The Amazon Rainforest (Brazilian Portuguese: Floresta Amazônica or Amazônia; Spanish: Selva Amazónica or Amazonía) is a moist broadleaf forest in the Amazon Basin of South America. The area, also known as Amazonia, the Amazon jungle or the Amazon Basin, encompasses 7,000,000 square kilometres (1.7×109 acres), though the forest itself occupies some 5,500,000 square kilometres (1.4×109 acres), located within nine nations: Brazil (with 60 percent of the rainforest), Peru (with 13 percent of the rainforest, second after Brazil), Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. States or departments in four nations bear the name Amazonas after it. The Amazon represents over half of the planet's remaining rainforests and comprises the largest and most species-rich tract of tropical rainforest in the world. The area is home to several diseases; Malaria, yellow fever and Dengue fever can be contracted in the Amazon region. Currently, deforestation is rising in the Amazon rainforest; at the current rate, in two decades the Amazon Rainforest will be reduced by 40%.
