Zanzibar seaweed industry 'at risk'

Seaweed has been one of Zanzibar's key exports since the 1990s but now it appears the industry is at risk.

The sector used to employ 23,000 people, 90% of whom were women, but in recent years a lot of the seaweed has been dying and experts suspect climate change might be to blame.
