Swapping animal products for future foods such as insect protein or cultured milk could reduce global warming, water and land use by over 80 per cent, a new study suggests. Researchers used computer modelling to find the optimal diet combination to meet nutritional needs, while also minimising global warming potential, water and land use. They found that if people in Europe replaced meat and dairy with foods produced through new technologies, such as making fake steak out of bovine cells, it could significantly reduce all environmental impacts. Not only that, but it would be nutritionally adequate and meet the constraints...
