there are many reasons as to why indigenous tribes have been forced out of the rainforest, including the construction of roads, logging, the creation of ranches, plantations and resivoirs
most displaced peoples have ended up in towns or cities and few have adjusted to this environment and addiction to drugs and alcohol has been common
once any part of the tropical rainforest is cleared, the thin topsoil is quickly removed due to the heavy rainfall, once the topsoil has been removed there is not much of a chance of anything growing there again
gold mining often goes on in the rainforest, which leads to river pollution, the mercury used to separate the gold from the ground is often allowed to enter the rivers which can impact the structure of life dramatically
selective logging
this involves felling trees only when they are fully grown, and letting younger trees mature and continue protecting the ground from erosion. it involves a cycle lasting between 30 and 40years
stopping illegal logging
given the remoteness of rainforest areas, illegal logging can easily go on unnoticed. it is still happening on a large scale. however, satellites and drones are now helping to monitor this
agroforestry
involves climbing crops and trees, by allowing crops to be grown in carefully controlled, cleared areas within the rainforest, and by growing rainforest trees on plantations outside the rainforest
replanting
a project in the atlantic rainforest of brazil (REGUA) has shown it is possible to recreate a forest cover almost like the original. they collect seeds from remaining primary patches of forest, grow the seeds into saplings and then planting the saplings back in the deforested areas
between 1999 and 2002, selective logging and general deforetation was mapped by the carnegie landsat analysis system (CLAS). in this time 46,000 kms ^2 of trees were destroyed with selective logging compared to 52,000 kms ^2 with deforestation in general
ecotourism presents a type of sustainable action. it aims to educate visitors and increase their understanding and appreciation of nature and local cultures. it is small scale and local and so its profits stay in the local community
