The Norwegian teen fighting the government over Arctic oil
Elina Berg is a member of an environmental group suing the Norwegian government over the issuing of new oil drilling licences in the Arctic.
A Norwegian court ruled in favour of the government in January, but the activists are appealing against the decision.
The court rejected the groups' argument that the move breached the constitution, and said the risks of Arctic drilling were limited.
