I have to write a commentary on a speech about childrens saftey when playing in parks, and that there should be more indoor activites for them?!...

I think you need to work on presenting this as a balance
between safety outside - helmets, parental supervision, picking up trash, organizing
park clean-up days, safety patrols to look out for people who don;t belong or who are
violating park rules by drinking or doing drugs - and additional indoor activities. The
need for indoor recreation should not replace outdoor recreation. Fresh air and sunshine
are important, but on rainy days or in extreme cold an indoor dance or game of
basketball is great. Having more organized recreation such as fun leagues, too, will
keep kids focused on the activity that they are supposed to be doing, not getting in
trouble because of lack of structure and supervision. Safety comes from knowing the
rules and following the rules.
