[The natural world cleans water, pollinates plants and provides pharmaceuticals, among many other gifts.] Thirty trillion dollars worth of services, scot-free to humanity, every year.
Interpretation
The natural world provides invaluable services to humanity without any cost.
E. O. Wilson highlights the immense and often overlooked contributions of the natural world to human existence, such as cleaning water, pollinating plants, and supplying medicinal resources. He emphasizes that these ecological services, valued at around thirty trillion dollars annually, are provided freely, underscoring the importance of preserving and valuing nature for its essential role in sustaining life.
In practice
In a speech about climate change, one could use this quote to emphasize the importance of preserving natural ecosystems.

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.

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 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.
When we plant trees, we plant the seeds of peace and seeds of hope.
The sun was a toddler insistently refusing to go to bed: It was past eight thirty and still light.
It gradually became clear that the Green Belt Movement's work with communities to repair the degraded environment could not be done effectively without participants embracing a set of core spiritual values.
You either get the point of Africa or you don't. What draws me back year after year is that it's like seeing the world with the lid off.
Our modern industrial economy takes a mountain covered with trees, lakes, running streams and transforms it into a mountain of junk, garbage, slime pits, and debris.
It was one of those March days when the sun shines hot and the wind blows cold: when it is summer in the light, and winter in the shade.
