Build communities that support a healthier, more physically active population, and more sustainable and enjoyable lifestyles. The pathway there, however, is very challenging. Mark Fenton is a public health, planning, and transportation consultant who is trying to help America find its way to more active and more livable cities, towns, and neighborhoods. He works with organizations and communities around the country to build environments, policies, and programs that help to create places where more people walk, bicycle, and take transit more of the time. And its not just about healthier people. Done well, active community designs lead to economically, environmentally, and socially thriving cities, towns, and rural settings where people of all ages, abilities, and incomes lead long, vibrant lives.
