- Destruction of peat bogs
- Used for compost. leads to reduction in size of the habitat
- Decay burning of peat releases carbon dioxide
- Deforestation
- Removal of forests to: Grow cattle and rice fields
- Causes of global warming
- Biological impacts of global warming
- Loss of habitat through flooding
- Changes in distribution of organisms as temperature rainfall and climate change
- Biological impacts of global warming
- Maintaining biodiversity
- Breeding programmes for endangered species
