Air pollution increases the risk of heart disease, cancer and asthma attacks and is linked to coughs and bronchitis.
Birmingham City Council has launched its consultation on its proposals for Clean Air Zones in the city.
They are proposing a Clean Air Zone (CAZ), where the most polluting vehicles will have to pay to enter the city centre: all the roads within the A4540 Middleway ring road (but not the Middleway itself).
The consultation is open until 17 August.  You can take part here
