The demand for sustainable nutrition would grow much faster if people had more money. I think that the unconditional basic income for everyone (including the working person) should be so high that everyone can afford sustainable food and so that one does not have to live on the streets, and can lead a decent life.
Yes, people should always have the freedom to say no. It would be so important to leave free, independent and self-confident thinking and acting. But unfortunately it is taught from an early age that one should say yes to everything and one should follow.
