A recent study has ranked the foods with the largest environmental impact, taking into account factors such as greenhouse gas emissions, water usage, and land use. The study found that beef and lamb have the highest environmental impact, followed by cheese and pork. On the other hand, fruits, vegetables, and grains have a much lower impact. The study also highlighted the importance of considering the entire supply chain when assessing environmental impact, as factors such as transportation and packaging can also contribute significantly. Overall, the study emphasizes the need for more sustainable food choices to mitigate environmental damage.
