In the media, and for educational purposes, we often make a comparison between birds and humans. If one imagines a Northern Fulmar of the size (body mass) of a human, the contents of its stomach can be multiplied by about a hundred to visualize what is going on.
From that perspective, the human sized fulmar from the North sea flies around with on average a lunchbox full of plastic in its stomach. We now distribute our information flyer on this issue in three languages. The photographs may be downloaded separately.
