WARNING: Do not confuse the effects of POLLUTION & DEFORESTATION.
Most students explain the effect of deforestation when the question is about pollution, or vice versa. They are different. Right now let's focus on deforestation...
Effects of deforestation to the environment:
1) SOIL EROSION
- No roots to hold the soil - soil becomes loose (2marks)
- No trees to filter rain - rain easily washes away the fertile top layer (humus) - plants cannot grow. (2marks)
- Soil becomes loose on the highlands - soil collapses. (2marks)
- When raining, washed soil from soil erosion is deposited in the river - river's water level increases. (2marks)
5) ENDANGERING FLORA & FAUNA
- habitat lose - cause EXTINCTION - give example (tiger, tapir). (2marks)
6) GLOBAL WARMING
- less trees to absorb CO2 - too much CO2 absorbs heat in a process called GREEN HOUSE effect - Earth becomes warm - ice in poles melts - sea level rises - causes climate change. (2marks)
