- Human Population Explosion
- Increased Pollution
- air
- CO2 and methane trap energy from the sun
- good in moderation, but too much leads to global warming
- Global Warming
- rising sea levels
- Habitats destroyed
- Reduced Biodiversity
- Habitats destroyed
- changes in migration patterns
- changes distribution of organisms
- e.g. each year in Africa, large numbers of giant wildebeest migrate, as the rainfall pattern changes
- e.g. the european bee-eater bird is a Mediterranean species but it is now present in parts of germany
- some species of lichen can't grow in areas where sulphur dioxide is given out by certain industrial processes
- caused by
- human interaction
- seasonal factors
- geographic factors
- changes distribution of organisms
- Reduced Biodiversity
- increases temperature
- changes distribution of organisms

- changes distribution of organisms
- changes in availability of water
- rising sea levels
- Global Warming
- good in moderation, but too much leads to global warming
- smoke + acidic gases released into the atmosphere
- acid rain
- Habitats destroyed
- Habitats destroyed
- changes composition of atmospheric gases
- CO2 and methane trap energy from the sun
- water
- chemicals to help grow crops can be washed into water
- Farming
- Global Warming
- rising sea levels
- changes in migration patterns
- increases temperature
- changes in availability of water
- rising sea levels
- drained / cleared for use as farmland
- Peat Bog destruction
- adds CO2 to atmosphere
- adds CO2 to atmosphere
- Deforestation
- to grow crops to produce biofuels
- adds CO2 to atmosphere
- less CO2 taken in
- Peat Bog destruction
- Global Warming
- Farming
- sewage + toxic chemicals from industry
- pollute lakes, rivers, oceans
- chemicals to help grow crops can be washed into water
- land
- toxic chemicals for farming
- nuclear waste buried underground
- Dumping household waste
- air
- Increased use of non renewable resources
- combustion of fossil fuels
- for raw materials (e.g. oil for plastics)
- for energy (for manufacturing processes and appliances)
- combustion of fossil fuels
- Increased Land Use to Support Population
- Housing, shops, industrial land, Quarrying
- Dumping household waste
- Farming
- drained / cleared for use as farmland
- Peat Bog destruction
- Deforestation
- to grow crops to produce biofuels
- less CO2 taken in

- Housing, shops, industrial land, Quarrying
- Increased Pollution
