Economic growth skyrocketed because the silk road became popular for trades and could trade with other countries, the environmental factors on the silk road made it good for travel, but as we know it was not that good of course there was rugged terrain, but it had to do if they wanted money for their trades, The effect of the silk road not being produced in China was that they were not getting the money and the Chinese rulers began to get very angry,There where good impacts and bad impacts but a good one is that all of the countries where getting distributed food and goods Equally but a bad impact is when another country would demand alot of goods and they would not give back their share of goods,this was dangerous for many countries because this could start wars.
