I live in Blackpool, by the sea, which you'd think would be nice clean air, however, this is not the case. If I am out walking I am particularly aware of diesel exhaust fumes. It's disgusting to breathe in. Sometimes it's suffocating. If I'm cycling to work, and depending on the weather conditions, it's a constant stench of diesel exhaust.
When I drop my son off at school, especially in the colder months, or hotter months, people keep their car engines running, and again, we are forced to breathe in this disgusting air.
Part of the problem is that lots of people were encouraged or incentivised to buy diesel, without realising the health impacts diesel has. Very sad state of affairs, but with awareness, people can make better decisions.
