We all agree that the pollution of our planet is growing and their every day most noticeable consequences. The growing hole in the ozone layer and the greenhouse effect are examples that demonstrate that man has not behaved very well with nature. However, there are still sites in the world that are committed to live in a cleaner, healthier environment. There are both types, and therefore rankings have been made to determine what are the cleanest and dirtiest of the world cities. Some cities that make an effort to preserve the environment and that they have been given a place among the cleanest in the world top 10 cities: Calgary in Canada, Honolulu in Hawaii, Helsinki in Finland, Ottawa in Canada and Minneapolis in United States. Find the remainder after the link. But there is another type of ranking that no city wants to join and it’s the dirtiest cities in the world. The city that took the winning post was Baku, capital of the Republic of Azerbaijan.
For those who have never heard it talk, he is a country located at the edge of the Sea Caspian, border Russia to the North, Gerogia and Armenia in the West, and Iran to the South. In second place we find the city of Ethiopia, Addis Ababa, then to the great city of Mexico, followed by the Argentine capital Buenos Aires and Antananarivo. You can see the rest of the 30 dirtiest cities in the world after the link. But imports not only cleaning or dirt from the city that is traveling, also matter to be sure. That is why I recommend to discover what are considered the most dangerous cities in the world, i.e., those which have the highest rates of crimes and killings.
