What happened

When most people picture British farming, they probably imagine fields of wheat, potatoes or vegetables stretching across the countryside.

Why it matters

But some of the food on supermarket shelves is produced in environments that look very different.

Common ground

A tomato might spend its entire life inside a glasshouse, growing more than 20 metres tall with water and nutrients delivered directly to its roots.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
