The impact of deforestation on the exchange of water vapor and carbon dioxide between the atmosphere and the terrestrial land surface is the biggest concern with regard to the climate system, said Daley. Changes in their atmospheric concentration will have a direct effect on climate. Deforestation has decreased global vapor flows from land by 4 percent, according to a study published by the National Academy of Sciences.
Florida Wetlands are defined as: those areas that are inundated or saturated by surface water or ground water at a frequency and a duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils.
Human activities such as dredging and careless boating are threatening South Floridaâs mangroves and seagrass. Despite the valuable role that mangroves and seagrass play in the Florida Keys ecosystem, these plants are facing one particularly large threat: Us. In the Florida Keys, human development is the greatest threat to mangrove communities. Since the 1950s, more than 60 percent of mangroves in Monroe County have been destroyed for development. Activities such as dredging, using herbicides, and increasing waste water runoff have destroyed thousands of acres of mangrove habitat.
