A Tzompantli is a wall full of human skulls, difficult to describe, but with a shocking effect to the adversaries of the Aztecs in Pre-Colonial times. Today it seems that nature is our enemy, we are killing entire populations of wild animals, in some cases like the Vaquita Porpoise, the smallest cetacean on the planet, we are wiping out the entire species. Like the massacres carried out by the Aztecs, this symbolic Tzompantli Vaquita will only remain as a monument of this beautiful marine mammal.
