- Deforestation
- Effects
- Reduced biodiversity - unique species may die and isolation of forests affects biotic factors
- Edges of forests have different abiotic factors from middle = 'edge effect' may cause species extinction
- Soil erosion - roots hold soil together - degrades farmland, flooding, damaged aquatic ecosystems
- Effect on indigenous people - hard to change lifestyle and loss of valuable knowledge of forest species
- Loss of carbon sink - burning forests releases CO2
- Reduced rainfall downwind - more infiltration so less evapo-transpiration
- Increased ground albedo - bare ground produces wider temperature fluctuations due to less water in soil
- Loss of visual amenity (aesthetics)
- Loss of recreational/ ecotourism opportunity - lots of people can be in a forest without it seeming crowded
- Reduced biodiversity - unique species may die and isolation of forests affects biotic factors
- MEDCs and LEDCs
- Unlikely that MEDCs could have developed without deforestation occurring
- LEDCs are being criticised for going through same development as MEDCs did due to environmental impacts
- If prices of exported timber and food were raised LEDCs may be able to afford more sustainable development strategie
