Ban cars near schools?

A bit radical but why not? How much air pollution should it be ok for children (and adults) to breath in every day just for a little apparent convenience? Perhaps this is something Dublin should look at too.

“You can’t play politics with people’s lives and people’s health,” said Mr Khan. “Every day action is delayed it means another young person breathing in this toxic air, an older person having breathing problems because of the poor quality of the air and literally people die. “Why can’t we work with schools and councils to have some roads outside schools where cars aren’t allowed to go? Really encourage mums, dads, carers and children to walk to school. It will be safer and you are not breathing in toxic air when playing in the playground.”
