In 2011, seafood company John West guaranteed consumers its tuna would be 100 percent sustainable by 2016. Unfortunately, as of now the fishing company still catches most of its fish with nets, a method that severely endangers wildlife. That’s why British multinational grocery retailer Tesco is giving John West the boot from its store. Waitrose supermarket chain is also expected to stop stocking John West tuna as well, a worthy punishment for not complying with sustainability standards. The move will not only help to protect the dwindling tuna population, but it will also alert food companies that sourcing their food in an unsustainable manner can have serious consequences for business.
