Well, I can't give you a paragraph, but here goes: If the Silk Road had never had never developed, then China wouldn't have been able to trade, travel, or communicate with other places/people. If China was totally isolated, then many things that they made would never have been made, such as gunpowder and china (plates). And if China hadn't made those things, then we would never had used them either. For example, without gunpowder, we might have not won certain wars. (Alright, I think that should get you started).
