Big as it is, close to land, the beast can no longer hold everything in its stomach.

Among other things, acidity affects how quickly shellfish and other species can calcify – build their shells or skeletons. At predicted rates, mussels are expected to calcify their shells 25% more slowly than at present, oysters, 10% slower. While many aquatic organisms are adapted to temperature fluctuations, ocean acidity hasn’t changed much in millions of years and nobody really knows how they will react to the projected variations. Dirty water – pollution and other threats Human activity has a significant impact on the marine environment and resources.

The government therefore launched a competition to find a way of preserving food for the soldiers. In 1809 Nicolas Appert came up with the winning entry – canning. The US had commercial canneries by 1818, Britain a few years later. Sardine canneries opened in France in 1825.

One lesson to be drawn from this story is that fishing is part of a wider industry – what we now call the agro-food sector.
