Note: Biodiversity – describes the many different species that share one habitat.
When biodiversity is threaten, there you will see the effects on the environment. Habitats change over time. Some main causes are:
- A violent event;
- Gradual changes that occur over millennia such as climate change;
- Weather pattern changes;
- Human activities cause changes; and
- The introduction of alien species can have devastating effect on native wildlife.
Below is a video on factors that cause changes in a habitat. Take your notes.
