Document Summary
Often when we speak of the environmental determinants of health we don"t mean the effects of trees and fresh air. We are usually talking about the physical environment in which people live. For example: the impact of social and environmental determinants of health in polk county: safe neighborhoods. Temperatures are rising rapidly, following increases in co2 emissions and concentrations. The three graphs on this chart show changes over the past 1,000 years. The bottom graph shows carbon emissions; the beige band shows emissions due to change in land use (such as deforestation to create agricultural land) and the pink band shows fossil fuel emissions. Fossil fuel emissions have increased dramatically since the industrial revolution. The middle, beige graph shows increasing atmospheric co2 concentrations in response to increasing carbon emissions. The atmospheric concentration of co2 prior to the industrial. Revolution was approximately 280 ppm; the current concentration is nearing 390 ppm.
