Suggestions for a Documentary Project in Kochi

Hey everyone! So…I need to make a short 6-10 minute documentary for my college project, and I’m looking at a few topics based in Kochi. I have some ideas in mind. 1. The challenges faced by people living near coastal areas (Chellanam, Edavanakkad beach seawall issue) 2. The lives of migrant workers in Kochi 3. The struggles of sanitation workers 4. Life under a bridge: A group of homeless people living under Goshree Bridge Which of these do you think would be the most accessible to film and research? Also, if you have any other suggestions for topics, please do share.
