It is difficult to define Brazil as a country; it is rather the sum of
countries with very different characteristics such as the Amazon region
with the longest river and the largest rainforest in the world, and Rio
de Janeiro, with its legendary carnival and famous beaches. In addition,
there are natural wonders such as the mighty Iguaçu Falls on the border
with Argentina, and the wetland area Pantanal, with its unique variety
of plants and animals in the west, as well as the magical desert
landscape Sertão in the northeast.
