The Great White shark: more threatened than threatening © CC  hermanusbackpackers

A couple of stories in the press today caught my eye. Both are about what we internally refer to as 'charismatic megafauna' (the big animals people tend to be interested in and care about), but they are also both damning indictments of our failure to protect our oceans and the life that depends on them.

Firstly – in the week of the International Whaling Commission meeting in Madeira, Portugal – whilst lots of countries get together to talk lots and try not to upset each other too much,  the BBC reports that a highly-endangered species of porpoise is being pushed ever closer to extinction.

Tesco have just announced that they're going to stop selling shark fins in their stores in Thailand.

Sharks are a dividing issue with people – some people love them and are fascinated by them, others are terrified of them. Whilst sharks have an ferocious and fearsome reputation, and any shark attack or alleged sightings of man-eating great whites off Cornwall make the news, we rarely hear of the impact we humans are having on sharks.

Greenpeace Canada exposed the country's largest grocery store chain's claims to be a 'green' grocer as false this week, after an investigation into how they source their seafood. Loblaws, whose stores account for nearly a third of all groceries sold in Canada, were found to be selling 14 of the 15 species on Greenpeace's 'Redlist' - made up of those species that are most destructively fished or farmed.

To get 'redlisted' a species must be in serious trouble, usually defined as facing a 90% reduction in numbers. Currently top of the Canadian list are Atlantic bluefin tuna, Atlantic cod, sharks, skate, shrimp and orange roughy - all of which are sold by Loblaws.
