A man claims ‘big oil’ caused his son’s death. Can he prove it?

From eleven-year-old activists to rural farmers, ordinary people around the world are taking on oil giants – and winning.

A case filed by an Iraqi man is the latest in a string of environmental lawsuits shaking up the oil and gas industry.

Hussein Julood is taking on UK oil giant BP over the death of his son, Ali.

Hussein claims the burning off of gas at a BP oil field emitted harmful pollutants that caused his son’s leukaemia.
