En los últimos años comienzan a escucharse voces, y en 2017 de una forma especial, que nos hablan de que se está apreciando una tendencia en los incendios forestales hacia situaciones cada vez más graves e incontrolables. Se cita al cambio climatico, a un urbanismo desarticulado creciente, a la falta de medidas de prevencionA estas y a otras cuestiones trata de aportar respuestas este libro, que se abre con una descripcion historica del uso (y abuso) del fuego en Galicia hasta la situacion que vivimos en la actualidad, que se inicia con la desarticulacion del sistema agro forestal en torno a los años sesenta del pasado siglo. A esta problematica socioeconomica se le dedican los dos capitulos siguientes. A continuacion, se tratan las alternativas que intentan afrontar el futuro y las medidas de lucha y prevencion, asi como los daños a bienes y personas. Los dos ultimos capitulos se refieren a la educacion y a la responsabilidad social de los gallegos, aspectos singulares y decisivos en la lucha contra el fuego.Este libro se escribio bajo la impresion de las imagenes todavia vivas de unas llamas que caminaban con una velocidad inusitada desde la frontera portuguesa hasta Terra de Montes, de unas pavesas que volaban y prendian en espacios ineditos de la ciudad de Vigo o de unos fuegos que con demoledora persistencia arrasaban las cumbres de las sierras ourensanas. Pero tambien con la responsabilidad de los muchos años que la mayoria de los autores de este libro llevan ocupandose del problema de los incendios forestales en Galicia. Son diferentes miradas expertas, estimuladas por las emociones de este desgraciado año 2017, redactadas bajo la urgencia del momento, pero tambien atemperadas y contrastadas por las muchas experiencias y reflexiones a que dieron lugar todos los fuegos que fueron asolando Galicia en esta ultima y larga etapa incendiaria de su historia.

What can we really do about the climate emergency The inconvenient truth is that we are causing the climate crisis with our carbon intensive lifestyles and that fixing or even just slowing it will affect all of us But it can be done In Net Zero economist Dieter Helm addresses the action we all need to take to tackle the climate emergency personal local national and global Reducing our own carbon consumption is the first step Helm argues that we the ultimate polluters should pay based on how much carbon the products we buy produce We need a carbon price and one that applies to everything and everywhere from flights to food and farming The goal of net zero carbon emissions needs a rethink and this book sets out how to do it in a plan that could and would work Do this and we make no further contribution to global warming in a way that embraces sustainable economic growth and does not harm other aspects of the environment in the process There is a solution and we must find it Everything is at stake

For all the selfishness of genes they team up to survive Is the history of life in fact a story of cooperation Amid the violence and brutality that dominates the news it s hard to think of ourselves as team players But cooperation Jonathan Silvertown argues is a fundamental part of our make up and deeply woven into the whole four billion year history of life Starting with human society Silvertown digs deeper to show how cooperation is key to the cells forming our organs to symbiosis between organisms to genes that band together to the dawn of life itself Cooperation has enabled life to thrive and become complex Without it life would never have begun

The incredible story of Joep Lange s life and his unrelenting quest to end the HIV epidemic When Malaysia Airlines flight MH17 was shot down by pro Russian rebels in July 2014 the world wondered if a cure for HIV had fallen from the sky and disappeared among the burning debris Seated in the plane s business class cabin was Joseph Lange better known as Joep a shrewd Dutch doctor who had revolutionized the world of HIV and AIDS and was working on a cure Dr Lange graduated from medical school in 1981 right as a new plague swept across the globe His story became intertwined with the story of HIV At once a physician scientist AIDS activist and medical diplomat Lange studied ways to battle HIV and prevent its spread from mother to child Fighting the injustices of poverty Lange advocated for better access to health care for the poor and the vulnerable He championed the drug cocktail that finally helped rein in the disease and was a vocal proponent of prophylactic treatment for those most at risk of contracting HIV The Impatient Dr Lange is the story of one man s struggle against a global pandemic and the tragic attack that may have slowed down the search for a cure Seema Yasmin charts the course of the HIV epidemic and Dr Lange s career as a young doctor

This lucid and entertaining book presents compelling scientific evidence that proves what many of us have perhaps long suspected nature is really good for us I found it revelatory Richard Deverell Director of Kew A revolutionary science based look at the ways nature can help make us healthier Fifteen years ago University of Oxford Professor Kathy Willis read a study that radically changed her view of our relationship to the natural world The study revealed that hospital patients recovering from surgery improved three times faster when they looked out of their windows at trees rather than seeing walls Since then she has dedicated her research to proving this link between the amount of green space in our lives and our better health mood and longevity For the first time ever Good Nature brings together these recent scientific findings and shares the simple changes we can all make in our lives The book is full of surprising and practical ways that nature can improve our lives such as did you know that cedar enhances cancer fighting cells in our immune system Or that touching wood makes us feel calmer the woodier the knot ier the better Or that the scent of roses helps people drive more calmly and safely Even having a pot plant by your desk can make a
