The nation isn't doomed to continue polluting the air and adding to the problem of global warming, which scientists say could cause severe droughts, melting glaciers and floods because of rising sea levels.
If more cities would take the initiative and promote bicycle trails, reduce sprawl, make energy-efficient building code improvements, and the like, the air pollution that causes global warming could be reduced, and the nation could get on the right track.
Environmental stewardship is a huge job, but taking it on county by county, city by city, person by person will get the job done.
