are not spreading them to your next location.

We're not the only mammals who are partial to blackberries, far from it. Foxes and badgers will also gobble them up, helping to distribute the seeds, which survive the transit through the gut.

I don't think we're going to save anything if we go around talking about saving plants and animals only; we've got to translate that into what's in it for us.

It feels like an easy sum to gauge the balance between forests and, say, the proliferating free newspapers that litter our public transport. This noxious combination of words and paper represents a clear-cut crime against the biosphere.

Globally, 12 percent of bird species, 23 percent of mammals, and 32 percent of amphibians are at risk of extinction. Since 1970, global populations of these creatures have declined by nearly 30 percent. Just how these losses will shift the distribution of microbes between and across species, pushing some over the threshold, remains to be seen.53

a single opossum, through grooming, destroyed nearly six thousand ticks a week.

As avian diversity declined in the United States, specialist species like woodpeckers and rails disappeared, while generalist species like American robins and crows boomed. (Populations of American robins have grown by 50 to 100 percent over the past twenty-five years.)48 This reordering of the composition of the local bird population steadily increased the chances that the virus would reach a high enough concentration to spill over into humans.

Even in the vast and mysterious reaches of the sea we are brought back to the fundamental truth that nothing lives to itself.

People worry about losing species diversity in the rain forest. But what about intellectual diversity-our most necessary resourse?

People who imagined that life on earth consisted of animals moving against a green background seriously misunderstood what they were seeing. That green background was busily alive. Plants grew, moved, twisted, and turned, fighting for the sun; and they interacted continuously with animals—discouraging some with bark and thorns; poisoning others; and feeding still others to advance their own reproduction, to spread their pollen and seeds.

Broadly speaking, the ability of the park to control the spread of life-forms. Because the history of evolution is that life escapes all barriers. Life breaks free. Life expands to new territories. Painfully, perhaps even dangerously. But life finds a way.

the natural world had gone badly wrong. Everything that mankind is doing on the planet had upset the delicate balance of nature. The pollution, the rampant industrialization, the loss of habitat-when animals were squeezed and cornered, they behave viciously, in a desperate effort to survive.

Human beings are so destructive,' Malcolm said. 'I sometimes think we're a kind of plague that will scrub the earth clean. We destroy things so well that I sometimes think, maybe that's our function. Maybe every few eons, some animal comes along that kills off the rest of the world, clears the decks, and let's evolution proceed to its next phase.

It was interesting that the compys only ate fresh dung

You know, at times like this one feels, well, perhaps extinct animals should be left extinct. Don't you have that feeling now?

This disaster was caused by environmentalists charged with protecting the wilderness, who made one dreadful mistake after another—and, along the way, proved how little they understood the environment they intended to protect.

The lion does not constantly war with the leopard; the horse does not war with the cow; even among themselves they rarely kill each other, no matter how important the issue to them." "But they would," said Count Roldero, undaunted. "They would if they could anticipate events. They would if they could work out the rate at which the rival animal is consuming food, breeding, expanding its territory.

More grass means less forest; more forest less grass. But either-or is a construction more deeply woven into our culture than into nature, where even antagonists depend on one another and the liveliest places are the edges, the in-betweens or both-ands..... Relations are what matter most.

You are what you eat is a truism hard to argue with, and yet it is, as a visit to a feedlot suggests, incomplete, for you are what what you eat eats, too. And what we are, or have become, is not just meat but number 2 corn and oil.
