I am a vegan...because...
If any other product caused more pollution than all of the motor vehicles in the world (cars, ships, planes), caused suffering of sentient beings on a massive scale, provided horrible conditions for underpaid workers, was the #1 reason for deforestation around the world, loss of biodiversity, loss of land to provide enough food for the people who live on this planet-- was an entity stronger and more powerful than oil, and whose advertising messages are designed to look like health messages (they lie).. if any other product was all of those things, would you support it?
I don't judge people for what they eat; But I do want people to think about what they eat.
