This document provides an outline for a presentation on the contradictions between economic growth and natural limits. The presentation introduces two key concepts - the exponential growth curve and the logistic growth curve - to illustrate how limits to growth arise. It then summarizes economic history from hunter-gatherers to modern consumerism and globalization. The presentation notes that we have reached peaks in population, resources, and debt, and that continued economic growth is unsustainable. It concludes that grassroots action is needed to build local sustainable economies while larger systems unravel.
