Health, climate, animals: what the research says
What eating animals does to your health, to the planet, and to them. Peer-reviewed studies and primary records. Check the data, and make up your own mind.
The documented drawbacks, in full, next to the costs of the alternative. Both halves, no cheerleading.
What a plant-exclusive diet actually requires, which nutrients need attention, and how much of each food it takes.
Every claim linked to the study behind it.
