Carl Safina is the author of, most recently, Beyond Words: What Animals Think and Feel. I consumed it on Audible a couple of years ago, and was utterly mesmerized and transformed by the listening. I think it was one of the sneaky factors that pushed me, somewhat against my better judgment, into the Animal Welfare camp of the plant-based movement. The book describes the author's encounters with three fascinating and endangered animal populations - the elephants of East Africa, the wolves of Yellowstone, and the Orcas of the Pacific Northwest - and the humans who have devoted their lives to studying, documenting, and understanding these magnificent creatures.
