Provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

How did the dinosaurs die? They were the biggest, most powerful animals that ever walked the earth. Now they are all gone--extinct. Sixty-five million years ago, a giant asteroid slammed into Earth, with devastating effects. Paleontologist Charlotte Lewis Brown and artist Phil Wilson recreate what may have happened to the dinosaurs on that deadly day.

Twelve-year-old twins Nick and Eryn investigate why their mother and new stepfather are keeping secrets, why they are forbidden to meet their stepsiblings, and most important, why their lives are in danger.

Investigates what would happen if every single person on Earth simply disappeared. The Earth would be a world where city streets would still be populated by cars, but without drivers. Nobody to fix bridges, repair buildings, or maintain power facilities. After being controlled by humanity for millennia, the Earth would be reclaimed by nature. See how long skyscrapers and our homes would last if abandoned.

Twelve-year-old twins Nick and Eryn and their robot stepsiblings, Jackson and Ava, try to save humanity from killer robots.

The tiger is just one of thousands of animals--including the ground iguana, the white-rumped vulture, and the partula snail--currently in danger of becoming extinct, joining the dodo, the marsupial wolf, the great auk, and countless others we will never see again.

"Asteroids come in all shapes and sizes--and hit our planet in them, too. But what happens if a catastrophically large one approaches earth? By looking on the ground at historical asteroid craters and present-day falls, and up into space for the big ones yet to come, a wide variety of scientists are trying to figure out how to track asteroids--and how to avoid devastating impacts in the future."--
