Meat is responsible for roughly twice the greenhouse gas emissions of plant-based food. Can we afford not to seek alternative sources of protein for our food?
Arguably, the biggest one is that environmental gains from alternative proteins will be at the cost of people’s health, if processed alternative products add too much fat, salt and sugar. “In the rush forward, will plant-based proteins be the junk food of the future?” says Poppy. Ian Givens at the University of Reading, UK, says environmental benefits might be better considered in the context of the nutrition that meat alternatives offer.
For example, with milk, perhaps environmental cost could be measured per milligram of calcium, he says.“It’s extremely complicated,” says May. But he adds: “There is a real place for eco labelling.” The trickiness is in the science behind the labels – measuring emissions, how land for food production might alternatively be used, how products are shipped and so on.
