Meat is a staple food for many people around the world. It provides protein, iron, and other nutrients that are essential for human health. However, meat production and consumption also have a huge impact on the environment, health, and society.
Some experts argue that meat is one of the most unsustainable and unethical foods on the planet.
But what if everyone suddenly stopped eating meat? How would that affect the world? What would be the benefits and challenges of going meatless? And what are the alternatives and solutions that could make it possible?
Environmental Benefits of Going Meatless

If everyone suddenly stopped eating meat, the planet would breathe a sigh of relief. According to a 2018 study by researchers at the University of Oxford, a global shift to plant-based diets could reduce greenhouse gas emissions from food production by 49%, saving 8.1 billion tonnes of CO2 equivalent per year. This is equivalent to the annual emissions of 1.7 billion cars.
Not only that, but going meatless could also free up 76% of the land currently used for agriculture, an area the size of Africa.
This land could be used for reforestation, biodiversity conservation, or carbon sequestration, which could further mitigate climate change and prevent mass extinctions.
Additionally, a plant-based diet could reduce water consumption by 19%, as animal products require more water than crops.
This could alleviate water scarcity and improve water quality, as less animal waste and fertilizer would pollute the waterways.
Besides the environmental benefits, going meatless could also have significant health benefits for humans.
A 2019 report by the EAT-Lancet Commission, a group of 37 experts from 16 countries, found that a plant-based diet could prevent 11 million deaths per year, mainly by reducing the risk of heart disease, stroke, diabetes, and some cancers.
The report recommended that people should eat no more than 14 grams of red meat per day, which is equivalent to one small burger per week.
It also advised limiting the intake of poultry, eggs, dairy, and fish, and increasing the consumption of fruits, vegetables, nuts, seeds, legumes, and whole grains.
A plant-based diet could also help combat obesity, as it tends to be lower in calories, fat, and cholesterol than a meat-based diet.
Moreover, it could reduce the use of antibiotics in animal farming, which could slow down the emergence of antibiotic-resistant bacteria, a major threat to global health.
Challenges and Opportunities of Going Meatless
Of course, going meatless is not as simple as it sounds. There are many challenges and barriers that prevent people from adopting a plant-based diet, such as cultural preferences, social norms, economic factors, and lack of awareness.
Some people may also face nutritional deficiencies, such as iron, zinc, calcium, and vitamin B12, if they do not supplement their diet with fortified foods or supplements.
However, some many opportunities and solutions could facilitate the transition to a meatless world.
For instance, the development of plant-based alternatives, such as burgers, nuggets, sausages, and cheese, that mimic the taste, texture, and nutrition of animal products, could make it easier for people to switch without sacrificing their enjoyment.
Similarly, the emergence of cultured meat, which is grown from animal cells in a lab, could offer a more sustainable and ethical way of producing meat without harming animals or the environment.
Furthermore, the adoption of a plant-based diet could also create new economic opportunities and jobs, as the demand for plant-based products and services would increase.
Additionally, the promotion of a plant-based diet could also foster social justice and equity, as it could reduce the exploitation of animals, workers, and marginalized communities that are often involved in the meat industry.
