This document outlines a proposal to create a website called LifeCity that teaches about interdependence and sustainability. The three main goals are: 1) Teach about interdependence and how individual and community needs are met through shared resources that also create waste; 2) Help cities and communities close resource loops and eliminate waste through sustainable practices; 3) Promote information equity and computer access to support sustainability solutions. Next steps include partnering locally, developing a prototype website, recruiting experts, and researching grant opportunities.
