Feeding a person on a plant-based diet takes only about a quarter as much land as feeding a typical omnivore. But there is also the issue of climate change that we should not still contribute too.

“A number of experts have called for a worldwide drop in meat consumption to tackle the climate crisis and the extreme weather patterns it is perpetuating around the world. But in 2022, one study called out Western countries, in particular, for their animal product-heavy diets. The study from the University of Bonn in Germany urged countries like the US and those in Europe where the average consumer eats around 80 kilograms of meat per year to cut meat consumption by at least 75 percent. ‘If all humans consumed as much meat as Europeans or North Americans, we would certainly miss the international climate targets and many ecosystems would collapse,’ lead researcher Matin Qaim said.”
