Covid revealed how vulnerable our food supply is. It revealed how fragile our logistics system is," says Dr Nate Storey, the co-founder and chief science officer of a US firm called Plenty.
His business utilises AI and software to create scalable, indoor "vertical farms" capable of growing multiple vegetable crops on tall walls.
Plenty aims to help relieve pressure on traditional farming as the amount of available agricultural land goes down, and the world's population - and demand for food - is rapidly rising. The world's population is expected to increase from 7.7 billion currently to 9.7 billion in 2050, according to the United Nations.
