My impression was that he was asking why it should take a young girl like Greta Thunberg to throw light on an issue that adults are neglecting. I am not here to defend Senator Craughwell but that seemed to be the thrust of his suggestion. He was not criticising Ms Thunberg but suggesting that adults had neglected the issue and it takes a young girl of 16 years to highlight an issue that all adults, politically and otherwise, have neglected for some time.
