A study recently published in the journal NatureFood has raised further concerns about excessive meat consumption and its impact on the environment. The investigation conducted by a research team from the University of Oxford analyzed the link between eating habits and environmental impact, highlighting the significant differences between those who consume high quantities of meat and those who follow plant-based diets.
The report highlights that the global food system is responsible for a significant portion of global emissions in 2015, accounting for 34% of the total. Furthermore, the food sector contributes to 70% of global drinking water consumption and 78% of water pollution. This study highlights how current meat production and consumption has a devastating impact on the environment, including the loss of biodiversity and the unsustainable use of natural resources.
To conduct the study, approximately 55,000 people were involved, divided into groups based on their eating habits. These groups included those who consumed more than 100 grams of meat per day, those who consumed up to 50 grams, fish eaters, vegetarians and vegans.
The results of the study confirmed that the increase in consumption of foods of animal origin is directly proportional to the impact on the environment. For example, the CO2 emissions generated by vegans represented only 30% of those produced by the group of those who consumed 100 grams of meat per day. However, it is important to note that the amount of meat consumed also has a significant impact: those who consumed less than 50 grams of meat per day produced only half the CO2 emissions of those who consumed more.
In summary, the study highlighted the need for significant changes in dietary habits to address global environmental challenges. Limiting meat consumption and moving towards plant-based diets could help reduce the food sector’s impact on the environment and preserve natural resources for future generations.
