Yvonne Baskin, a science writer, takes us on an intriguing tour of the planet’s soils and sediments. Did you know, for example, that because earthworms aren’t native to much of North America, fishermen should dump leftover bait in the trash rather than on the ground? Baskin also helps sort out age-old arguments, such as whether grazing is good for soil and plant life (short answer: depends on the land being grazed).
