Fighting oil pollution with art in Nigeria

"Battle Bus" was a sculpture made by Sokari Douglas Camp in memory of Nigerian environmentalist Ken Saro Wiwa and eight other activists who were controversially executed in 1995. The sculpture was seized and impounded by Nigerian port authorities in 2015 when the art work was shipped to Nigeria. Sokari Douglas Camp talks to Rebecca Kesby about growing up in the Niger Delta and how it's shaped her art work.
