Harry Potter star Bonnie Wright has been announced as an Oceans Ambassador for Greenpeace.

The British actress and film director previously joined scientists and campaigners investigating plastic pollution in the river Wye, and posted on Instagram 'I couldn’t be more proud of the friends and comrades I’ve met on the global @greenpeace team who work tirelessly and passionately to protect our oceans. As an ambassador I will be working to implement a united nations global oceans treaty to protect at least a third of our oceans as ocean sanctuaries'.
