Ecosystem Degradation Quotes

Ten percent of the big fish still remain. There are still some blue whales. There are still some krill in Antarctica. There are a few oysters in Chesapeake Bay. Half the coral reefs are still in pretty good shape, a jeweled belt around the middle of the planet. There's still time, but not a lot, to turn things around.

The negative impact of population growth on all of our planetary ecosystems is becoming appallingly evident.

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.

More than one-half of the world's major rivers are being seriously depleted and polluted, degrading and poisoning the surrounding ecosystems, thus threatening the health and livelihood of people who depend upon them for irrigation, drinking and industrial water.

You don't know how to fix the holes in our ozone layer. You don't know how to bring salmon back up a dead stream. You don't know how to bring back an animal now extinct. And you can't bring back forests that once grew where there is now desert. If you don't know how to fix it, please stop breaking it!

The loss of global biological diversity is advancing at an unprecedented pace.

So many technologies start out with a burst of idealism, democratization, and opportunity, and over time, they close down and become less friendly to entrepreneurship, to innovation, to new ideas. Over time, the companies that become dominant take more out of the ecosystem than they put back in.

Even if we act immediately, the world is doomed to lose many of its animal and plant species and this inturn will reduce the ability of ecosystems to deliver vital services to human populations. The Red List gives all of us a practical tool for raising awareness of the biodiversity crisis and for forging new partnerships within the international community.

Development requires modification and transformation of the environment... the planet's capacity to support its people us being irreversibly reduced by the destruction and degradation of the biosphere and the need to understand the problem and take corrective action is becoming urgent.

The body is like the earth ... as vulnerable to overbuilding, being carved into parcels, cut off, overmined, and shorn of its power as any landscape.

The struggle to save the global environment is in one way much more difficult than the struggle to vanquish Hitler, for this time the war is with ourselves. We are the enemy, just as we have only ourselves as allies.

In the Mediterranean of my childhood, there were no large groupers, sharks, or whales. All I saw was seaweed and a few fish, smaller than my little diving mask. All the large animals were gone, simply because we had eaten them.

Some experts look at global warming, increased world temperature, as the critical tipping point that is causing a crash in coral reef health around the world. And there's no question that it is a factor, but it's preceded by the loss of resilience and degradation.

The Baltic Sea is becoming more and more polluted. Not everybody living near the shore of the Baltic Sea is protecting it. It is the water of life for countries like Finland and Sweden.

The essential role of the environment is still marginal in discussions about poverty. While we continue to debate these initiatives, environmental degradation, including the loss of biodiversity and topsoil, accelerates, causing development efforts to falter.

We're finally going to get the bill for the Industrial Age. If the projections are right, it's going to be a big one: the ecological collapse of the planet.

We aren’t exactly emptying the oceans; it’s more like clear-cutting a forest with thousands of species to create massive fields with one type of soybean.

To drown a river beneath its own impounded water, by damming, is to kill what it was and to settle for something else. When the damming happens without good reason . . . then it's a tragedy of diminishment for the whole planet, a loss of one more wild thing, leaving Earth just a little flatter and tamer and simpler and uglier than before.

You've got to spread out as far as you can, cut down a whole forest, irrigate a whole desert, just to make sure that you won't accidentally stumble upon a place that's still in its natural state.

"Clear-cutting" was the word for what the Rusties had done to the old forests: felling every tree, killing every living thing, turning entire countries into grazing land. Whole rain forests had been consumed, reduced from millions of interlocking species to a bunch of cows eating grass, a vast web of life traded for cheap hamburgers. "Look, we're not clear-cutting. All we're doing is pulling out the garbage that the Rusties left behind,” David said. "It just takes a little surgery to do it."

I grew up in an area of a lot of growth, in Orange County, California, and spent most of my youth on the beach. I had witnessed the degradation of our Back Bay and the increased number of closed beach days over the years.

Over the last several decades, human activity have so altered the basic chemistry of the seas that they are now experiencing evolution in reverse to the barren primeval waters of hundreds of millions of years ago.

The world owes an ecological debt to the African continent.

We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation.

I would see my hometown, Los Angeles, change. Green space and orange groves gave way to cement, freeways flooded with traffic, and air pollution, all in the name of "progress." I felt like I was losing my home. It had a profound effect on me, and I realized just how important nature was to my spirit, my soul, my point of view.
