As we descend deeper and deeper in this region its inhabitants become more and more modified, and fewer and fewer, indicating our approach towards an abyss where life is either extinguished, or exhibits but a few sparks to mark its lingering presence.
We still have 10 percent of the sharks. We still have half of the coral reefs. However, if we wait another 50 years, opportunities might well be gone.
Seasonally ploughing and harvesting crops will mash up a few moles, slice through a burrow of field mice and crush any ground-nesting bird chicks. Far more significant, however, is the creation of the field in the first place: an act that replaces entire ecosystems, along with all their animal inhabitants.
Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are laid waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.
The world is now on track to more than double current greenhouse gas concentrations in the atmosphere by the end of the century. This would push up average global temperatures by three to eight degrees Celsius and could mean the disappearance of glaciers, droughts in the mid-to-low latitudes, decreased crop productivity, increased sea levels and flooding, vanishing islands and coastal wetlands, greater storm frequency and intensity, the risk of species extinction and a significant spread of infectious disease.
An now the silences come in a single lifetime, in a single year... when species die, leaving a silent space in the world song that can never be filled.
Where do we record the passing of wildlife? Who mourns the silent deaths of the small?
Worldwide, enormous areas of peatland are still being lost to agricultural development, drainage schemes, overgrazing, and exploitation-based infrastructure development projects such as roads, electricity pylons, telephone masts and gas pipelines.
When I consider that the noble animals have been exterminated here - the cougar, panther, lynx, wolverine, wolf, bear, moose, deer, the beaver, the turkey, etc, etc - I cannot but feel as I lived in a tamed, and, as it were, emasculated country.
Historically, grizzlies ranged from Alaska to Mexico, with at least 50,000 bears living in the western half of the contiguous United States. With European colonization, the bears were shot, poisoned, and trapped to the brink of extinction.
An awful lot of England is slowly eroding, in ways that I find really distressing, and an awful lot of it is the hedgerows... We're reaching the point where a lot of the English countryside looks just like Iowa - just kind of open space.
An asteroid can literally destroy 80 or 90 percent of the species that are alive on Earth. These are big events. I mean, this is called extinction.
Global climate change has become entangled with the problem of invasive species. A warmer climate could allow some invaders to spread farther, while causing native organisms to go extinct in their traditional habitats and making room for invaders.
What were several fewer species of animals compared with a hundred-mile advance and another medal on another general?
Since woodchipping began 32 years ago, Tasmanians have watched as one extraordinary place after another has been sacrificed. Beautiful places, holy places, lost not only to them, but forever.
It wont be long now it wont be long man is making deserts of the earth it wont be long now before man will have used it up so that nothing but ants and centipedes and scorpions can find a living on it.
Endangered forests are being slaughtered for toilet paper.
In a few generations more, there will probably be no room at all allowed for animals on the earth: no need of them, no toleration of them.
I am truly sorry that a fowl of Canada is no longer with us.
Many of the environmental rules not only fail to protect the natural environment, they actually increase the damage.
The vast majority of species that are vanishing, we haven't even discovered yet. How can you possibly put them back in nature if the ecosystem is gone?
Wildlife of the world is disappearing, not because of a malicious and deliberate policy of slaughter and extermination, but simply because of a general and widespread ignorance and neglect.
I have lived long enough to witness the vanishing of wild mammals, butterflies, mayflies, songbirds and fish that I once feared my grandchildren would not experience: it has all happened faster than even the pessimists predicted.
