Synopsis
Si en sus anteriores libros Richard Leakey y Roger Lewin ofrecían un profundo análisis del pasado de la vida y de los comienzos de la humanidad, en La sexta extinción vuelven su mirada, no sin preocupación, hacia el futuro de la vida, un futuro no tan lejano y que presagia un final. A lo largo de la historia de la vida en la Tierra han tenido lugar cinco grandes extinciones , la más reciente hace 65 millones de años, cuando los dinosaurios perecieron en un brevísimo lapso de tiempo. Cada una de estas extinciones fue catastrófica : en todas ellas desapareció al menos el 65 por ciento de las especies vivientes. No obstante, si bien la causa de esas extinciones es aún materia de controversia ―¿repentinos cambios climáticos, asteroides, dificultades de evolución ?―, no ocurre así con las consecuencias y las características de estas catástrofes, que parecen seguir todas un mismo modelo. Aportando pruebas científicas irrefutables, Leakey y Lewin demuestran que la sexta extinción ha empezado ya : cada año, el hombre barre de la faz de la Tierra a trescientas especies vivas. Y esta extinción amenaza al planeta entero, incluida la especie Homo sapiens … Si no empezamos a tomar conciencia de las consecuencias devastadoras de nuestra conducta rapaz y aniquiladora, irremisiblemente la especie humana caerá (tras el mastodonte, el alca gigante, la paloma migradora y sus demás víctimas) en el olvido de la extinción.

Paperback. Condition: Very Good. Over the last 530 million years there have been five mass extinctions of species-the last,65 million years ago,when the dinosaurs disappeared.The biodiversity of our planet may now be on the verge,Leakey and Lewin believe,of a sixth extinction,caused this time by the relentless expansion and limitless appetites of human beings. The new science of 'biodiversity',presented clearly and cogently by Leakey and Lewin,combines insights from palaeontology,biology,ecology and even economics.It integrates the role of Darwenian evolution with the increasingly recognised importance of external and unpredictable forces. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged. Seller Inventory # GOR001175412
