Estas Crónicas de la extinción relatan la extinción de diversas especies animales. Comienzan con la historia de las tortugas de las islas Galápagos, y continúan en los episodios II y III con el recuento histórico de la manera en que la ciencia comprobó a través del registro fósil la extinción de las especies. La llamada extinción de los dinosaurios se detalla en el episodio IV; mientras que los capítulos V y VI narran las extinciones de la llamada megafauna de la Era de Hielo y la de los parientes extintos del ser humano. En el capítulo VII se abordan las historias de extinción de algunas especies contemporáneas al hombre, y finalmente, en los episodios VIII y IX, se aborda la manera en la que la ciencia enfrenta el problema de las extinciones modernas.

Según J. Miguel Esteban, las nuevas tecnologías del capitalismo cognitivo permiten calcular la magnitud de la sexta extinción y al mismo tiempo impulsar exponencialmente la expansión de los mercados globales del planeta. La extinción antropogénica de la biodiversidad revela también las psicopatologías de un mundo domesticado económica y tecnológicamente en el que se desvanece la necesaria otredad biológica. De modo que, como advertía Heidegger, allá donde mire el hombre no se encuentra más que a sí mismo. Bucles de extinción explora estas y otras psicopatologías sistémicas realimentadas por el cambio climático y la sexta extinción. Esteban se propone así robustecer su propuesta de una educación ambiental experiencial y transdisciplinar, ya defendida en sus últimas publicaciones, con otras aportaciones de las ciencias naturales, sociales y humanas dispuestas a establecer un recorte interdisciplinar y sistémico del ambiente que problematizan, en el que rige la incertidumbre y la exponenciación de las preguntas allí donde apenas hemos empezado a bosquejar respuestas situadas, incompletas, provisionales y sensibles al contexto. El libro Bucles de extinción, del Doctor José Miguel Esteban, ha sido sometido a dictamen por una comisión académica de expertos de la Unión de Científicos Comprometidos con la Sociedad (UCCS), institución de profesionales mexicanos de la ciencia que avala resueltamente la calidad del libro y se enorgullece de que el trabajo importante e innovador de un miembro activo de la UCCS pueda finalmente ser publicado también bajo su sello.

Hemos entrado en la sexta extinción masiva de seres vivos. Es provocada por el abuso sin piedad contra la naturaleza por la acción directa de los humanos.La aniquilación se acelera frente a nuestros ojos y al final será tan trágica como la que causó la desaparición de las especies gigantes. Esta extinción entrará a toda velocidad en la tercera etapa del cambio climático que será cercana al 2100. Cuando termine el proceso del derretimiento de los hielos, y el aumento de la temperatura sobrepase los pronostico anunciados, se producirá mucha nubosidad, una mayor concentración de gas metano, y más CO2, los rayos del sol no penetraran con tanta intensidad y esto traerá una era de hielo que se extenderá miles de años.

The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.

La Tierra comenzó su andadura como planeta hace unos 4500 millones de años. Durante la mayor parte de su evolución, casi el 90% de ese tiempo, consolidó unas condiciones aptas para el desarrollo de los organismos pluricelulares. Sin embargo, para ello tuvo que pasar por diferentes fases evolutivas hasta conseguir unos océanos y una atmósfera con suficiente oxígeno y provista de una capa protectora de ozono que permitiesen el arranque definitivo de la vida. Esta situación se vio drásticamente interrumpida entre los periodos Pérmico y Triásico, hace unos 252 millones de años, cuando una serie de procesos destructivos, encadenados entre sí y originados por un intenso y prolongado vulcanismo originado en la región de la actual Siberia, hizo colapsar los ecosistemas continentales y marinos. El resultado fue una alteración letal de los ecosistemas marinos y continentales que derivó en la mayor extinción masiva conocida, en la que desapareció el 90% de las especies marinas con esqueleto y el 70% de las especies en los continentes.Este libro aborda esta etapa y también la posterior, donde la vida se abrió paso nuevamente en condiciones todavía hostiles para dar la alternativa a nuevos grupos de organismos como dinosaurios, aves, mamíferos y, más tarde, el ser humano. Además, hace una comparación de lo que sucedió entonces con la situación derivada del cambio climático que estamos experimentando en nuestros días.

This is a book about the dramatic periods in the Earth's history called mass extinctions - short periods (by geological standards) when life nearly died out on Earth. The most famous is the mass extinction that happened about 65 million years ago, and that caused the death of the dinosaurs. But that was not the worst mass extinction: that honour goes to the extinction at the end of the Permian Period, about 250 million years ago, when over 90% of life is thought to have becomeextinct.What caused these catastrophes? Was it the effects of a massive meteorite impact? There is evidence for such an impact about 65 million years ago. Or was it a period of massive volcanic activity? There is evidence in the rocks of huge lava flows at periods that match several of the mass extinctions. Was it something to do with climate change and sea level? Or was it a combination of some or all of these?The question has been haunting geologists for a number of years, and it forms one of the most exciting areas of research in geology today. In this book, Tony Hallam, a distinguished geologist and writer, looks at all the different theories and also what the study of mass extinctions might tell us about the future. If climate change is a key factor, we may well, as some scientists have suggested, be in a period of mass extinction of our own making.

In this vast sweep of our Earths history, Michael Benton brings the deep past to life as never before. Deploying the cutting-edge tools in biology, chemistry, physics and geology that are transforming our understanding of previous environmental cataclysms including the incredible new discovery of a hitherto unknown extinction event he uncovers not only their lethal effects but also the processes that brought about such large-scale destruction. Beginning with the oldest extinction, Benton investigates the Late Ordovician, which set the evolution of the first animals on an entirely new course; the late Devonian, brought on by global warming; the cataclysmic End-Permian, which wiped out over 90 per cent of all life on Earth; and, book-ending the age of the dinosaurs, the newly discovered Carnian Pluvial Event and the End-Cretaceous asteroid. He examines how global warming, acid rain, ocean acidification, erupting volcanoes and meteorite impact have affected conditions on Earth, the drastic consequences for global ecology, and how life in turn survived, adapted and evolved. This expert retelling of scientific breakthroughs allows us to link long-ago upheavals to our modern crises. As todays climate scientists and political leaders grapple to understand these processes and our planet enters the sixth great extinction, these insights from the past may hold the key to survival.
