How could veganism change the world?

Global Food System Challenges and Projections

• By 2050, the global population is projected to approach 10 billion, necessitating a 60% increase in food production.
• The current food system contributes approximately 25% of all greenhouse gas emissions, consumes 70% of global freshwater, and occupies 40% of Earth's land surface.
• Without intervention, food-related emissions could rise to 50% of the total global emissions budget by 2050, exceeding limits required to avoid dangerous climate change levels.
• If the entire world adopted a vegan diet by 2015, estimated food-related greenhouse gas emissions would have decreased by 75%.
• If the world transitions to a vegan diet by 2050, premature and all-cause mortality rates could drop by 20% due to improved dietary health.
• A global shift to a plant-based diet by 2050 could save approximately $1 trillion annually, representing 3% of total global healthcare costs, primarily by reducing coronary heart disease, stroke, cancer, and diabetes.
• Currently, global meat consumption grows by nearly 3% annually since 1960, despite rising awareness of environmental and animal welfare issues.
• A predominantly plant-based diet is estimated to achieve 75% of the emissions reductions needed to stay below dangerous climate thresholds, though a full transition to veganism is considered unlikely by 2050.
• The environmental impact of cattle is severe: they are the third-largest greenhouse gas emitter globally if ranked as a country, producing methane via digestion and driving deforestation for pasture.
• Farmland efficiency is heavily skewed toward animal production: over 80% of global farmland supports only 18% of world calories, with 2/3 of agricultural land used as pasture.
• Feeding conversion rates are inefficient, requiring 10kg of grain to produce 1kg of beef, 6kg for pork, and 3-4kg for chicken.
• A complete transition to veganism could free land equivalent in size to the African continent by converting pastures.

Business Shifts and Industry Adaptation

• Jaap Korteweg, a ninth-generation Dutch farmer, transitioned from livestock farming to plant-based meat production 11 years ago to address the inefficiency of animal agriculture.
• Korteweg's company, "The Vegetarian Butcher," ships products to 17 countries with annual sales reaching €20 million.
• The company utilizes standard meat-factory equipment to replicate the texture and taste of beef using plant ingredients like soy, lupine, wheat, and peas.
• Existing meat processing firms and butchers have adopted plant-based lines as customers and partners, noting that supply chains allow for relatively easy pivots from animal to plant production.
• Market trends suggest wealthy nations may reach "peak meat" consumption, driven by affordable and accessible alternatives, though this has not yet become a global reality.
• Korteweg predicts that the agricultural sector will continue to evolve, analogizing the transition from draft horses to machinery as a precursor to machines replacing slaughter animals, leaving only wild populations.
• The transition is driven by the observation that consumers desire the sensory experience of meat but lack a preference for the environmental and ethical costs of animal production.

Policy and Future Outlook

• Governments are identified as crucial actors in facilitating dietary shifts through updated dietary guidelines and public procurement policies prioritizing plant-based, healthy, and sustainable foods.
• Experts warn that without large-scale movement toward plant-based diets, the probability of staying below dangerous climate change levels becomes "very slim."
• While a fully vegan world by 2050 is deemed unlikely based on historical trends, incremental shifts toward plant-based diets are viewed as necessary and beneficial.
• The industry anticipates a future where animal slaughter becomes obsolete, similar to the extinction of draft workhorses, replaced entirely by industrial production methods.
• A well-balanced vegan diet is projected to offer varied nutrition with fewer calories, directly contributing to public health improvements and economic savings.
