Reflection I made a PSA about obesity with my friends Saraa and Shirin. We all helped each other do every part of the project from research to writing the script to editing. Overall, I chose to do a PSA about obesity because it is a public health issue. I think that my group and I did the entire project well. However, if I could redo, I would work on the project earlier. The most meaningful part of working on a PSA was working on it with other people. The unit of this project is public health. Public health is about preventing diseases rather than treating them. There are a lot of factors that go into public health like economy, society, and politics. Society makes the issue known to the government and then, the government and society work together using politics to get people with the right resources and mindset to make real change. These people then have to use the economy correctly to solves the issues of society. Public health is something that affects everybody and lack of care to it can damage the process of research.
