When a Latino community in Los Angeles began their fight against an oil company they claimed was polluting their neighbourhood, a young woman played a central role.
Nalleli Cobo was nine years old when she started suffering from asthma, nosebleeds and headaches.
It was the beginning of a battle against an active oil well site located in front of her house in South Los Angeles.
Nalleli and her mother soon found out that some of their neighbours were also getting sick.
The community, mostly composed of low-income families, protested until the site was temporarily shut down.
Cobo didn't stop there. Joined by a group of young activists and organisations, they sued the city to demand more regulations in oil extraction. And they won.
