Anyone with any interest in man's effect on our environment must now be familiar with the term 'our global footprint', describing how much land is needed to maintain the consumption of individuals or nations, and which for the Western world, if spread over all humanity would require 2.5 planets to sustain us all.
The same exercise has been done for the amount of fish that we consume, and guess what? We are eating more fish than the world's oceans can provide.
In the case of the UK, the biocapacity available is 241.0 global hectares, unfortunately the UK 'FishPrint' demands 363.1 global hectares.
Lots of other information, and it is all explained in a report The Ecological Footprint of Nations (Measuring Humanity's impact on Marine Ecosystems) at:
