The role of graffitis in these countries has similarities but also has differences.  For example, in the countries of Colombia and Brazil, some of the graffitis are about political issues and corruption, in Colombia it is like a protest against violence and politician and in Brazil, it began being related to protest against the destruction of nature in favor of big cities.  On the other hand, graffitis in Honduras are not only about politics, but some street artists use internationally renowned works to get people's attention, and then they contrast these images by making additions to the drawings.  In this countries, graffiti is usually use to protest against something artist do not feel comfortable about, or to show the way people feel about different situations.
