Top of the agenda for many big firms across Britain and the world in recent years is to find ways to help reduce their environmental footprint and become more sustainable.
This has been driven by consumer demand for change and warnings over irreversible damage by large companies, who can make small improvements to help that add up.
Marks and Spencer is the latest UK retailer to adopt vertical farming into its stores, with a selection of herbs now freshly grown and harvested in stores across London for shoppers to buy.
It has partnered with Infarm, a fast-growing vertical farming firm based in Berlin, that also now operates in other supermarket chains across Europe.
Ocado has also invested £17million in vertical farming while John Lewis plans to grow salads in store in the future in a partnership with LettUs Grow.
Aside from Marks and Spencer, Infarm has recently partnered with the online sustainable supermarket Farmdrop, which stocks a selection of herbs and salad leaves.
