Some of these cities are pretty progressive in their attempts to limit human induced climate change. We need to work harder and be louder in addressing our concerns about the impact of greenhouse gases on our childrens future health, quality of life and security. We need to also plan accordingly for impacts that are unavoidable. This means addressing urban and suburban weather-smart planning, addressing gentrification caused by middle and upper income individuals increasingly desirous of the amenities of walkable cities, supporting companies that are smart about reducing waste (of limited resources - do we even know if any resource is truly unlimited), supporting research that contributes to innovative and safe products and processes, eating sustainably produced food and demanding accessible green jobs from our elected officials. Think about how you will respond if asked 40 years from now about your role in creating the earth that our children will have inherited?
