A family, whose son has asthma and a serious heart condition, have decided to relocate to Wales after years spent living in one of the most polluted areas in Bristol.
Steph Wardle's son Cyrus is just eight years old, but will need a life-saving operation on his heart to reach adulthood. He also suffers from asthma, something his mother fears is a result of Bristol's air pollution.
Last year air pollution data was gathered across 127 sites in the city. 45 of those sites exceeded the legal limit for Nitrogen Dioxide.
Studies have found that being exposed to that level of pollution can stunt physical and mental development in children, and lead to conditions like asthma.
Bristol City Council says it is working to address the issue of air pollution as quickly as possible.
It has recently consulted on two proposals for a Clean Air Zone, which will introduce charges for high polluting vehicles in the city centre. It's expected to be implemented in March 2021.
But the Wardle family can't wait that long. They fear the Clean Air Zone will not have a significant impact on air quality in Bristol.
As a result they're uprooting their lives and moving to Porthcawl, a coastal town in Wales known for surfing.
