Our Built and Natural Environments/EPA webinar
- Biodiversity: For nearly all plants and animals, species diversity declines with increases in the amount of impervious surface, road density, time since development, human population density, and building density (Pickett et al. 2011).
- Water: Development in watersheds reduces the quantity, quality, and diversity of stream habitat for aquatic life (Booth and Bledsoe 2009). As water is polluted and degraded, it can become unfit for drinking, swimming, fishing, and other uses.
- Air: More than 38 percent of national carbon monoxide emissions and 38 percent of nitrogen oxide emissions come from highway vehicles. Stationary sources like power plants that provide energy to homes, offices, and industries are also major sources of pollution (EPA 2012).
- Climate Change: Greenhouse gas emissions from the transportation sector increased 19 percent between 1990 and 2010, due primarily to the increase in vehicle travel but partially offset by a slight increase in average fuel economy as older vehicles were removed from the roads (EPA 2012).
- Health: While data are lacking to determine whether the built environment determines levels of physical activity and/or obesity, nearly 90 percent of studies found a positive association (Ferdinand et al. 2012), suggesting that the built environment is one of the many factors that could play a role in how much people exercise and levels of obesity.
- Safety: Car crashes are the third leading cause of death in terms of years of life lost given the young age of so many car crash victims and the number of years they would have been expected to live if they had not died in a car crash. Only cancer and heart disease are responsible for more years of life lost (Subramanian 2011).
