Wall Rose is the middle Wall and not as big as wall Maria, but its twice as crowded and they're always having food shortage problems, meaning they barely have enough food to go around so alot of men go starving, since women and children get fed first. Wall Maria has completely no grass, its basically all dried dirt, which is also what makes it hard to grow enough food for everyone. Wall Maria however has a large river in it like all other walls with big boats to use to escape if needed, yet they can only use it to drink, not to water their food because it doesnt work and they need it for emergencies.
