Being vegan is generally considered more sustainable than eating meat because plant-based diets require fewer natural resources, produce fewer greenhouse gas emissions, and have a lower impact on land and water compared to animal agriculture. Additionally, avoiding animal products can help reduce deforestation, species extinction, and water pollution associated with the meat industry.
And now, in greater depth
Being vegan is considered more sustainable than eating meat due to several reasons. Plant-based diets require fewer natural resources, produce fewer greenhouse gas emissions, and have a lower impact on land and water compared to animal agriculture. Additionally, avoiding animal products can help reduce deforestation, species extinction, and water pollution associated with the meat industry.
One of the key factors that make veganism sustainable is its minimal use of natural resources. A plant-based diet requires significantly less land, water, and energy to produce compared to animal-based diets. According to a study by the University of Oxford, switching to a plant-based diet can reduce an individual’s carbon footprint by up to 73%. This reduction in environmental impact is due to the fact that plant-based food production generally requires less land, water, and energy inputs.
Moreover, animal agriculture is a significant contributor to greenhouse gas emissions. Livestock farming, including the production of feed crops, accounts for a substantial portion of global methane and nitrous oxide emissions. Methane, in particular, is a potent greenhouse gas that contributes to climate change. The Food and Agriculture Organization of the United Nations estimates that the livestock sector is responsible for about 14.5% of global greenhouse gas emissions, which is more than the entire transportation sector.
In contrast, plant-based diets have a smaller carbon footprint. The production of fruits, vegetables, legumes, and grains generally emits fewer greenhouse gases compared to meat production. A report from the University of Oxford states that producing protein from tofu (a plant-based protein source) emits approximately 10 times less greenhouse gases than producing protein from beef.
Furthermore, the impact of animal agriculture on land and water resources is significant. Livestock farming requires vast amounts of land for grazing and growing feed crops. This leads to deforestation and habitat loss, contributing to species extinction. Animal agriculture is also a major user of freshwater resources. It takes approximately 15,415 liters of water to produce just one kilogram of beef, whereas producing one kilogram of wheat, for instance, requires only around 1,000 liters of water.
In summary, being vegan is widely recognized as a more sustainable dietary choice compared to consuming meat. It conserves natural resources, reduces greenhouse gas emissions, mitigates deforestation, protects biodiversity, and minimizes water pollution. As the well-known environmentalist Paul McCartney said, “If anyone wants to save the planet, all they have to do is just stop eating meat. That’s the single most important thing you could do.”
Here are some interesting facts on the topic:
- Livestock farming contributes more greenhouse gas emissions than the entire global transportation sector combined.
- The livestock sector uses 70% of global agricultural land.
- Animal agriculture is a leading cause of deforestation, with around 80% of deforested land in the Amazon rainforest used for cattle pasture.
- It takes around 25 kilograms of grain to produce one kilogram of beef.
- The water footprint of a vegan diet is only about one-third of that of the average American meat-based diet.

Response to your question in video format
The video looks at the difference between a vegan and meat-based diet in terms of health outcomes. It suggests that a balanced diet is more important than any one particular type of diet.
Other responses to your inquiry
Evidence shows that vegan diets tend to have far lower carbon, water and ecological footprints than those of meat- or fish-eaters. Although one Italian study found two vegan participants with extremely high eco-impacts, this turned out to be because they only ate fruit.
Isn’t
But being vegan isn’t necessarily more ethical or more sustainable than eating a diet that includes meat and other animal products. In fact, depending on people’s consumption choices, being vegan can be less ethical and less sustainable than a “normal” diet.
