On the Origin of Species by Charles DarwinDarwins groundbreaking work introduces the theory of evolution by natural selection. It explains how species adapt and evolve over time, fundamentally altering the scientific understanding of biodiversity, heredity, and the interconnectedness of life on Earth.

This work is a philosophical investigation into the argumentative conditions for intercultural dialogue in Latin America. Through a critical discussion of some key theories of argumentation and intercultural dialogue and a thoughtful analysis of the Latin-American context of diversity, this book develops an intercultural model of argumentation based on the criteria of Intercultural Reasonableness and Discursive Interpellation. These criteria, which have a contextual and dialogical character, aim to offer the appropriate normative ground for a polylogical argumentative dialogue, in which the parties can make use of their own types of language and rationality without presupposing a common standard for the rational evaluation of arguments.

Inspired by the life and times of Alexander von Humboldt, 1769-1859 , this biography follows Humboldt, who is considered the father of the Natural Sciences and in his day was as well known as Napoleon, and traces his childhood in what was then Prussia, his education at various Universities his training as a mining engineer and how he progressed into the sciences. Duringing the Age of Enlightenment, Humboldts journey to South America between 1799 and 1804 with Aime Bonpland, changed the course of both their lives and during this period of exploration, they sent back to Paris and Berlin some 6000 samples of new species, minerals and animals. En route the scientists collected a mass of detailed information - cartographical, geological, astronomical, botanical, anthropological and linguistic - that took a life time to decipher.

Technology is not neutral.From the plow to the printing press, technology has always shaped human life and informed our understanding of what it means to be human. And advances in modern technology, from computers to smartphones, have yielded tremendous benefits. But do these developments actually encourage human flourishing?Craig Gay raises concerns about the theological implications of modern technologies and of philosophical movements such as transhumanism. In response, he turns to a classical affirmation of the Christian faith: Jesus Christ, the eternal Word of God, took on human flesh. By exploring the doctrine of the incarnation and what it means for our embodiment, Gay offers a course correction to the path of modern technology without asking us to unplug completely.Gay demonstrates that the doctrine of the incarnation is not neutral either. It presents an alternative vision for the future of humanity.

A Crisis Like No Other: Understanding and Defeating Global Warming couples engaging and creative storytelling with accurate details to explain global warming. It covers both the technical and human issues of global warming by addressing whats causing global warming, and why people dont believe it exists. The book tells readers how to convince others that global warming is not only real, but life-threatening, and offers a clearly laid out path to solve it. The book is accurate and carefully researched, drawing on the authors thirty years studying the science of global warming, and the human psyche that surrounds it. The author breaks down the subject into four parts, which can be thought of as four mini-books in one. The first part covers the psychology of global warming denial, how to defend ourselves against its lies and fake news, and how to convince others of global warmings grave harm. The second part describes exactly what global warming is. The third answers the question what makes us so sure? Finally, the last part provides a road map showing us how to defeat global warming. This book is comprehensive, fast paced, and easily accessible to readers from all walks of life. It provides an overview of everything one needs to know about global warming and, as such, is an excellent survey of global warming topics. In addition to being an easy and enjoyable read for the general public, A Crisis Like No Other: Understanding and Defeating Global Warming serves as a handy primer on climate change for environmental science classes.

We have lived in a world that had, until the arrival in 2020 of the coronavirus Covid-19, not suffered a serious pandemic for a century, and society had almost forgotten the enormous impact created by highly infectious diseases. Infectious diseases, however, played major roles in ending the Golden Age of Athens, wrecked Justinians plans to restore the Roman Empire to its former glory, and killed untold millions in Latin America after the Spanish invasion. Armies of Pestilence explores the impact of these diseases on history. Despite their importance, historians have tended to minimise the role of infectious disease - partly because of a lack of scientific knowledge, and this has resulted in a distorted view both of the past and of the danger of disease to modern society. In Armies of Pestilence, R.S. Bray, a distinguished biologist who here shows himself also to be an able historian, corrects this view. The book surveys the principal epidemics around the world and across the centuries, in each case discussing the origins of the outbreaks, the symptoms, the mortality rate and the social and economic effect. Where particular diseases cannot be identified with certainty the best scholarly opinions are discussed. Bray pays special attention to the infamous Yersina pestis, the organism that caused the Black Death. Other diseases discussed include malaria, smallpox, typhus, cholera and influenza, and AIDS. One of the themes of the book is the relationship between disease and war, with the former often causing more deaths than the latter, as was the case with the great influenza pandemic of 1918-19, at the end of the First World War. The inability of governments to deal effectively with disease is also made clear.

Pollution of the aquatic environment is a real threat across the globe. It is becoming a topic of intense study for researchers. It has been updated and almost completely revised. The Mediterranean Sea has been recognized as a target hotspot of the world as the pollutant concentration in this region is greater than the levels in other oceans. The book summarizes research on marine pollutants in the Mediterranean Sea. It presents 5 concise reviews focusing on microplastics, rare earth elements and biotoxins which are now commonly found in the region. The Editors also emphasize on pollution problems in the Mediterranean region, with 2 chapters presenting studies on Lebanon and Morocco, respectively. The book adds to the collective information on Mediterranean marine pollution. Additionally, references are included at the end of each chapter for the benefit of advanced readers. The contributions also include discussions on important techniques used to monitor and control marine pollution, such as the bio-monitoring of effluents, and ecological impact assessment of microplastic pollution on fish and the environment. Audience Students and researchers in environmental science programs; policymakers in Mediterranean environmental agencies.
