Conservation in Brazil : ウィキペディア英語版 | Conservation in Brazil Even though progress has been made in conserving Brazil’s landscapes, the country still faces serious threats due to its historical land use. Amazonian forests substantially influence regional and global climates and deforesting this region is both a regional and global driver of climate change due to the high amounts of deforestation and habitat fragmentation that have occurred this region. Brazil has established an extensive network of protected areas which covers more than 2 million km2(25% of Brazil's national territory) and is divided almost equally between protected natural areas or conservation units and indigenous land ("Terras Indígenas"). Despite these measures, environmental protection is still a concern as indigenous tribes and Brazilian environmental activists contend with ranchers, illegal loggers, gold and oil prospectors and drug traffickers who continue to illegally clear forests. ==Deforestation==

The Amazon rainforest has been under direct threat of deforestation since the 1970s because of rapid economic and demographic expansion. Extensive legal and illegal logging destroy forests the size of a small country per year, and with it a diverse series of species through habitat destruction and habitat fragmentation.〔USDA Forest Service website, (Forest Service International Programs: Brazil ), retrieved February 2007.〕 Since 1970, over of the Amazon Rainforest have been cleared by logging.
