ABSTRACT
Human society has evolved by constantly adapting to the environment around us. This constant adaptation and the need to survive in the habitat where we are located is the logic that drives the choice of the kind of food we like to eat, the fibres we use for our clothing or the temperature ranges in which we are comfortable. Since the thousands of years that have passed when the first human life originated in the African continent, human beings have essentially been facing two choices: (i) to adapt to the natural conditions that we accidentally find ourselves in, or (ii) try to modify and control these conditions. There was always a third choice, to move to a new location. But this merely brought back the first two choices afresh.
