Louisiana Deepwater - BP Gulf of Mexico oil spill
Robyn Bresnahan revisits the fishing families she spent time with in the aftermath of the oil spill in the Gulf of Louisiana in 2010.
A year ago, the Deepwater Horizon rig exploded in the Gulf of Mexico creating a huge oil spill.
In the aftermath, the BBC's Robyn Bresnahan spent a month in the American state of Louisiana with fishing families to see how they were affected.
She found many communities on the brink, with fishermen fearing they would never fish again.
One year on, she has returned to meet with some of the same families.
