- Humans and the environment (4.2-4.5)
- Air pollution
- Burning fuels can produce sulfur dioxide and other gases.
- Via cars and power stations.
- Forms acid rain
- Acid rain kills organisms.
- Changes soil pH, damaging roots.
- Habitats ruined.

- Habitats ruined.
- Burning fuels can produce sulfur dioxide and other gases.
- Deforestation and peat destruction
- Deforestation is needed for timber/land/agriculture
- Causes....
- More CO2 released into atmosphere.
- Less photosynthesis.
- Less biodiversity due to habitat loss.
- Purpose...
- Crops can be grown to produce biofuels.
- Increase in cattle and rice fields for food.
- Peat bogs also release CO2 when destructed.
- Land and water pollution
- Sewage must be treated properly to remove gut parasites and toxic chemicals
- Household and industrial waste is put in landfills
- Toxic chemicals leak out. Hazardous.
- Herbicides and pesticides are poisons. Many are washed into rivers.
- Same for fertilisers.
- Global warming
- In nature CO2 is released by respiration and removed by photosythesis.
- Balanced.
