Bluefin tuna is an endangered species, and it's the oceanic equivalent of a tiger, rhino, or panda - yet it is still being served up as expensive sushi in restaurants. In London alone, there are dozens of venues serving up bluefin, although the celebrity hang-out Nobu is probably the most high-profile culprit.
Our politicians have failed on bluefin tuna, they ignore the scientific warnings, and continue to set quotas that are then ignored by the fishermen.
If we want to stop bluefin from becoming extinct in just a few years then we need to take action now.
