Common claims about veganism, examined with scientific evidence. We present what the research shows — including where the evidence is uncertain or mixed.

Approximately 75-77% of global soy feeds livestock, not humans. Even the most resource-intensive plant foods produce dramatically fewer emissions, use...
“Agriculture requires animal manure and cannot maintain soil fertility without livestock.”
The Truth:
The nitrogen cycle does not require animals. Biological nitrogen fixation by legumes is the original source of soil nitrogen. Plant-based alternatives...
“Lab-grown meat technology will solve the environmental problems of animal agriculture, making individual dietary change unnecessary.”
The Truth:
Cultivated meat holds real promise but remains years from commercial scale, while the climate crisis demands emissions reductions now. The IPCC calls...
“Regenerative grazing sequesters enough carbon to offset livestock emissions, making ruminant agriculture climate-neutral.”
The Truth:
Regenerative grazing can improve soil health on individual farms, but peer-reviewed evidence overwhelmingly shows it cannot offset total livestock...
“Buying local animal products has a lower carbon footprint than importing plant foods from far away.”
The Truth:
Even accounting for transport emissions (which are larger than previously thought at ~19% of food-system emissions), what you eat matters far more...
