In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

Learn about the nature of Extinction with iMinds insightful knowledge series. Extinction means the death of a species of animal or plant. When you think of extinct species, you probably think of dinosaurs. So it may amaze you to know that 99% of all species that once lived on the earth are now extinct!

A former endangered species biologist looks at the ongoing sixth mass extinction through the prism of human behavior, personal experience, ecology, evolutionary biology, and contemporary conservation efforts. He provides new insights into factors triggering the current mass extinction event and examines conventional wisdom regarding human intelligence. The author suggests—as humanity edges ever closer to disappearing forever—a clear-eyed, real-world rationale for resignation but also acceptance.

Author of At Play in the Fields of the Lord, national Book Award-winner Peter Matthiessen is an accomplished naturalist and one of the most acclaimed writers in the world. This book is a stirring look at the tiger, a magnificent animal that has long fueled human fascination. In critical danger of extinction, only a few thousand of these giant cats remain. Matthiessen's exquisite prose stunningly captures the tigers' dramatic fight to survive.

Bears have always held a central place in our collective memory, from Indigenous folklore and Greek mythology to nineteenth-century fairytales and the modern toy shop. But as humans and bears come into ever-closer contact, our relationship nears a tipping point. Today, most of the eight remaining bear species are threatened with extinction. Some, such as the panda bear and the polar bear, are icons of the natural world; others, such as the spectacled bear and the sloth bear, are far less known.

The great auk is one of the most tragic and documented examples of extinction. A flightless bird that bred primarily on the remote islands of the North Atlantic, the last of its kind were killed in Iceland in 1844. Gisli Pálsson draws on firsthand accounts from the Icelanders who hunted the last great auks to bring to life a bygone age of Victorian scientific exploration while offering vital insights into the extinction of species.

As global rates of plant and animal extinctions mount, anxieties about the future of the earth's ecosystems are fueling ever more ambitious efforts at conservation, which draw on Western scientific principles to manage species and biodiversity. In Revenant Ecologies, Audra Mitchell argues that these responses not only ignore but also magnify powerful forms of structural violence like colonialism, racism, genocide, extractivism, ableism, and heteronormativity, ultimately contributing to the destruction of unique life forms and ecosystems.

A heady blend of international intrigue, social theory, botanical lore, and ecological study, The Cactus Hunters offers complex insight into species extinction, conservation, and more-than-human care.

Insects are dying off at an apocalyptic rate, or are they? Now there's a way to find out. In this limited series, we go to a remote island rainforest to listen to sound-based research that could reveal the truth about global insect death.
