In this lesson students watch and discuss the documentary of Christopher Mims called "Why Global Supply Chains May Never Be the Same" from 2022. A key focus of the documentary (which is based on the book "Arriving Today") is the relentless pursuit of the shipping industry for finding efficiencies. It is helpful for those involved in seafarers' welfare to understand how efficiencies are found, but also the impact that greater efficiency has on the people - seafarers, truckers, warehouse workers - involved in the supply chain.
