Oceans

Page - March 6, 2008
Another area where sustainability must become central to all policy and practice is our oceans.

Some scientists have forecast the end of seafood as we know it by the middle of the century. Yet we continue to invest in wasteful and shortsighted fishing techniques.

From the whales, to coral reefs overwhelmed by coastal runoff, to tiny but ecologically vital plankton that are suffering due to climate change, our oceans are in peril.

Just as nutritionists are starting to really push the health benefits of seafood, we face a growing shortage of it. Some scientists have forecast the end of seafood as we know it by the middle of the century. Yet we continue to invest in wasteful and shortsighted fishing techniques.

The good news is that there is a way out of this predicament. What we need is a global network of marine reserves covering 40 per cent of the oceans, and now. These zones (effectively national parks at sea) would offer the most comprehensive insurance policy against overfishing and the impacts of climate change on the marine environment. Couple them with effective rules to regulate fishing in all areas outside the reserves, and you have a comprehensive roadmap to recovery for the world's oceans. To do this requires political will and clear action.

One important sign came when the United Nations passed a resolution last year demanding governments take urgent action to end the wholesale destruction of fragile deep-sea environments in international waters by bottom trawl fishing. In response, New Zealand and more than two dozen other countries agreed to strong measures to ensure that bottom trawl fishing in the South Pacific region will be effectively controlled, so that sensitive deep sea habitats are protected. Similar action has been or is being taken in other regions of the world.

These are also signs in the marketplace that we're starting to understand that feeding ourselves from the sea should not come at the expense of a healthy marine environment. Pushed by Greenpeace, some supermarkets in the UK and Europe have adopted sustainable seafood purchasing policies and removed from sale some fish species that are endangered by overfishing. For example, UK supermarket chains Marks & Spencer, Waitrose, Sainsburys and Tesco refuse to sell orange roughy to their customers. Here in New Zealand, supermarkets could adopt the same sustainable seafood purchasing policies and remove from sale fish and other seafood species that are being unsustainably fished.

Greenpeace is working to see that this happens and has already begun talking to local supermarket owners. In the meantime, consumers should talk to their supermarket managers and enquire what they're doing to ensure that the seafood they're selling comes from sustainable sources.

New Zealand's clean green image is vital and extremely valuable, but it's slipping. We've been complacent for too long, resting on the assumption the "clean green" catchphrase will see us through. It won't. The time is now to start walking the walk.

Sustainability is not just an environmental imperative; it's a moral, social and economic one as well. And it should be at the heart of every political administration, of every business, of every home.
