Showing results for "Extinction" in Ecology

We live in an age of mass extinction. The earth's biodiversity is decreasing at a faster rate than ever. Industrial agriculture and the standardisation of taste are not only wiping out many edible plants but also the food cultures, histories and livelihoods that go with them. Inspired by a global project to collect and preserve foods that are at risk of extinction, Dan Saladino sets out to encounter these endangered foods.

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.

Many scientists believe that we are currently living through the Earth’s sixth mass extinction, with species disappearing at a rate not seen for tens of millions of years – a trend that will only accelerate as climate change and other pressures intensify. What does it mean to live in such a time? And what exactly do we lose when a species goes extinct? In Lost Wonders conservationist and science writer Tom Lathan tells the stories of ten species that have lived, died out and been declared extinct since the turn of the twenty-first century.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

We are in the midst of an extinction event: the sixth mass extinction on Earth and one entirely caused by mankind. All species become extinct sooner or later, but we have accelerated that natural process several hundredfold, and now, it is happening right in front of our eyes. Extinction has a terrifying finality to it. And many species have already been lost to us forever; there is little we can do about that. What we can do, however, is reflect, remember, and ultimately acknowledge the unvarnished truth.

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.

Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender's Blue? Or the St. Francis' Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures - some numbering no more than what can be held in one hand.

If you're a person who wants to know the secrets of humankind, nature, and evolution, then you're about to discover how to increase sensitivity to the problems of our planet right now! If you're serious about increase sensitivity to the problems of our planet and you really want to know the answers to these great life's questions, then you need to get a copy of A World without Humans: Pros & Cons of Our Eventual Extinction right now.

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.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

Extinción nos revela con evidencia científica la crisis ecológica y climática que atraviesa nuestro planeta. En los próximos cincuenta años 4000 millones de personas vivirán en zonas no aptas para la producción de alimentos. Para 2080 América del Sur estará en una sequía extrema. El 60% de los mamíferos y el 70% de las aves son criados para alimentar humanos.
