The cutting of primeval forest and other disasters, fueled by the demands of growing human populations, are the overriding threat to biological diversity everywhere.
Interpretation
Human activities, particularly deforestation, pose a significant threat to biodiversity.
E. O. Wilson's quote highlights the detrimental impact of human population growth and the resultant deforestation on the planet's biological diversity. It suggests that as human populations continue to expand, the demand for land and resources leads to natural habitat destruction, which threatens countless species and ecosystems, ultimately endangering the richness of life on Earth.
In practice
During a lecture on environmental science, one could cite this quote to emphasize the importance of biodiversity.
Consider the nematode roundworm, the most abundant of all animals. Four out of five animals on Earth are nematode worms β if all solid materials except nematode worms were to be eliminated, you could still see the ghostly outline of most of it in nematode worms.
Nature holds the key to our aesthetic, intellectual, cognitive and even spiritual satisfaction.
The worst thing that will probably happen-in fact is already well underway-is not energy depletion, economic collapse, conventional war, or the expansion of totalitarian governments. As terrible as these catastrophes would be for us, they can be repaired in a few generations. The one process now going on that will take millions of years to correct is loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.
Humanity today is like a waking dreamer, caught between the fantasies of sleep and the chaos of the real world. The mind seeks but cannot find the precise place and hour. We have created a Star Wars civilization, with Stone Age emotions, medieval institutions, and godlike technology. We thrash about. We are terribly confused by the mere fact of our existence, and a danger to ourselves and to the rest of life.
Destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal.
An Armageddon is approaching at the beginning of the third millennium. But it is not the cosmic war and fiery collapse of mankind foretold in sacred scripture. It is the wreckage of the planet by an exuberantly plentiful and ingenious humanity.
We might be more inclined to think about the longer term if we were more aware of what is happening around us. Perhaps daily weather forecasts could include a few basic facts about the Earth's vital signs or details of where climate change is increasing the likelihood of damaging weather?
We are on the precipice of climate system tipping points beyond which there is no redemption.
The hole in the ozone layer is a kind of skywriting. At first it seemed to spell out our continuing complacency before a witch's brew of deadly perils. But perhaps it really tells of a newfound talent to work together to protect the global environment.
For myself I hold no preferences among flowers, so long as they are wild, free, spontaneous. Bricks to all greenhouses! Black thumb and cutworm to the potted plant!
The most amazing lesson in aerodynamics I ever had was the day I climbed a thermal in a glider at the same time as an eagle. I witnessed, close up, effortlessness and lightness combined with strength, precision and determination.
To the body and mind which have been cramped by noxious work or company, nature is medicinal and restores their tone. The tradesman, the attorney comes out of the din and craft of the street and sees the sky and the woods, and is a man again. In their eternal calm, he finds himself.
