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.

In Extinction and the Human, Timothy Sweet ponders the realities of animal extinction and endangerment and the often divergent Native American and Euro-American narratives that surround them. He focuses especially on the force of human impact on megafauna—mammoths, whales, and the North American bison. Ultimately, he argues, it is the critical assessment of ideas of human exceptionalism that provides a necessary counterpoint both to apologies for human mastery over nature and deep ecology's attempts to erase the human.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

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.

Mass Extinction Number 6: The End of Our Time on Earth is a sobering and powerful exploration of the ongoing ecological collapse unfolding in the 21st century—a catastrophe not caused by an asteroid or supervolcano, but by us. In the tradition of Rachel Carson’s Silent Spring and Elizabeth Kolbert’s The Sixth Extinction, Ronald Baldwin brings a unique blend of investigative clarity, emotional urgency, and narrative power to this stark warning about humanity’s role in triggering the sixth mass extinction event in Earth’s history.

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.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

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.

Earth is embroiled in its sixth major extinction event—this time caused not by asteroids or volcanos, but by us. At bottom, preventing this sixth extinction is a spiritual and philosophical problem, for it is the assumptions defining us and our relation to earth that are driving the devastation. Those assumptions insist on a fundamental separation of human and earth that devalues earth and enables our exploitative relation to it.

As wildfires char the American West, extreme weather transforms landscapes, glaciers retreat, and climate zones shift, we are undeniably experiencing the effects of the climate crisis in more and more destructive ways. Climate change is impacting every inhabited region of the world, but there is much we can still do. Unsettling explores human impacts on the environment through science, popular culture, personal narrative, and landscape. Science writer Elizabeth Weinberg explores how climate change is a direct result of white supremacy, colonialism, sexism, and heteronormativity.

When we humans love foods, we love them a lot. In fact, we have often eaten them into extinction, whether it is the megafauna of the Paleolithic world or the passenger pigeon of the last century. In Lost Feast, food expert Lenore Newman sets out to look at the history of the foods we have loved to death and what that means for the culinary paths we choose for the future.

In Unnatural Companions, journalist Peter Christie issues a call to action for pet owners. If we hope to reverse the alarming trend of wildlife decline, pet owners must acknowledge the pets-versus-conservation dilemma and concede that our well-fed and sheltered cats too often prey on small backyard wildlife and seemingly harmless reptiles released into the wild might be the next destructive invasive species. We want our pets to eat nutritionally healthy food, but how does the designer food we feed them impact the environment?

Extinction Rebellion are inspiring a whole generation to take action on climate breakdown. Now you can become part of the movement - and together, we can make history. It's time. This is our last chance to do anything about the global climate and ecological emergency. Our last chance to save the world as we know it. Now or never, we need to be radical. We need to rise up. And we need to rebel.

Join author Denver Michaels as he delves into folklore and eyewitness accounts to learn the truth about these extinction escapees.

If you could bring back one living being from the whole of the history of time, what would you choose? Comedian and former stem-cell biologist Helen Pilcher has thought about this problem - a lot. In Bring Back the King, Helen explains the cutting-edge science that makes the resurrection of extinct animals a very real possibility and highlights her choices from eras gone by, from the king of the dinosaurs, Tyrannosaurus rex, to the King of Rock 'n' Roll, Elvis Presley.

In the early 19th century passenger pigeons accounted for 25 to 40 percent of North America’s birds, traveling in flocks so massive as to block out the sun for hours. Although adults weighed only twelve ounces, they nested and roosted in the millions, destroying large oaks as if hit by hurricanes. Their favorite foods were the seeds and nuts of beech, chestnuts, and other forest trees, but they also raided farmers’ buckwheat, wheat, corn, and rye crops.
