Toxic school run is poisoning children | Letters

Of course the unacceptable levels of air pollution in our cities is an issue that central and local government must urgently tackle (Report, 25 February). However, the elephant in the room is that millions of city dwellers routinely make unnecessary car journeys and they need to accept their responsibility and switch to alternative means of transport. Ironically, those children at London schools and nurseries you highlight are often being poisoned by their own parents' vehicles and those of their classmates' parents on the school run. I walk my children the mile to their school, while most of their friends are driven through the traffic-choked streets. It takes about the same time, but those families have contributed to the toxicity of the air and have done no exercise.
