Lina Zeldovich fished for piranhas in Brazil, cooked a zebu stew in Madagascar, sipped a drink made from a Peruvian viper — and always lived to write the story. She has written for Reader’s Digest, Sierra Club, Audubon, and Scientific American, among others. Her book The Other Dark Matter: The Science and Business of Turning Waste into Wealth and Health will be published by Chicago University Press in 2021.
