Globalization and Supply Chainmail

There was a time when the world was flat. The world had not yet been explored and global trade only accounted for a small portion of supply to most regions. Goods were mainly produced locally, or within a reasonable distance for them to be transported, at least before the 18^th century. This was especially true for perishable goods.  Supply chains linked consumers and suppliers to what they needed—as long as it was close, or they had the resources to bring it from far away. And it used to be that this link was just physical—moving a product from source to consumption.
