Quotes About Ecology

Wars don't happen on battlefields; they go on happening in people's hearts for generations and generations, and the ecological damage is unfathomably complex and dire.

Estuaries are coastal bays, harbors, sounds and lagoons, places where rivers meet the sea.

I'm just a simple man from Bolton but I think we should use more natural sources.

Every time you think of a city, you have to think green, green, green. Every time you see concrete jungle, you must find open spaces. And when you find open spaces, make it so people can get to them.

The science is clear: to solve the climate crisis, we must protect our natural spaces.

that the burden of evidence is on those who disturb natural systems

Nature's success stories, they are like Gause's protozoans; the world is their petri dish. Their populations grow at a terrific rate; they take over large areas, engulfing their environment as if no force opposed them. Then they hit a barrier. They drown in their own wastes. They starve from lack of food. Something figures out how to eat them.

Even with slash-and-burn, ecologists say, the forest can take as much as a hundred years to return completely to its previous state. European-style agriculture would not only fall victim to mega-Niños, it would permanently ruin the forest soils.

Likely the milpa cannot be replicated on an industrial scale. But by studying its essential features, researchers may be able to smooth the rough ecological edges of conventional agriculture. "Mesoamerica still has much to teach us," Wilkes said.

According to Peter Stahl, an anthropologist at the State University of New York in Binghamton, "lots" of researchers believe that "what the eco-imagery would like to picture as a pristine, untouched Urwelt [primeval world] in fact has been managed by people for millennia.

More important, the very existence of so much healthy forest after twelve thousand years of use by large populations suggests that whatever Indians did before swidden must have been ecologically more sustainable.

The Columbian Exchange was neither fully controlled nor understood by its participants, but it allowed Europeans to transform much of the Americas, Asia, and, to a lesser extent, Africa into ecological versions of Europe, landscapes the foreigners could use more comfortably than could their original inhabitants.

One of the penalties of an ecological education [Leopold later wrote] is that one lives alone in a world of wounds. Much of the damage inflicted on land is quite invisible to laymen. An ecologist must either harden his shell or make believe that the consequences of science are none of his business, or he must be the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise.

The natural world is incomplete without the human touch.

it suggests that for a long time clever people who knew tricks that we have yet to learn used big chunks of Amazonia nondestructively. Faced with an ecological problem, the Indians fixed it. Rather than adapt to Nature, they created it. They were in the midst of terraforming the Amazon when Columbus showed up and ruined everything.

the forest islands of Bolivia are comparable to any place in South America. The same is true of the Beni savanna, it seems, with its different complement of species. Ecologically, the region is a treasure, but one designed and executed by human beings. Erickson regards the landscape of the Beni as one of humankind's greatest works of art, a masterpiece that until recently was almost completely unknown

the very existence of so much healthy forest after twelve thousand years of use by large populations suggests that whatever Indians did before swidden must have been ecologically more sustainable.

Tree planting, advocates say, is simpler and less risky than high-tech Wizardly schemes.

Passenger pigeons were greedy eaters with terrible manners; if they found some food they liked just after finishing a meal, they would vomit what they had previously eaten and dig in. Gobbling their chow, they sometimes twittered in tones musical enough that people mistook them for little girls. They gorged on so many beechnuts and acorns that they sometimes fell off their perches and burst apart when they hit the ground.

Rather than the thick, unbroken, monumental snarl of trees imagined by Thoreau, the great eastern forest was an ecological kaleidoscope of garden plots, blackberry rambles, pine barrens, and spacious groves of chestnut, hickory, and oak. The first Europeans in Ohio found woodlands that resembled English parks—they could drive carriages through the trees.

Now, these were hungry people who were very interested in acquiring protein. The simplest explanation for the lack of passenger pigeon bones is a lack of passenger pigeons. Prior to 1492, this was a rare species.

Nonetheless, ecologists and archaeologists increasingly agree that the destruction of Native Americans also destroyed the ecosystems they managed. Throughout the eastern forest the open, park-like landscapes observed by the first Europeans quickly filled in. Because they did not burn the land with the same skill and frequency as its previous occupants, the forests grew thicker. Left untended, maize fields filled in with weeds, then bushes and trees.

European and U.S. environmentalists insist that the forest should never be cut down or used—it should remain, as far as possible, a land without people. In an ecological version of therapeutic nihilism, they want to leave the river basin to its own devices. Brazilians I have encountered are usually less than enthusiastic about this proposal.

Because they did not burn the land with the same skill and frequency as its previous occupants, the forests grew thicker. Left untended, maize fields filled in with weeds, then bushes and trees. My ancestor Billington's great-grandchildren may not have realized it, but the impenetrable sweep of dark forest admired by Thoreau was something that Billington never saw. Later, of course, Europeans stripped New England almost bare of trees.
