No one knows the diversity in the world, not even to the nearest order of magnitude. ... We don't know for sure how many species there are, where they can be found or how fast they're disappearing. It's like having astronomy without knowing where the stars are.
Interpretation
The quote highlights the vast unknowns about global biodiversity and the urgency of understanding it.
E. O. Wilson emphasizes that our knowledge of the countless species inhabiting the Earth is alarmingly limited. Despite the critical importance of biodiversity to ecosystems and human existence, we struggle to quantify the magnitude of species diversity, their habitats, and the threats they face. This lack of knowledge mirrors the confusion of attempting to study astronomy without a map of the stars, underscoring the necessity of increased awareness and research in the field of biodiversity conservation.
In practice
In a conservation conference, when discussing the urgent need for biodiversity awareness.
Consider the nematode roundworm, the most abundant of all animals. Four out of five animals on Earth are nematode worms — 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.
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
Follow the evidence wherever it leads, and question everything.
I am not accustomed to saying anything with certainty after only one or two observations.
It {Darwin's theory of evolution] was a concept of such stunning simplicity, but it gave rise, naturally, to all of the infinite and baffling complexity of life. The awe it inspired in me made the awe that people talk about in respect of religious experience seem, frankly, silly beside it. I'd take the awe of understanding over the awe of ignorance any day.
When the space shuttle's engines cut off, and you're finally in space, in orbit, weightless... I remember unstrapping from my seat, floating over to the window, and that's when I got my first view of Earth. Just a spectacular view, and a chance to see our planet as a planet.
Even if there were no actual evidence in favor of the Darwinian theory, we should still be justified in preferring it over all rival theories.
