Of course Brazil have problems, but most of them are aggravated by OTHER countries.
Prostitution, for example, is present here, and we like "export" prostitutes, NOT because the girls want, but because they are fooled to do so. Some Europeans, Americans, Brazilians, of course, etc. come here, search for low-class girls, and promise them that they could be models on other countries. Note that we are talking about LOW-CLASS girls, they are "fool", think that they will have a chance to become rich as a MODEL(Like Gisele Bündchen) and so they get convinced by them to go to Europe or US. Once there, they realize that all was a lie, and the real objective was to turn them into prostitutes. Then there's no return, they are frightened by those who took them there, and they can die, or they can become prostitutes.
About racism, I will not say it's present in Brazil. There are a few people who still have this "mental block", but younger people already have a good mind, and this doesn't occur. In Brazil there is, and I won't lie, segregation relationated to the social class. Racism is KKK, Nazism, Neo-Nazism, and what happens in Japan, where the people don't like immigrants. Here, some rich people don't like poor people, and some poor people don't like rich people. That's all.
Amazon... Well, the biggest problem is the deforestation, and most of it is made by Brazilians, but the Bio-Piratery can't be forgetted. There are many indian tribes, isolated in the forest, that can't speak Portuguese. But a big part of them speak English. The Amazon has the greatest biodiversity in the world, and some foreigners come here to discover plants WITHOUT the government permission, and use them to make chemicals, cosmetics, medicinal drugs, etc.
My opinion: the problem for Brazil was the bad colonization. After that, we've never recovered all that was lost. None of the portuguese colonies has developed well, after all, and Portugal is one of the less developed countries on Ocidental Europe. "The gold that raised palaces in Portugal, has financed the Industrial Revolution on England". This explains all.
Nothing against Americans, Europeans, and etc. I know that this all happens because of a large passivity of the Brazilian Government. :sad:
