introduction of contaminants
cause adverse change
Water pollution
contamination of water resources
EFFECTS
water is polluted with unacceptable levels of harmful chemicals
plants are unable to carry out photosynthesis
disruption in food chains
typhoid, cholera, hepatitis
destruction of the entire ecosystems
CAUSES
discharge of harmful substances into rivers
nitrate fertilisers are easily washed off fields by rain
and flushed into rivers etc.; cannot be removed from the water
industrial plants dump waste into rivers etc.
domestic sewage (disease-causing microorganisms)
accidental oil spills
Soil contamination
land degradation
alteration in the natural soil environment
EFFECTS
decreases the agricultural output of the land
various human and animal diseases
destruction of the entire ecosystems
CAUSES
human-made chemicals
agricultural chemicals
industrial activity
improper disposal of waste
Air pollution
air pollutants
EFFECTS
long-term exposure to air pollution
contributes to premature deaths
