"To be vegan is a question of personal coherence. I think nobody can defend animals or environment if at the same time continues paying for the animals to be raised and killed. It´s the use of animals for food, clothes, entertainment, sport, experiments, etc. that causes the enormous animal suffering in the first place. There are also environmental reasons and social reasons to support veganism. Humans can live without using animals. It is not difficult if one is determined. Millions of people in the world already do it".Maria Luisa says.
