Problems in neighborhoods,
1: Neighbors blast music all the time when ppl try to get their beauty sleep :/
2: Maybe crimes within a neighborhood
3: School issues within a neighbohood or like school safety if theres problems in that department bc theirs been weapons being brought to many schools...
*if i was doing this school would be my pick bc someone at my siblings old school caught the school roof on fire with like a firework.. smh
4: Littering maybe?
5: animals homeless or animal crulety in your city
6: people in your community you see or may know whom are homeless, i see pp all the time at stores asking for change, even a homeless man looking in the trash to feed himself and his dogs :(
(sorry if this not what you asked for these are just ideas, i would help write this whole thing but im kind of in the middle of a history project) :/
i hope this helps you c:
