Adopting a vegetarian diet based around meat substitutes such as tofu can cause more damage to the environment, according to a new study.
It has often been claimed that avoiding red meat is beneficial to the environment, because it lowers emissions and less land is used to produce alternatives.
But a study by Cranfield University, commissioned by WWF, the environmental group, found a substantial number of meat substitutes – such as soy, chickpeas and lentils – were more harmful to the environment because they were imported into Britain from overseas.
The study concluded: “A switch from beef and milk to highly refined livestock product analogues such as tofu could actually increase the quantity of arable land needed to supply the UK.”
The results showed that the amount of foreign land required to produce the substitute products – and the potential destruction of forests to make way for farmland – outweighed the negatives of rearing beef and lamb in the UK.
