What do you know about the history of some holidays? Holidays usually are dates that important events happened. Here in Brazil there're 12 holidays. Most part of them are related to a catholic church saint or event. Most part of the times, Brazilians wish that holidays happen on Tuesday or Thursday. In this way they can extend weekend with the holiday. Good for health style and bad for economy. The most well known holiday is the Carnival. Approximately a week of parties all over the country. People from all over the world get in here to enjoy it. In multiple cities the government allows the people to use some streets or beaches ( depending of where you are) to the public to party. In these places usually competitions among dancing groups happen. The groups are composed by a lot of dancers and huge decorated vehicles. IMO a few things are really beautiful. But unfortunately only who lives near where the parties take place knows the another side of the coin. Sex, drugs, prostitution and many other gross things are just the start. What you watch on the television is just a small percentage of what carnival is. The crowd disturb the households and after the party is over thousands of tons of garbage are left over the streets. I don't want to generalize, a few people have fun and don't disturb anyone. Usually the government provides the necessary sanitary equipment for people to use. The problem is cultural.
