Readers will grasp the full picture of this era and how it contributed to American history and culture.
One medium-size whale carcass delivers as much food to the dark, cold ocean depths as 4,000 years of sinking food particles. When a dead whale arrives, the cafe opens for business, and who better than Dan Tavis to show us the bizarre deep-ocean diners who show up? Hagfish, zombie worms, sleeper sharks--this group of patrons is stranger than the denizens of the Mos Eisley Cantina in Star Wars. A fish in a lab coat, piloting a deep-sea submersible, is our guide to the weirdly fascinating goings-on miles beneath the ocean surface. acy.
Decades of commercial whaling nearly decimated a variety of species of this charismatic megafauna. Modern international conventions—starting in the mid-twentieth century—banned most commercial whaling, with the exception of indigenous whale hunting. But Japan, Iceland, and Norway rejected the moratorium and continue to slaughter whales. Science writer Karen Roman Young interviews experts in the field to explore whale biology, habitat, and behaviour. She discusses threats to whale populations, including global warming, commercial shipping and fishing, water pollution and noise pollution. She discusses the technologies of cetacean (whale, dolphin, and porpoise) research, of rescuing stranded, beached, and entangled whales, and whale sanctuaries and other conservation efforts. This deeply researched, well-balanced book offers a broad, thorough, and inspiring look at Earth's largest mammal.
