About the author
Donella H. Meadows was an American environmental scientist, teacher, and writer. She helped make systems thinking usable beyond specialist modeling by showing how stocks, flows, delays, feedback, and purpose shape everyday outcomes.
Donella Meadows introduces elements, interconnections, purposes, stocks, flows, reinforcing loops, balancing loops, and delays. Bathtubs, thermostats, fisheries, economies, inventories, and populations make the diagrams concrete.
