after almost 2 years in the north, i am back to my natural septentrional latitudes. as in previous visits to colombia or previous returns, the feeling of time traveling to another technological age is conspicuous. time traveling to one of the most singular countries and cities i have ever been. of course, my original city is bogota. the convergence point for all the human diversity from the country. a city, recently cataloged as one of the worst to live in the world by an international study. these international studies always reveal some true that is hidden for the locals who live immersed in the routine. but the social injustice is evident here. as is also evident in some cities of the north. imagine for instance just the homeless people of central square in cambridge, massachusetts. however, here, in colombia, in bogota, some of these homeless people have been victims of the systematic violence that rules in the rural areas of colombia. paradoxically, colombia has beautiful and rich natural resources and landscapes, but the greed and ambition of the political rulers, drug dealers, landlords, and guerrillas, have transformed this land into a war arena. sadly indeed. specially because the story of the spaniards colonizers who displaced the indigenous people back in the sixteen century seem to keep happening. greed for gold and money without caring for the social equity, for the redistribution of resources, land, money, education.
