The Impact of Mercury on the Environment

Hey, I order a paper from you, but I need some correction on the paper as I got a comment from my professor.
am attaching the cases that you wrote, and my professor commented that “The case study should described in details including the introduction,  methodology,  results and discussion” what we wrote is a general one
he still need each case within 1 and 1 and half page. can you help me fixing it rapidly
