evidence: Overall, we found each person worldwide ate, on average, 4.5 kilograms more meat per year in 2019 than in 2000. While we can’t say what’s behind the general choice to eat more meat, our study identifies some insightful trends. [...] Despite the growing evidence and awareness of the climate impact of our diets, we found the average amount of meat – beef, poultry, pork and sheep – a person ate each year increased from 29.5kg in 2000 to 34kg in 2019. [...] Meat consumption was largely left out of the debates at the international climate change summit in Glasgow, Scotland, last month. Our study makes it clear this omission is unacceptable.
