What were the effects of transportation, trade, communication, science, and technology on the preservation and diffusion of culture?

Every technological and transport advance brings great benefits for human societies; but at the same time, it can change the cultures it links, because contact with other peoples allows human civilizations to permeate the concepts, ideas, practices, religions and customs of other cultures. Thus, with the advance of means of transportation, the cultures of the world that were previously isolated, or almost isolated, could be affected when they were mixed with ideas of other peoples. However, culture has been greatly benefited by science and technology itself, since it has knocked down myths, erroneous beliefs and harmful customs for human beings from different regions of the world. Millions of human lives were saved by modern medicine, with the creation and transportation of new medicines; as well as the transportation of properly preserved food to the most remote regions. Science and technology certainly change world cultures, but connecting the most remote peoples, even if it changes cultures, frees them from prejudice and racism, while enriching them with new concepts and discoveries.
