"The technology of spears and digging sticks transformed us from quadrupedal into bipedal animals. The technology of fire and cooking resulted in the loss of our body hair, a massive expansion in the size of our brains, and the disappearance of our tree-climbing anatomy. The technology of clothing and shelter enabled us to migrate out of the tropics and made it possible for our 'premature' newborns to survive in cold climates. And the technology of symbolic communication involved significant changes in our brains, freeing us from the pace of biological evolution and enabling us to take advantage of the speed and flexibility of cultural evolution... When the technology of agriculture made it possible for humanity to produce its own food and store it for the future, our species cast off a burden that it had borne, along with all other animals, since its beginning.
Unbound from the daily search for food, our ancestors settled down in permanent settlements composed of hundreds and even thousands of people, learned to specialize in arts and crafts, and began to multiply. New and powerful technologies of transportation and communication enabled us to build cities and multiply still more, creating enormous civilizations composed of hundreds of thousands of people. The technology of precision machinery made it possible for us to create modern industrial nation-states composed of millions, and as a result we have multiplied so fast that our long-term future is now at risk. And the recent development of digital technology - which enables us to trade, visit, and communicate with all members of the human species - has made it possible, for the first time in our history, for humanity to fuse into a single global society."
"We humans are no longer a species of simple hunters and gatherers living within the constraints of a stable natural world. Instead, freed from many of our natural limitations by the relentless progress of technology, we have become the unbound masters of the biosphere."
"The full story of the sixth mass extinction is still to be written. We may yet hope for a happy ending."
