She was 9 years old.
Ella is the first official victim of air pollution in the UK.
In perfect health until the age of seven, the young Londoner began to have severe asthma and epilepsy attacks.
Faced with the death of her daughter in 2013, her mother Rosamund Kissi-Debrah did everything to understand the reasons for this sudden illness which led the little one to death.
The grieving mother had not considered pollution as the cause of her death.
She then lived near a busy highway.
Today, Ella's mother is fighting to educate the British about the sometimes unregulated pollution levels in the country.
Find his fight in the video of our partner Brut.
