Cultural diversity and interbreeding

It is clear that the world is evolving at a speed that it has never recorded until recently; while going faster the world is evolving towards a state of possible exchanges that are more and more numerous and ever increasing. These exchanges are neither neutral nor simple; they can be described and evaluated qualitatively but it is difficult to quantify them to predict their evolution while knowing that they are inescapable: the global mass of world exchanges will increase irrepressibly. These exchanges provoke cross-fertilisation of all kinds through the diversity that characterises countries and peoples and which is the result of their past and present. To speak of the relations between times and peoples between the elements that differentiate them and those that bring them together between what the world''s population was yesterday and what it is today is invariably to introduce notions of exchanges of all kinds: the diversities of the one and the other are based on constant cross-fertilisation nourished by what is other strange different and always similar because what is human is reducible to the Same.
