"The rate of human invention is faster, and the rate of cultural loss is slower, in areas occupied by many competing societies with many individuals and in contact with societies elsewhere"

This quote by Jared Diamond speaks with the idea that when there are many societies competing with each other, and in contact with other societies, the rate of human creation is much faster and the rate of cultural loss is slower. This is due to the fact that the competitors in between societies encourages innovation and creativity, while the contact with other societies enables the exchange of concepts and understanding. This exchange of concepts and knowledge assists to maintain cultural practices and traditions, as well as to produce new ones. In addition, the competitors in between societies can assist to avoid stagnation and the loss of cultural practices. In summary, this quote by Jared Diamond recommends that when there are lots of societies competing with each other and in contact with other societies, the rate of human invention is quicker and the rate of cultural loss is slower.
