A couple working six months per year for 50 hours per week on 20 acres can net $25,000 to $30,000 per year with an investment equivalent to the price of one new medium-sized tractor. Seldom has agriculture held out such a plum. In a day when mainline farm experts predict the continued demise of the family farm, the pastured poultry opportunity shines like a beacon in the night, guiding the way to a brighter future.

In the final decades of the 19th century, three brilliant and visionary titans of America's Gilded Age - Thomas Edison, Nikola Tesla, and George Westinghouse - battled as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires.

Discover magazine recently called Richard Dawkins "Darwin's Rottweiler" for his fierce and effective defense of evolution. Prospect magazine voted him among the top three public intellectuals in the world (along with Umberto Eco and Noam Chomsky).

A renal diet is concerned with regulating the intake of protein and phosphorus in your diet. Limiting your sodium intake is also important. By controlling these two factors, you can control the majority of the toxins/waste produced by your body, which will help your kidney function. If you catch it early enough and modify your diet with great caution, you may be able to avoid complete renal failure. If you catch this early, you can eliminate the issue.

Carbon is the only element that animates the entirety of the living world. Though comprising a tiny fraction of Earth’s composition, our planet is lifeless without it. Yet it is maligned as the driver of climate change, scorned as an errant element blamed for the possible demise of civilization. Here, Paul Hawken looks at the flow of life through the lens of carbon. Embracing a panoramic view of carbon’s omnipresence, he explores how this ubiquitous and essential element extends into every aperture of existence and shapes the entire fabric of life.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

Everything All at Once is an exciting, inspiring call to unleash the power of the nerd mindset that exists within us all. Nye believes we'll never be able to tackle our society's biggest, most complex problems if we don't even know how to solve the small ones. Step by step, he shows his listeners the key tools behind his everything-all-at-once approach: radical curiosity, a deep desire for a better future, and a willingness to take the actions needed to make it a reality.

If there is one belief that has united the left and the right, psychologists and philosophers, ancient thinkers and modern ones, it is the tacit assumption that humans are bad. It's a notion that drives newspaper headlines and guides the laws that shape our lives. From Machiavelli to Hobbes, Freud to Pinker, the roots of this belief have sunk deep into Western thought. Human beings, we're taught, are by nature selfish and governed primarily by self-interest.

Sand, salt, iron, copper, oil, and lithium. These fundamental materials have created empires, razed civilizations, and fed our ingenuity and greed for thousands of years. Without them, our modern world would not exist, and the battle to control them will determine our future. In Material World, Ed Conway embarks on an epic journey across continents, cultures, and epochs to reveal the underpinnings of modern life on Earth—traveling from the sweltering depths of the deepest mine in Europe to spotless silicon chip factories in Taiwan to the eerie green pools where lithium originates.

This book exposes the truth that the climate change hoax is a political movement aimed at eliminating capitalism by spreading alarming disinformation that in order to "save the Earth" from global warming, we must reduce carbon dioxide emissions by switching from hydrocarbon fuels to renewable energies. The Truth About Energy, Global Warming, and Climate Change: Exposing Climate Lies in an Age of Disinformation reveals a science-based understanding of Earth's climate and temperature that Green New Deal proponents are trying to hide.

We have never had to feed as many people as we do today. And yet, we misunderstand the essentials of where our food really comes from, how our dietary requirements shape us, and why this impacts our planet in drastic ways. As a result, in our economic, political, and everyday choices, we take for granted and fail to prioritize the thing that makes all our lives possible: food. In this ambitious, myth-busting book, Smil investigates many of the burning questions facing the world today.

John Ratey, best-selling author and clinical professor of psychiatry at Harvard Medical School, lucidly explains the human brain's workings, and paves the way for a better understanding of how the brain affects who we are. Ratey provides insight into the basic structure and chemistry of the brain, and demonstrates how its systems shape our perceptions, emotions, and behavior. By giving us a greater understanding of how the brain responds to the guidance of its user, he provides us with knowledge that can enable us to improve our lives.

At various times in a span of fifteen years, John McPhee made geological field surveys in the company of Eldridge Moores, a tectonicist at the University of California at Davis. The result of these trips is Assembling California, a cross-section in human and geologic time, from Donner Pass in the Sierra Nevada through the golden foothills of the Mother Lode and across the Great Central Valley to the wine country of the Coast Ranges, the rock of San Francisco, and the San Andreas family of faults.

The commercial driver industry is fast-growing yet continuously faced with a shortage of certified CDL drivers. Certification starts with passing the CDL written exam and that's where many fall short. We aim to change that trend. We also aim to enhance the learning experience of new commercial drivers and improve their driving capabilities.

Humanity is on the precipice of a great climate migration, and Americans will not be spared. Tens of millions of people are likely to be driven from the places they call home. Poorer communities will be left behind, while growth will surge in the cities and regions most attractive to climate refugees. America will be changed utterly.

Birds. Over 9,000 species, the most widespread of all animals: on icebergs, in the Sahara or under the sea, at home in our gardens or flying for over a year at a time. Earthbound, we can only look and listen, enjoying their lightness, freedom and richness of plumage and song. David Attenborough has been watching and learning all his life. His classic book, now fully updated with the latest discoveries in ornithology, is a brilliant introduction to bird behaviours around the world: what they do and why they do it.
