Impact of Environment on Human Health (Strategies to alleviate…

- - - - Changes to Physical Systems & Processes
        
        heat wave
        
        heavy rains
        
        floods
        
        hurricanes
      - Changes to biological processes, timing
        
        mosquito numbers & range
        
        photosynthetic activity (reduced food yields)
      - Changes to ecosystem structure and function
        
        fisheries : consumption, yield
        
        nutrient cycles
        
        forest productiity
- - - - crop damaged
      - urban pollution & material damage
    - - malnurtition
      - weakened immune system
      - skin cancer
      - acute eye defects and cataracts
      - long term health effects
        
        exposure of fetuses to radiation and genetic mutations
- - - - Nutrient cycling
      - Soil formation
      - Primary production
    - - Food
      - Fresh water
      - Wood and fiber
      - Fuel
    - - Climate regulation
      - Food regulation
      - Disease regulation
      - Water purification
    - - Aesthetic
      - Educational
      - Recreational
- - - - Direct health impacts
        
        floods, heateaves, water shortage, landslides, increased exposure to pollutants
      - Ecosystem-mediated health impacts
        
        altered infectious diseases, reduced food yields, malnurtition, depletion of natural medicines, mental health, impoverishment, cultural/aesthetic
      - indirect, deferred and displaced health impacts
        
        diverse health consequences of livelihood loss, population displacement (slum dwelling), conflict, inappropriate adaptation and migration
- - - - Static electric & Magnetic Fields - temporary vertigo, nausea, metallic taste in mouth & perceptions of light flashes
      - Trigger nerve & muscle stimulation, changes in nerve cell excitability;
      - From base stations, wireless networks, electromagnetic hypersensitivity - Skin irritation, fatigue, heart palpitations, digestive disturbances, localized numbness etc.
      - From ELFs - Childhood leukaemia (link is currently unclear)
    - - Produce toxic free radicals (causes cell mutation)
        e.g. production of cancer cells in adults, altered fetal development that leads to deformed babies
      - Increased risk of ill-health e.g. headaches, respiratory problems, infections etc.
      - Cause substantial damage to human body tissues (skin, organs, muscles, bone, nerves)
      - Lead to death (from cancers, organ & regulatory system failure
