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.

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.

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.
