That's true, El Pedro. Since the times I lived there (1976 to 1981) I've heard warnings from all universities and government institutions to not build in those areas, but the poor people refused to leave and continued building their rudimentary houses in all the mountains surrounding the cities, every year 10 or 20 houses were wiped off by mud and debris. That's misery and ignorance, because by cutting down the few forests and drilling sanitary pits they were digging their own graves. Not far from them, luxury residences and exclusive clubs and marinas showed off the wealth of the petroleum class. Now everything disappeared. That's Latin America, and that's what leading people don't want to see.
