The neighbourhood of Wilmington, California is bordered by several large freeways, three oil refineries, two of the largest ports in the United States, and is peppered with active oil wells, each dipping into the third largest oil field in the contiguous U.S. Drilling sites sit next to houses and baseball fields. Almost every street has a view of the industry.

All of this industrialisation translates to significantly higher rates of asthma and cancers for its 50,000 residents, most of whom are Hispanic.

The residents have been coming together and standing up to fight for more curbs on the extraction of oil and gas, for cleaner and safer air.
