If there's a regional, national or global recession, they would topple like a rotten tree. When the global economy and stock market start to quiver, the community falls back on its local resources. A neighborhood or community can be resilient in many ways. Neighborhood patrols can reduce crime in cities and keep their area safer if police are unavailable. Church groups can look after the ill, elderly and less fortunate.
Volunteers can provide mediation services to reduce conflict among neighbors.
Gardeners can teach gardening, and schools and landlords can provide space for community gardens. The more bicycles there are, the better the transportation system will be if fuel supplies were suddenly cut short. The more people who are trained in short wave radio, CPR, first aid, and other emergency preparedness skills, the more resilient the community will be in a ANY catastrophe. Environmentalists and technologists can work together to make sure that any computer failures do not result in dangerous toxic releases near their community. Individually and collectively, we can plan to bounce back and grow stronger through hard times.
