If there is one thing likely to make parents like me send our children to school in a stretch limo, it is sanctimonious lectures about how not walking risks global destruction.

It is government-backed Walk to School Week, billed as “a celebration of how walking to school can reduce air pollution and help save the planet”. I admit that, when needs must, my wife, rather than the Devil, drives our daughters to the local junior school. Otherwise, I enjoy walking them – often my most strenuous exercise, and our longest uninterrupted chat. I now discover, however, that it is also meant to be my moral duty.

In the leaflet for Walk to School Week given to children, “Strider”, a cartoon talking foot, attacks car-produced “evil pollutants” that increase global warming and are “going to destroy your planet”. Strider warns children: “Each time you use a car their army gets stronger and stronger.” It’s war! So, “Come on mum,” say the multi-ethnic kids in the pictures, “let’s walk to save the world!”

Let us pass over questions about Strider’s scientific expertise at this point, since none of this has anything to do with teaching the complex science of climate change. It is about delivering a simplistic moralistic warning of man-made doom to our children – and through them, to us.

The Walk to School website even declares that “We want people to see walking to school as a great way to ‘do your bit’ in the same way as recycling your bottles or turning off lights”. When did it become the job of schools to help to forge a pseudo Blitz spirit in the Government’s “war” on global warming?

Educational crusaders are using alarmist warnings to re-educate our children in how to behave. Alan Johnson, the Education Secretary, plans to make geography lessons even more explicit morality tales about man-made global warming, in order to help to “lock in a culture change that could, quite literally, save the world”. So messing around with the curriculum or walking to school can avoid an apocalypse? In the name of global warming it seems that we are now expected to believe “quite literally” anything.

This policy of indoctrination, indoctrination, indoctrination risks raising children’s “awareness” at the expense of their education. They can end up “aware” that life on Earth is ending but ignorant of where the planet’s great rivers begin; less well-schooled in geography than in guilt-tripping their parents.

Campaigners complain that “only” 49 per cent of primary pupils walk to school. By coincidence, a survey suggests that half of 7 to 11-year-olds often lose sleep worrying about the havoc they have heard climate change will wreak. Maybe they are too scared to get out of bed – or just too tired to walk the straight and narrow path with Strider.
