It is a unit with diversity. In different parts of the globe there have been, and still are, different types of people. Although there are more resemblances in the thinking of people regionally, there are also diverse ways of thinking within these regions.
Plurality is a characteristic of the globe.
This characteristic has caused, and is still causing, many problems in the world. However, if in order to deal with the problems we eliminate diversity, we will impoverish the world in the same way as if we would allow the extinction of a specific species, such as the bald eagle. Therefore, when a document for a global ethic is formulated, there is a need for caution, and a concern for the preservation of diversity.
