Air pollution - Fossil
fuels burning to make
electricity and heat, transport
Water pollution -
Fertilisers for farming,
Land pollution - Landfill, factories
When humans build on land, they are
removing plants which photosynthesis
which removes carbon dioxide from the
atmosphere and replaces it with oxygen.
Because the humans are destroying the
plants, this is not happening as much
which results in more carbon dioxide
remaining in the atmosphere.
