Ancient asia & africa social contributions to society : political contributions to society: religious contributions to society: intellectual contributions to society: technological contributions to society: economical contributions to society:

A lot has been studied and said about the contributions that both ancient Asia and Africa have had on our world. As amazing as it may sound, Africa has had a great hand in many of the things that we know today, even more so than Asia. Some of these contributions are: Socially: the most important contribution came from Africa, where social equality and especially gender equality was born. It was especially important that Africa believed in the importance of both genders for all activities. Politically: In China began the establishment of social strata, led by the rulers, or emperors and in Africa, the political system was very similar. At the religious level, especially from Asia, the world received several religions, like Buddhism, one of the best known and widespread religions of all. Intellectually, especially from China, a lot of tendencies and traditions, as well as customs originated. But also from Africa, particularly from Egypt. a lot of knowledge, especially in mathematics, physics and science in general was developed. Technologically speaking, both Africa and Asia have contributed a lot. China was a huge center of technological discovery and from China we received things like printing, the use of gunpowder and many other things that were also precursors to many discoveries nowadays. But also from Africa, where metallurgy, for example, was highly developed, and according to studies, it has been discovered, that this art was passed on to other regions of the world. Finally, economically, China, being one of the most populated nations has always been a business center. But also, because of its trades in textiles and others, has always contributed grately to the world economy. But Africa has also had an impact, especially agriculturally, as it is one of the best developed activities in the world and their knowledge regarding this activity has widely affected the way that agriculture is handled worldwide.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
