Tess loves tuna mayonnaise sandwiches. She takes them to school in her lunchbox at least twice a week
At school, her teacher talks to the class about overfishing. She explains that humans are catching too many fish, too quickly and that the fish in our seas are running out.
Tess looks at the WWF website. She finds out that in large parts of Europe, more than 70% of fish are overfished.
She also finds out that tuna is one of the most overfished species and that bluefin tuna is in danger of disappearing completely.
WWF’s website shows her how she can continue to enjoy her favourite sandwich filling, without adding to the problem of the tuna fish disappearing. She has to look for the MSC label whenever she or her family buy any fish. The label shows that the fish has been caught sustainably. This means that not too many of the fish have been taken from the same area, and that the fishermen have been careful not to damage other species or the surrounding habitat.
Tess explains what she has learnt to her mum and now they make sure they look for the MSC label whenever they go shopping. Tess still enjoys tuna fish sandwiches, but she has cheese a little more often these days!
