Personal, anecdotal, and highly engaging, "Watching Giants" opens a window on a world that seems quite like our own, yet is so different that understanding it pushes the very limits of our senses. Elin Kelsey's colorful first-person account, drawing from her rich, often humorous, everyday experiences as a mother, a woman, and a scientist, takes us to the incredibly productive waters of the Gulf of California and beyond, to oceans around the world. Kelsey brings us along as she talks to leading cetacean researchers and marine ecologists about their intriguing discoveries. We encounter humpback whales that build nets from bubbles, gain a disturbing maternal perspective on the dolphin-tuna issue, uncover intimate details about whale sex, and contemplate the meaning of the complex social networks that exist in the seas. What emerges alongside these fascinating snapshots of whale culture is a dizzying sense of the tremendous speed with which we are changing the oceans' ecosystems - through overfishing, noise pollution, even real estate development. "Watching Giants" introduces a world of immense interconnectivity and beauty - one that is now facing imminent peril.
