Enjoy “In a World of Systems”, narrated and illustrated by David Macaulay (of "How Things Work") in collaboration with Linda Booth Sweeney and our team at Donella Meadows Institute. The video makes up one third of an online learning module we are designing for young change-makers who want to understand systems and change them. Sit back and meet systems in our everyday lives, from plumbing to traffic jams to fisheries, based on the work of the renowned systems thinker Donella Meadows!
