According to scientific estimates, producing a kilogram of beef requires up to 100 times more land than producing the equivalent amount of plant-based protein. This startling statistic helps explain why a vegetarian diet is a more energy-efficient choice for human consumption than one based on beef, chicken, or pork.

According to the Food and Agriculture Organization (FAO) of the United Nations, pork consistently ranks as the most widely eaten meat globally, surpassing both poultry and beef. This disparity in consumption between beef and pork is a result of a complex interplay of cultural traditions, economic factors, and regional production capacities.

Recent studies from institutions like the University of Oxford highlight that animal agriculture produces more greenhouse gases than all forms of transportation combined. It is this immense, multifaceted impact that addresses the question of why are vegans against meat, with core motivations rooted in ethical, environmental, and health concerns.

According to research from the University of Oxford, adopting a vegan diet could reduce the land used for agriculture by 75%. But beyond the global scale, many wonder: how many acres to feed a vegan on an individual level? The answer reveals a remarkable efficiency, highlighting the vast difference in resource requirements between plant-based and animal-based diets.

Over 80% of corn and soybeans in the U.S. are genetically modified, and these crops make up a large portion of conventional chicken feed. Concerns often arise regarding whether this affects the safety of the meat, especially when considering the prospect of truly genetically modified chickens..

Greta Thunberg became a vegan around the age of ten, after learning about the severe environmental impact of animal agriculture. Her choice is not merely personal but a public demonstration of her core message. As of 2025, she remains a staunch vegan, frequently emphasizing the link between dietary choices and the climate crisis.

Greta Thunberg's mother revealed in a 2020 book that the climate activist initially stopped eating most foods, not just meat, at age 11 due to depression over climate inaction. However, the young Swede later adopted a conscious, long-term vegan diet, directly linking her food choices to her environmental messaging.

According to the Vegan Society, veganism is a way of living that seeks to exclude all forms of exploitation of, and cruelty to, animals. This core principle explains exactly why vegans can eat plants but not animals, drawing a critical distinction based on sentience and suffering.

According to the Harvard T.H. Chan School of Public Health, Americans on average consume roughly 20% more protein than is recommended daily, and a significant portion comes from animal sources. While animal protein is highly nutritious, overconsumption, especially from processed and red meat, may lead to several adverse health outcomes over time.

Globally, the UN estimates livestock farming accounts for over 14% of man-made greenhouse gases, which includes methane. This often sparks the question: does meat have methane inside it? The answer is no, but the complex process by which livestock contributes to these atmospheric gases is crucial to understanding the full picture.
