Una crisis colectiva requiere una acción colectiva. Ahora más que nunca, la gente está uniéndose en solidaridad y participando en la desobediencia civil para exigir un futuro seguro y sostenible. No importa si eres un activista con experiencia o si es tu primera protesta. Considera este libro tu caja de herramientas. Aqui tienes una guia personal y practica a la crisis climatica, completa con lecciones de la mano de expertos en los temas mas urgentes de esta lucha: el Green New Deal, el daño irreparable que se esta causando en nuestros oceanos y bosques; un acceso cada vez menor al agua limpia y segura y de que maneras se entrelazan el cambio climatico, la guerra, el ejercito, la migracion y los derechos humanos. Cada capitulo te dotara de la informacion que necesitas y te ofrecera medidas concretas y directas que tu y tu comunidad podreis poner en practica de inmediato. JUNTOS SOMOS MAS FUERTES QUE POR SEPARADO.ESTA ES TU LLAMADA A LA ACCION. ¡UNETE!

Los números son escalofriantes. En una sola generación hemos investigado las partículas elementales, reinterpretado el universo, explorado el sistema solar, cuatriplicado la población y destruido más superficie del mundo que en toda la historia humana. ¿Como hemos podido llegar en tan poco tiempo a agotar todos los recursos naturales de la Tierra y a convertir su clima en una amenaza para nuestra propia supervivencia? Una pregunta incomoda para la mayoria de nosotros que considera el dominio sobre el planeta una consecuencia logica y natural de nuestra inteligencia, cuando no un derecho divino otorga-do en nuestra creacion. El autor nos invita a inaugurar una nueva forma de ver el mundo y a nosotros mismos para responder a esta pregunta. Un viaje tan apasionante como imprescindible para estar a la altura del momento historico en el que vivimos y encontrar alternativas a nuestra actual forma de vida.

Invasive species come in all sizes, from plant pathogens like the chestnut blight in eastern North America, to the red imported fire ant that has spread throughout the South, the predatory Indian mongoose now found in the Caribbean and Hawaii, and the huge Burmese python populating the Florida swamps. And while many invasive species are safe and even beneficial, the more harmful varieties cost the world economy billions of dollars annually, devastate agriculture, spread painful and even lethal diseases, and otherwise diminish our quality of life in myriad surprising ways. In Invasive Species: What Everyone Needs to Know, award-winning biologist Daniel Simberloff offers a wide-ranging and informative survey that sheds light on virtually every aspect of these biological invaders. Filled with case studies of an astonishing array of invasive species, the book covers such topics as how humans introduce these species-sometimes inadvertently, but often deliberately-the areas that have suffered the most biological invasions, the methods we use to keep our borders safe, the policies we currently have in place to manage these species, and future prospects for controlling their spread. An eminent ecologist, Simberloff analyzes the direct and indirect impacts of invasive species on various ecosystems, such as when non-native species out-compete native species for food or light, describes how invasive species (such as the Asian mosquito that is a vector for West Nile virus, itself an invasive species) transmit pathogens, and explains his acclaimed theory of "invasional meltdown" in which two or more introduced species combine to produce a far more devastating impact than any one of them would have caused alone. The book also discusses the more controversial issues surrounding invasive species and it concludes with suggested readings and a list of related web sites.

This pioneering encyclopedia illuminates a topic at the forefront of global ecologybiological invasions, or organisms that come to live in the wrong place. Written by leading scientists from around the world, Encyclopedia of Biological Invasions addresses all aspects of this subject at a global levelincluding invasions by animals, plants, fungi, and bacteriain succinct, alphabetically arranged articles. Scientifically uncompromising, yet clearly written and free of jargon, the volume encompasses fields of study including biology, demography, geography, ecology, evolution, sociology, and natural history. Featuring many cross-references, suggestions for further reading, illustrations, an appendix of the worlds worst 100 invasive species, a glossary, and more, this is an essential reference for anyone who needs up-to-date information on this important topic.Encyclopedia of Biological Invasions features articles on: Well-known invasive species such the zebra mussel, chestnut blight, cheatgrass, gypsy moth, Nile perch, giant African snail, and Norway rat Regions with especially large numbers of introduced species including the Great Lakes, Mediterranean Sea, Hawaiian Islands, Australia, and New Zealand.
