By 2030, experts predict two-thirds of people living on this planet will not have enough water, a situation expected to result in the deaths of millions and an unprecedented rise in military conflicts. Can we as individuals hope to reverse these dire predictions? Award-winning author and water activist Florencia Ramirez believes we can if our conservation efforts focus on the 70 percent of freshwater flowing to the fields and ranches that grow our food. Eat Less Water takes the listener on a journey to meet America's food producers growing food with less water.

In Long Hops, physicist Mark Denny explains, in a clear, conversational style, the science of bird migration - from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights.

Evidence as to Man's Place in Nature was written in 1863 by Thomas Henry Huxley. In this work, Huxley presents evidence for the evolution of man and ape from a common ancestor. Evidence as to Man's Place in Nature was the first book in history devoted to the topic of human evolution, and it discussed this theory in light of anatomical and other evidence.

Jeremy Stone, a renowned, almost Zelig-like figure in the world of public interest activism offers his antic, wry and moving memoirs of a life spent trying to make the world a better place. There probably isn't another human being who's been involved with more issues as an activist than Jeremy Stone. During his tenure as head of the 2,000 member Federation of American Scientists, Stone has been involved with just about every major activist issue of the past quarter century.

This gives a brief and quick overview of evolutionary theories of the origins of early life at the microscopic levels and the view of how organic substances can come from inorganic substances.

This serves as the second book in the Basics of Biology series. In this segment, the functions of membranes are explored. With regards to fully understanding biological organisms, the cell membrane is essential to developing an understanding of how cell function to control the substance that enter and exit them along with they way in which they interact with their environment.

In this book, some of the basic information and background into biology is broken down and explained. This serves as a quick and fast to the point introduction to biology. Some of the concepts explored include cell structure, taxonomy, biochemistry, and systems biology. With listening to this book, one could explain some of the simpler concepts of biology in a short time.

DNA serves as the basic instruction manual for life. In this installment, we look at the way in which DNA is structured, replicated, and how it is packaged into such a small area. This will provide the basic understanding of how genes are structured in an easy to understand way.

The environment can cause - and cure - cancer! Out of the labs of the prestigious Pasteur Institute came decades of research that unlocked the mystery of cancer at the DNA level. But we're only just now finding out about it.

Why do organisms grow old and die? What are the theories of aging? Does the Free Radical Theory of Aging still stack up? How do cells decide when to divide, differentiate or die? What factors accelerate the aging process? This essay takes a look at these issues and would thus be useful to students who want to know more about the processes that control cell death. The essay also documents the more extreme measures that some people have taken in the pursuit of eternal youth.

Emmy Award - winning filmmaker, writer, and naturalist Joe Hutto has done it again. Touching the Wild is the enchanting story about one man who has lived with a herd of mule deer in the Wind River mountains of Wyoming for almost seven years. Why, you may ask, would a person choose to do such a thing? His response: how could you not? For Joe Hutto, close proximity to wild things is irresistible. In Illumination in the Flatwoods he unveiled the secret lives of the wild turkey to great critical acclaim.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

We remember the admonition of our mothers: "Treat others as you want them to treat you." But what if being nice was something we were inclined by nature to do anyway? Renowned neuroscientist Donald Pfaff upends our entire understanding of ethics and social contracts with an intriguing proposition: the Golden Rule is hardwired into the human brain. Pfaff, the researcher who first discovered the connections between specific brain circuits and certain behaviors, contends that the basic ethics governing our everyday lives can be traced directly to brain circuitry.

Twelve renowned scientists and theologians offer penetrating insights into the evolution dialogue in The Deep Structure of Biology. Each considers whether the orthodox model of evolution is sufficient and offers his/her own perspective on evolution and biology. The discussion of biology and evolution in these essays broadens the scope of the traditional evolution discussion as it aims to stimulate the development of further research programs. Scholars in the science and religion field will find this book a valuable resource.

Mark Moffett doesn't just study ants, he travels among them. Moffet holds a Harvard Ph.D. in entomology and is an accomplished scientist, an award-winning author and journalist, and one of the best nature photographers of his generation. Years ago, this free-spirited naturalist left academia behind to plunge into the deepest jungles and observe insect societies up close. Now author Nicholas Griffin takes us inside Moffett's own world, to explore his death-cheating quest for discovery.

Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species.

Human beings have astonishing genetic vulnerabilities. More than half of us will die from complex diseases that trace directly to those vulnerabilities, and the modern world we've created places us at unprecedented risk from them. In It Takes a Genome, Greg Gibson posits a revolutionary new hypothesis: Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren't coping well with modern culture.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

When his missionary brother renounced faith in favor of atheism, Perry Marshall was plunged into crisis and doubt. He decided: “I”m going to let science make this decision for me.” He asked: “Is the hand at the end of my arm purposeful? Or is it purposeless?” He leapt into the void of evolution and the origin of life. He could not have begun to anticipate what he was about to discover. Living things were far more sophisticated than textbooks were saying.
