Media’s Mental Pollution

I’m tired of being subjected to images like this when I wait for a train.

Questions:
– why are most fashion models children?
– why are those children sexualised?
– why do they all stand in weak unstable postures?
– high heels?
– why are they all borderline underweight?
– why do shops, advertising agencies and The London Underground think this kind of mental pollution isn’t their responsibility?
– why do we think it’s not ours?
