Letters to the Editor: Animal farming costs too much for planet earth

'According to Our World in Data, if everyone shifted to a plant-based diet, we would reduce global land use for agriculture by 75%.'

Why are we still farming animals when it’s becoming increasingly clear that animal agriculture is no longer fit for purpose in our rapidly changing, climate-challenged world? 

We are locked into a system of food production about as inefficient as one could imagine. For instance, in order to produce 1kg of wheat, an average of 2.5kg of greenhouse gases are emitted, whereas a single kilo of beef creates on average 75kg of emissions.
