Carbon is arguably humankind's most important chemical element - indeed, possibly the most important element in the universe. Created in the fiery furnaces of stars, carbon is the chemical backbone of the planets and life as we know it. It is essential to every part of our lives: the bones and tissue which give us all shape, the food we eat, the tools we use, the climate which supports life on this planet. Despite these facts, carbon's importance is often overlooked. In this short, popular-level book, astronomers Theodore Snow and Donald Brownlee consider carbon from a cosmic perspective, explaining the inherent chemical and physical nature of the element as well as the ways in which it is foundational to nearly everything in the universe, our environment, and our lives. Snow and Brownlee first discuss the carbon's discovery and origin, as well as the aspects of carbon's chemical makeup (such as its incredible ability to link to itself and bond with many other elements) that make it so special and important to the history of the universe and our solar system. After addressing carbon's role in the chemical evolution of the universe, including the formation and evolution of galaxies, stars, planets, and life, the authors go on to describe its technological uses and its influence on Earth's climate and planetary habitability more generally. Throughout, the authors discuss not only the element itself, but also the scientists across numerous disciplines whose research helped illuminate carbon's wide-ranging importance"--
Describes some of the bad changes man is inflicting on the world, such as the cutting down of tropical forests, the destroying of ozone, oil spills, and acid rain.
A Book-Lover's Holidays in the Open is a classic adventure text by Theodore Roosevelt that tells of the authors outdoor adventures in North and South America, and it contains the following excerpt: The man should have youth and strength who seeks adventure in the wide, waste spaces of the earth, in the marshes, and among the vast mountain masses, in the northern forests, amid the steaming jungles of the tropics, or on the deserts of sand or of snow. He must long greatly for the lonely winds that blow across the wilderness, and for sunrise and sunset over the rim of the empty world. His heart must thrill for the saddle and not for the hearthstone. He must be helmsman and chief, the cragsman, the rifleman, the boat steerer. He must be the wielder of axe and of paddle, the rider of fiery horses, the master of the craft that leaps through white water. His eye must be true and quick, his hand steady and strong. His heart must never fail nor his head grow bewildered, whether he face brute and human foes, or the frowning strength of hostile nature, or the awful fear that grips those who are lost in trackless lands. Wearing toil and hardship shall be his; thirst and famine he shall face, and burning fever. Death shall come to greet him with poison-fang or poison-arrow, in shape of charging beast or of scaly things that lurk in lake and river; it shall lie in wait for him among untrodden forests, in the swirl of wild waters, and in the blast of snow blizzard or thunder-shattered hurricane. Theodore Roosevelt
