I am writing in regard to your article “Giant fly swats could suck up motorway fumes” (27 August)

We spend all this thought on technology to diminish the frightening levels of pollution we are churning out, yet we are still so image conscious and full of ourselves that we will not give up the big cars and big houses that are, in the main, creating the problem. We should be changing attitudes towards responsibility, laziness and consumerism. There are 33,000,000 vehicles registered for use on UK roads.
