A defense of agroecological, small-scale farming and a robust critique of an industrialized future. As a breakdown of the climate, state power and globalized markets pushes us toward an epochal transition, Chris Smaje offers us a hopeful vision of a relocalized, self-sufficient world.—David Bollier One of the few voices to challenge The Guardian's George Monbiot on the future of food and farming (and the restoration of nature) is academic, farmer and author of A Small Farm Future Chris Smaje. In Saying NO to a Farm-Free Future, Smaje presents his defense of small-scale farming and a robust critique of Monbiot’s vision for an urban and industrialized future. Responding to Monbiot’s portrayal of an urban, high-energy, industrially manufactured food future as the answer to our current crises, and its unchallenged acceptance within the environmental discourse, Smaje was compelled to challenge Monbiot’s evidence and conclusions. At the same time, Smaje presents his powerful counterargument – a low-carbon agrarian localism that puts power in the hands of local communities, not high-tech corporates. In the ongoing fight for our food future, this book will help you to understand the difference between a congenial, ecological living and a dystopian, factory-centered existence.

Pharmaceutical trials are essential to the development of new drugs and treatments, providing the necessary data to ensure they are safe and effective for public use. These trials have evolved over centuries, from rudimentary experiments to the sophisticated, multi-phase studies we see today. They are the cornerstone of modern medicine, influencing the drugs that populate our pharmacies and hospitals. However, the process is not without its flaws, and the history of pharmaceutical trials is marked by ethical concerns, controversy, and a complex relationship between researchers, pharmaceutical companies, and patients. The primary goal of pharmaceutical trials is to test new drugs and therapies on human participants to gather data on their safety, efficacy, and potential side effects. These trials follow a strict protocol, designed to minimize risks while maximizing the quality of the data collected. The process typically begins with preclinical testing in laboratories, followed by clinical trials involving human subjects. These trials are divided into several phases, each designed to answer different scientific questions. From small-scale phase I trials to large-scale phase III studies, the data gathered at each stage is critical in determining whether a drug is ready for approval by regulatory authorities. However, the path from laboratory to pharmacy shelves is not always smooth. The influence of pharmaceutical companies looms large over clinical trials, as they fund many studies and are often the driving force behind research agendas. While their involvement has led to groundbreaking advancements in medicine, it has also raised concerns about conflicts of interest and the integrity of trial data. In some cases, financial pressures have led to the manipulation or suppression of results that could impact a drug’s approval.Ver libro

Uncertain Climes looks to the late nineteenth century to reveal how climate anxiety was a crucial element in the emergence of American modernity. Even people who still refuse to accept the reality of human-induced climate change would have to agree that the topic has become inescapable in the United States in recent decades. But as Joseph Giacomelli shows in Uncertain Climes, this is actually nothing new: as far back as Gilded Age America, climate uncertainty has infused major debates on economic growth and national development. In this ambitious examination of late-nineteenth-century understandings of climate, Giacomelli draws on the work of scientists, foresters, surveyors, and settlers to demonstrate how central the subject was to the emergence of American modernity. Amid constant concerns about volatile weather patterns and the use of natural resources, nineteenth-century Americans developed a multilayered discourse on climate and what it might mean for the nation’s future. Although climate science was still in its nascent stages during the Gilded Age, fears and hopes about climate change animated the overarching political struggles of the time, including expansion into the American West. Giacomelli makes clear that uncertainty was the common theme linking concerns about human-induced climate change with cultural worries about the sustainability of capitalist expansionism in an era remarkably similar to the United States’ unsettled present.Ver libro
"Harnessing Off-Grid Solar Power: Sustainable Solutions for Remote Areas" is a must-read for anyone who wants to use solar energy in areas that are hard to reach or don't have access. This book thoroughly examines how solar power can be used effectively in places where regular grid links aren't possible or aren't available. It goes over the whole process, from evaluating the spot to installing, maintaining, and managing off-grid solar systems for a long time. Readers will learn about the main parts of solar technology, like solar panels, batteries, and inverters, and how to put them together in a way that works in remote areas through detailed descriptions and useful tips. The book talks about the money side of solar projects, including how to analyze costs, make budgets, and determine the return on investment. This helps people make smart choices and get the most out of their investments. "Harnessing Off-Grid Solar Power" is a useful book for people who plan energy use, lead communities, or are interested in finding green energy solutions. It gives people the skills and information they need to use solar power successfully, which helps remote areas move toward cleaner, more reliable energy systems.Ver libro
The concept of the universe has captivated human curiosity for centuries, but what lies at its edge? The truth is that the edge of the universe is not defined by a physical boundary but by the limits of what we can observe and understand. Space stretches endlessly in every direction, but as we look farther and farther, the light from distant objects becomes increasingly redshifted, eventually disappearing beyond our ability to detect it. This phenomenon marks the boundary of the observable universe, a region from which light has had enough time to reach us since the beginning of the universe, around 13.8 billion years ago. At the edge of the observable universe, we find a vast expanse of empty space, known as the "cosmic void." These regions contain few galaxies, stars, or other celestial objects, and their emptiness gives them an eerie and mysterious quality. The voids between galaxies are immense, sometimes stretching hundreds of millions of light-years across, and they represent one of the most puzzling aspects of cosmology. Why are these vast expanses of nothingness so prevalent? And what does it mean for the structure of the universe? As we peer deeper into space, we encounter objects that have been traveling towards us for billions of years, their light providing a glimpse into the past. The most distant galaxies, discovered using advanced telescopes, show us the early universe as it was just a few hundred million years after the Big Bang. These galaxies offer valuable clues about the formation of stars, galaxies, and larger cosmic structures. However, the farther we look, the more difficult it becomes to see clearly. The expansion of the universe means that galaxies are moving away from us at an accelerating rate, causing their light to become increasingly stretched out, or redshifted. This makes them harder to detect and study, and the universe seems to grow darker the farther we look.Ver libro
