Leif Kennair and Ellen Sandseter write in the journal Evolutionary Psychology (pdf):
We may observe an increased neuroticism or psychopathology in society if children are hindered from partaking in age adequate risky play.
Kids need places to work out their fears, the authors say, and challenging playgrounds can provide the perfect opportunity for such growth. They argue that modern Western society has an exaggerated focus on child safety, at the expense of kids' needs to figure out their personal limits.
