Britain is not yet in crisis – but it is no longer in safety. For decades we have treated food security as something that happens elsewhere, to other nations, in other eras. We assumed that global markets would always function, that shipping lanes would always stay open, and that the world would always be willing to sell us what we no longer produce for ourselves.

Those assumptions are now under strain. The UK has become one of the most import dependent food economies in the developed world, and the systems we rely on are being reshaped by forces far beyond our control: energy volatility, climate disruption, geopolitical tension, and the slow erosion of domestic capacity.

This essay is not a prediction of collapse. It is an attempt to describe, plainly and without drama, the position we now occupy – and the choices we still have time to make. A nation that cannot feed itself is a nation that must trust the world to remain stable. That trust is becoming harder to justify.
