Build a Stock and Flow model of the Mayan Civilization collapse using Symlin. Based on Forrester’s classic D-memo, this experiment walks you through identifying stocks, flows, and delays behind systemic overshoot. Download our Scribe PDF and start modeling collapse.

Issue #7 explores Earth as a living system, honoring Laudato Si’ Week. We start with vision—introducing the EHBI index—then unpack Pope Francis’ loops in Laudato Si’ and the global stories from The Letter. You’re invited to turn insights into simulations using Symlin and reflect on how collapse is feedback from our common home.

Ten years after Laudato Si’, we trace Pope Francis’s vision as a system of feedback loops. From collapse to care, the encyclical becomes a blueprint for balancing economy, ecology, and ethics—revealing how our choices reinforce or regenerate our common home.

Collapse is not failure—it’s feedback. This month, we explored systemic breakdowns and Pope Francis’ call to reconnection. Next issue? Zombies, contagion, and SIR loops. See you in Boston at ISDC!

The Letter reveals how climate, inequality, and institutional failure are deeply connected. Through Ridhima’s story and others, we explore how systemic listening can shift us from despair to co-designed hope.

Welcome message for the Systems and Stories Fifth Issue dedicated to the Guelaguetza.

This is the wrapper for April's Issue of Systems Stories.
