How and why is planning a profession that focuses on physical and social aspects of society?

There is a picture of the criteria, but the only question to be answered is: “How and why is planning a profession that focuses on physical and social aspects of society?”

I have also attached a word document of notes that I started taking, along with links to sources that I have found that have a lot of information on social/societal planning.

There is also some sources that are on my school’s website that I will have to give you my log in so you can see those.
