There has to be a point where we draw a line under marine over-exploitation.
Ideally we should have done this some time ago, but since we haven't, we now have the perfect opportunity.
Krill, the food of numerous marine species, may over the next 50-100 years be sacrificed for an oil that has intangible human health benefits and that is available from other less important living sources.
Omega 3 oil can be obtained from linseed and flaxseed and need not be derived from a species so vital to the marine ecosystem.
The exploitation of krill is where the line needs to be drawn in the sand.
