Here's a sobering look at the human race's impact on its environment, from the authors of Origins (1977) and Origins Reconsidered (1992). In addition to his work in unearthing the remains of early hominids, Leakey spent five years as director of Kenya's Wildlife Services, fighting the spread of elephant poaching. Many of his insights in this book arise from the recognition that our species now has the power to bring about the extinction of a majority of our fellow inhabitants of the planet. Of course, mass extinctions are not rare in the fossil record; there have been at least five occasions when nearly two-thirds of living species disappeared from the face of the earth. Most were killed off by natural disasters, whether on the scale of the meteor impact believed to have ended the age of dinosaurs or an isolated habitat being destroyed by a change in local climate. But beginning with the late Pleistocene, the impact of human beings becomes evident. The extinction of large mammalsincluding mammoths, mastodons, giant ground slothsin North America just over 10,000 years ago was almost certainly due to hunting by the newly arrived ancestors of today's Native Americans. Now the encroachment of human activities on the tropical rain forests (where a vast majority of living species reside) threatens to escalate the death toll to a level comparable to the five great prehistoric extinctions. The authors urge us to take action to prevent this catastrophe and present strong evidence that we are far richer leaving the forests undeveloped than we can ever be by letting them fall prey to monoculture and corporate use. Eloquently argued and rigorously supported by scientific evidence, this is a powerful document in the fight to preserve our natural heritage while there is still time.

An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both...
Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.

BOOK REVIEW
Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...
Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.
As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”
Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.Pub Date: May 6, 2003
