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 from initially low volume harvests of floodplains to much higher rates that remove around 25 million m3 of wood from the forest each year. The ecological, social, and economic impacts drive a better understanding of efficient forest management techniques. Logging in the Brazilian Amazon started when settlers came from Europe in the 17th century. Until the 1950s, logging was only allowed in floodplains around the main rivers and only in small portions. This changed as industrial mills started to populate the Amazon to produce sawn wood and veneer. These mills gained access to other areas of the Amazon through new
