Abstract

We display a simplified geometrical model which aims to facilitate the understanding of current environmental problems: the sustainable complex triangular cell model. At the present stage of the human society, the cell will be represented as a scalene triangle, symbolizing distorted relationships among Energy, Economy and Ecology. By applying the concept of sustainability, it becomes possible to propose a transformation of the irregular triangle into an equilateral one, indicating a more symmetrical relationship among the 3E and, finally, the building up of a hexagonal regular community formed by these equilateral triangles. As a limiting case, one can admit a geometrical collapse of that hexagon in the case study here discussed: the recent discovering of an isolated Indian tribe at Amazon.
