STEP 1: Choose a specific product from a specific brand that you would like to purchase. (Please chose for my assignment iPhone) 

STEP 2: Conduct research about the manufacturing process and supply chain behind this product, and the business practices of the company who makes it. Find out as much as you can about where this product is manufactured, who makes it and under what conditions, and any other facts you find pertinent.
