Disappearing of Tropical Rainforest

Disappearing of Tropical Rainforest

1. Characteristic

   • Luxuriant growth
   • Evergreen nature
   • Layered structure
   • Tree with speical features
   • Rich diversity of plant species

2. Physical enviornment

   • Temperature
   • Rainfall
     • convection rain

3. Nutrient cycling

   • Biomass = total weight of living organism (the largest)
   • Litter (the smallest)
   • Soil

4. Destruction in rainforest

   • Commerical agriculture
     • cattle ranching
     • plantation
   • Small-scale farming
     • shifting cultivation
     • subsistence farming
   • commerical logging
     • selective logging
     • clear-cutting
   • Infrastructure and mining activities
     • roads and highways
     • dams (HEP)
     • mining and oil gas exploitation

5. Cause of destruction

   • population growth
   • poverty
   • government policy
   • Shifting diet and globalized market
   • rising global price of timber
   • technological advancement

6. Effect of large-scale tropical rainforest

   • Natural envirnment
     • Atmospheric enviorment
     • Hydrosphere enviornment
     • Lithospheric environment
     • Biosphere
   • Human envionrment
     • Threat to livelihood of the native people

7. Measures to portect TRF

   • Tapping more resources from existing cleared land
   • Restore degraded forested land
   • Establish and expand protected areas
   • Control the population size
   • Eco-tourism
   • Development of the national park
