ent in 1990 (Revkin, 1991), the overall situation has been very negative.
Marguerite Holloway (1993) noted that even most of the scientists that are currently studying the rainforest seem to be resigned to the loss of most of it, even while they are trying to begin to map the biological wealth of the region. Scientists and environmentalists seem to be reduced to try to save pieces of the rainforest, to fight one battle at the time to preserve a particular species or a particular local or a particular tribe of indigenous peoples.
For example, Brazilian biologist Marcio Ayres is currently attempting to save part of the Amazonian rainforest which is partially submerged for much of the year.
