Describe al detalle el vulnerable sistema ecológico de la Tierra; ¿Cómo se ha originado, como funciona, cuáles son las zonas más expuestas al deterioro, que puede hacer el hombre y, sobre todo, qué debería dejar de hacer? Útil, ameno e imprescindible.

Des de mitjan dècada del 2000 fins al 2013 Catalunya va viure un procés d’implantació d’energia eòlica que, en molts casos, va despertar l’oposició de part de la població dels territoris implicats pe

¿Podría ser que hubiésemos pensado el socialismo o el feminismo por encima de nuestras posibilidades? ¿Que hubiéramos alentado insostenibles concepciones fosilistas de la emancipación humana? ¿Que la tecnolatría y la hybris contaminasen también nuestras visiones utópicas? En esta era de crisis energética, calentamiento global, Sexta Gran Extinción y crecientes desigualdades, en medio de una crisis civilizatoria que amenaza con convertirse en naufragio, no deberíamos esperar soluciones high-tech y sociedades de alta energía, sino más bien -como mejor posibilidad- comunidades con algo de industria ligera, basadas en tecnologías intermedias. Pero bajo la premisa de una gran descomplejización; y la expectativa de un nivel de vida muy modesto en lo material, en comparación con lo que hoy -de forma nada plausible-sigue prometiendo la ideología dominante. En este libro intentamos pensar nuestra difícil situación en términos de ecosocialismo descalzo. Los retos que plantean estas perspectivas son formidables: comenzando por el reto de hacernos cargo de nuestra situación real, sin fantasías tecnoentusiastas, ilusiones mercadólatras ni autoengaños.

This book is unique in its treatment of biodiversity, which has come to be an emblem of what is worthy of protection and fostering in the natural world. It undertakes a comprehensive, detailed, and careful philosophical analysis of the many reasons that scientists, economists, philosophers, and others offer for why biodiversity is supposed to be such a central good of nature. Its conclusion is both surprising and disturbing: No reason for biodiversity''s good can be found that is not ill-conceived, logically indefensible, internally contradictory, or self-undermining.The profound failure to find the good of nature in its biodiversity is a springboard for rethinking what, exactly, makes the natural world so uniquely and robustly valuable. This leads to a novel suggestion that nature''s value might be located in a particular human-nature relationship, which anchors the appropriate fit of people in the world at large. Understanding nature''s value in this way has far-reaching consequences, which call into question common orthodoxies of conservation, restoration, and environmentalism generally.

This book constitutes a key reference on the use of algae in the biopharmaceuticals production field; providing an updated outlook on the achievements accomplished thus far and transmitting a prospective view for this biotechnological application. This book provides a detailed description of the technology as well as an updated outlook of the strides achieved thus far in the field of algae-based biopharmaceuticals. Algae constitute attractive expression hosts for the production of recombinant proteins with medical applications. Among the features that make them attractive candidates are: low cost, fast growth, wide biosynthetic capacity, and absence of human pathogens; which constitute substantial advantages with respect to bacterial and mammalian systems. First, the features of algae as convenient hosts for the production of BFs are analyzed in terms of production costs, biosynthetic capacity, and safety (Chapter 1). Second, the genetic engineering tools for algae-species are described. Nuclear and chloroplast-based expression approaches are analyzed and compared in terms of biosynthetic advantages, gene expression complexity, and DNA transfer approaches (Chapter 2). In the following sections, chapters 3 to 7, the state of the art on producing distinct types of BFs in algae species is presented. Although this book is mainly focused on BFs, considering that the production of compounds with health-promoting properties are achieved using genetically-engineered algae strains, chapter 8 deals with nutraceuticals. In the ninth chapter, the developments reported thus far are placed in perspective and challenges for the field are discussed. Critical future prospects comprise the following: optimizing large-scale production in bioreactors, implementing glycoengineering approaches, optimizing nuclear expression, exploring new approaches for oral delivery, and implementing regulatory frameworks to accomplish technology transfer and regulatory approval of algae-made BFs.

The genetic improvement of fish for aquaculture and related fisheries is a field of research that has seen immense advances in recent years. Yet there has been no book which provides an accessible overview of the subject until now. The book fills this gap in the literature. The contents include polyploidy, sex-reversal and breeding, gene mapping and commercial applications.
