Some of the most diverse regions in the world are found in Brazil, including the Atlantic Forest, Pantanal and Amazon. The Amazon River is one of the longest rivers in the world and the rainforest covering the Amazon Basin represents almost half of the world’s rainforests. One in every 10 existing species of plants and animals is found within the Amazon and other parts of the country.
Deforestation in Brazil, mainly a result of ongoing agricultural expansion, is threatening rare and vulnerable habitats such as the Amazon and the Atlantic Forest.
Other environmental problems facing the country include air and water pollution in Rio de Janeiro, Sao Paulo and other large cities as well as land and wetland degradation, and illegal wildlife trade.
