on-sustainable agriculture in developed areas[edit]
Deforestation and increased road-building in the Amazon Rainforest are a significant concern because of increased human encroachment upon wild areas, increased resource extraction and further threats to biodiversity.
Extensive deforestation, particularly in Brazil, is of considerable worldwide concern as it is leading to the extinction of known and unknown species, reducing biological diversity and negatively impacting soil, water, and air quality. A final part of the deforestation process is the large-scale production of charcoal for industrial processes such as steel manufacturing. Soils within the region are generally shallow and cannot be used for more than a few seasons without the addition of imported fertilizers.
