A Quote by Paul R. Ehrlich
In pushing other species to extinction, humanity is busy sawing off the limb on which it perches.

It's a fair guess that at the rate we're destroying habitat, especially but not exclusively in the tropics, we're pushing to extinction about one species every hour. That doesn't count the species whose populations are being reduced so greatly that diversity within the population is essentially gone.
Many scientists would argue that we are now in what is called Extinction, and it's caused by this perfect extinction storm: climate change, habitat loss, pollution, unsustainable exploitation of species and habitat resources, and of course, human population explosion. All of these factors work together and conspire to drive a species to extinction on our planet, every half an hour.
There is good reason to believe that we have already entered the Sixth Extinction, a period of destruction of species on a massive scale, comparable to the Fifth Extinction 65 million years ago, when three-quarters of the species on earth were destroyed, apparently by a huge asteroid.
With our evolved busy hands and our evolved busy brains, in an extraordinarily short period of time we've managed to alter the earth with such geologic-forcing effects that we ourselves are forces of nature. Climate change, ocean acidification, the sixth mass extinction of species.
A species may eat a particular bacterium, phytoplankton, smaller fish, or plant in an area. Lacking a predator, these species/populations will overgrow and alter the area's biology, overwhelming and driving to extinction dozens or hundreds or thousands of other local species.
The passenger pigeon, the golden toad, the Caspian tiger: they are all gone, and other species hang by a thread. Our actions are not merely driving other species to extinction: we threaten our own survival, too, by destabilising ecosystems and destroying biodiversity.
The humanity and the humility, which are very different than the biological species homo sapiens. Humanity versus homo sapiens - very different things. We are biological creatures, we are animals, no doubt, but when you talk about "humando," you're talking about that particular kind of animals who are aware of their impending extinction, who have the capacity to be sensitive to catastrophe and disaster and calamity and profound crisis.
The earth has continued to change, from rapid climatic changes that have caused the glaciers and the ice sheets to basically bulldoze the landscape and cause species compression in the tropics and cause mass species extinction - you know, all these huge changes. In terms of evolution, every species is doomed to eventual extinction. The natural world is constantly changing. So, to deal with "environmental problems," in quotes, totally misses the issue. That is not the way we want to define our problem if we're going to find our solution.
One animal or plant species may become extinct every hour. All species are doomed to extinction, but man through worldwide development/killing animals for food/profit/using toxic chemicals such as pesticides/industrial wastes, will accelerate the extinction of plants/animals and the result will be a more hostile environment for man.
If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment.
Humanity is part of nature, a species that evolved among other species. The more closely we identify ourselves with the rest of life, the more quickly we will be able to discover the sources of human sensibility and acquire the knowledge on which an enduring ethic, a sense of preferred direction, can be built.
How could being the entire cosmos and all of its wonder and all of its stages and cycles, and yet being that which is beyond them all, the invisible, be extinction? Extinction? The extinction of what, of whom? How can that which has never been be extinguished?
The human heart is not yet so corroded that it can read off the extinction of these two men without a shock to the very roots of its belief in justice and humanity.
I think we must ask ourselves if this is really what we want to do to God's creation, to drive it to extinction? Because extinction really is irreversible; species that go extinct are lost forever. This is not like Jurassic Park. We can't bring them back.
On an overcrowded planet where more species slip toward extinction every day, should one species have the right to multiply and consume at will, even as it nudges others to oblivion?
Suppose you were to come upon someone in the woods working feverishly to saw down a tree.
"What are you doing?" you ask.
"Can't you see?" comes the impatient reply. "I'm sawing down this tree."
"You look exhausted!" you exclaim. "How long have you been at it?"
"Over five hours," he returns, "and I'm beat! This is hard work."
'Well, why don't you take a break for a few minutes and sharpen that saw?" you inquire. "I'm sure it would go a lot faster."
"I don't have time to sharpen the saw," the man says emphatically. "I'm too busy sawing!"
