Humans Influence on the Atmosphere

• Human activities- resulting changes in atmosphere


  Burning fossil fuels has increased the concentration of greenhouse gases resulting in global warming + climate change
• Impacts of human activities


  -habitat loss

  -Species extinction

  -Changes in the distribution of organisms

  -Ocean acidification, impacting marine life
• Atmospheric gases + life processes


  OXYGEN- respiration, creates energy

  NITROGEN- amino acids, proteins, DNA

  CARBON DIOXIDE- photosynthesis (light energy to chemical energy)
