It's hosting the 2016 Summer Olympic Games, Has one of the biggest cities in the world, Rio de Janero, which I probably just butchered the name of, which contains the Christ Statue. Contains a large section, if not all of the Amazon and Amazonian River. Also has Sao Paulo and the capitol is Brasilia, which was an attempt to draw people into the interior part of the country. Largest speaker of Portuguese in the world and the fifth largest by both land and population. Birthplace of Pele.
Now I didn't use any outside sources and I'm sure some of this is wrong.
