Last Sunday I woke up realising something was different. It took me a little while to realise what it was. There was no traffic noise. We can normally just hear the almost continuous traffic on Pershore Road. It is one of those things you notice when it is not there.
The reason for the quietness was that all the roads around here had been closed for the half marathon.
The previous time I had had the same sensation was on September 11th 2001. I was in the States at the time. All aircraft were grounded for several days and again it was quiet strange looking up into the sky and seeing no vapour trails. The sky was suddenly perfectly blue and clear.
Both of these instances have shown me how much we take pollution for granted whether it is noise or just vapour trails across the sky.
