oxides are released into the air when
coal is burned
- Poisonous gases such as carbon
dioxide, sulphur dioxide and nitrogen
oxides are released into the air when

- Impact on health
- Air pollution is extremely bad for
the environment and for the
health of people.
- In SA between 20 to 30 million people
breathe in air that is not safe and are
likely to develop lung diseases such as
bronchitis, pneumonia, asthma and
lung cancer
- Air pollution is extremely bad for
the environment and for the
health of people.
- Impact on the environment
- When fossil fuels such as coal, and natural gas
are burnt in power stations they produce large
amount of carbon dioxide
- In the past trees and other plants were able to
control the level of carbon dioxide by using the
gas during photosynthesis, this reaction releases
oxygen into the atmosphere
- Forests are being cut down to make way for farming and
urbanization, which means that photosynthesis decreases
so less CO2 is being used up and less O2 is being released,
this will contribute to the greenhouse effect which adds to
global warming and will bring about changes in the climate
- When fossil fuels such as coal, and natural gas
are burnt in power stations they produce large
amount of carbon dioxide
