Amazon rainforest major threat to the Amazon rainforest. The highway still has not been completed, limiting the environmental damage. Between 1991 and 2000, the total area of forest lost in the Amazon rose from , with most of the lost forest becoming pasture for cattle. Seventy percent of formerly forested land in the Amazon, and 91% of land deforested since 1970, is used for livestock pasture. Currently, Brazil is the second-largest global producer of soybeans after the United States. New research however, conducted by Leydimere Oliveira et al., has shown that the more rainforest is logged in the Amazon, the less precipitation
Selective logging in the Amazon rainforest ground damage but log decks and roads were small components of the overall ground damage. However, different harvest methods and techniques result in different ground damage levels. Despite similar harvest techniques, conventional logging methods produce more ground damage than reduced impact logging. Selective logging is one of the many land uses in the Brazilian Amazon, but it also increases the human access to forests through the development of a multitude of logging roads. These roads allow easier access to logging sites but also make it easier for hunters to access forest land which reduces the biodiversity within the forest. Also,
