  1. Causes of loss biodiversity in Tropical Rainforest • Jose Viquez, Alexis Saborio, Yullian Haspynall • spynal

  2. Impact of agriculture • Population growth forces people to migrate to find job and where to live. • They move to the latter of the rainforest so it becomes one of the most devastated parts. • Cleraing forest for cattle is the main reason for deforestation. • In many areas the quality of pasture declined considerably after a relatively short period. • Improved infra-estructure + erradication of foot-and-mouth disease = emerge of more intense cattle operations.

  3. Rainforest Burned for Agriculture

  4. Loss of Rain Forest due to Cattle • Brazil

  5. Loss of rainforest due to agriculture • Chile - Rainforest Alliance

  6. Logging • An area of forest is searched for suitable trees to be cut. • Entangled nature: when selected trees crash down they bring many others with them. • More damage - retrieval team moves in with bulldozers to haul out the selected trees. • Nothing grows where the tyre tracks ran; trees fall along the trails brought down by winds channelled. • Area is now susceptible to fire; closed canopy prevents the moist leaf litter on the floorest floor from drying enough to produce sparks but once the canopy is opened, fire becomes a real hazard.

  7. Gippsland Forest • Australia

  10. Mining • Considerable profits attracts producers to the mining industry. • A large section of rainforest tanformed into an enormous industrial park. • Decisions are being taken without the consent of natives of the region. • Natives die as a result of ‘imported’ diseases. • Independent miners invaded and polluted local rivers with mercury, used to separate gold after panning. • Air pollution has increased significantly as the scale of economic acrivity expanded.

  11. Gold mining • In the middle of the Amazon Rainforest

  12. Mining in the Malaysian Rainforest

  13. Gold Mining • Costa Rica
