B) Any population increase due to births should decline world wide;
For the year of 2035 it is expected that the world population will experience a decline in the birthrates, as it is expected that due to the globalization and modernization of the world the people will be having less and less children. Also, it is expected that the deaths will decline, and that will be caused by the better living conditions and improved healthcare, resulting in higher life expectancy. Since the birthrates are expected to be declining by this year all over the world, it is expected that even in the countries with high birthrates, they will be on a decline, thus resulting in much slower growing population.
Rome continued to decline after that until AD 476 when the western Roman Empire came to an end. The eastern Roman Empire, more commonly known as the Byzantine Empire, survived until the 15th century AD. It fell when Turks took control of its capital city, Constantinople (modern day Istanbul in Turkey) in AD 1453.
