- Changes in the environment can cause the distribution of living organisms to change
- A change in distribution means a change in where an organism lives
- Some changing environmental factors that can affect the distribution of organisms include:
- Temperature
- Availability of water
- Composition of atmospheric gases
- These changes may be seasonal, geographic or caused by human interaction
