There are reports of Canadian lobsters being sold this Christmas in UK ASDA and Iceland outlets at £5 a pop (http://www.theguardian.com/lifeandstyle/2014/nov/28/lobster-wars-discount-stores-slug-it-out-on-high-street-with-5-pound-shellfish). Apparently, traditional fish stocks in Canada are in a marked decline and the seas are warming up, making the lobsters (booming in numbers) accessible for longer. Lobsters largely feed on dead organic material (including dead fish?) and to be sold in the UK require to be rapidly transported by air or by sea. The refrigerated transport generates more carbon dioxide that further increases warming of the seas, killing more fish (until there is nothing much for even the lobsters to eat?). I suspect that this will be a relatively short-lived boom.
