Thank you, Cabinet Secretary, for that answer. My question wasn't really specifically about rural schools. I possibly fogged the issue a little bit by mentioning rural schools. My question was actually about local schools, as in schools that children can walk to every day. Children who travel to school by car are exposed to an increase in pollution  of 40 per cent for that journey, compared with those who walk. Increased school runs also lead to increased pollution generally and in the vicinity of the schools. Do you agree with me that allowing school closures to go ahead is at odds with that, necessitating children to stop walking to school and be put in their parents' car or somebody else's car to be driven to school? It's at odds with the Welsh Government's claims to be serious about fighting pollution, as an increasing number of children don't live within walking distance of their nearest school.
