A woman whose pioneering work in the 1970s still makes front-page news, Donella Meadows was a scientist, author, teacher, and farmer widely considered ahead of her time. She was one of the world’s foremost systems analysts and lead author of the influential Limits to Growth–the 1972 book on global trends in population, economics, and the environment that was translated into 28 languages and became an international bestseller. That book launched a worldwide debate on the earth’s capacity to withstand constant human development and expansion. Twenty years later, she and co-authors Dennis Meadows and Jorgen Randers reported on their follow-up study in Beyond the Limits and a final revision of their research, Limits to Growth: The 30-Year Update, was published in 2004.
