When we use chemical fertilizers, we injure the microbial life that sustains plants and then become increasingly dependent on an arsenal of toxic substances. Teaming with Microbes offers an alternative to this vicious circle and details how to garden in a way that strengthens, rather than destroys, the soil food web. You’ll discover that healthy soil is teeming with life - not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms.

Most gardeners realize that plants need to be fed but know little to nothing about the nature of the nutrients involved or how they get into plants. Teaming with Nutrients explains how nutrients move into plants and what both macro-nutrients and micro-nutrients do once inside. It shows organic gardeners how to provide these essentials.

A former endangered species biologist looks at the ongoing sixth mass extinction through the prism of human behavior, personal experience, ecology, evolutionary biology, and contemporary conservation efforts. He provides new insights into factors triggering the current mass extinction event and examines conventional wisdom regarding human intelligence. The author suggests—as humanity edges ever closer to disappearing forever—a clear-eyed, real-world rationale for resignation but also acceptance.

The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs' clinic to the present.

Join us on a journey through how we understand the universe, from its most basic particles and forces to planets, stars, and galaxies, and back through cosmic history to the birth of the cosmos. Conflicting notions about our place in the universe are defined, defended, and critiqued from scientific, philosophical, and religious viewpoints. The authors' engaging and witty style addresses what fine tuning might mean for the future of physics and the search for the ultimate laws of nature.
