Have you not heard of "Organic"? Of course nothing can be better than if you do it yourself, but there are farmers that can be trusted. In Europe and western US, people are starting to be more and more conscious about the low quality so called food we eat today and the diseases it comes along with it.
But since the objective is to make money, you cannot count so much on quality.
As for food, something I inject into my body, I would rather pay more and get a better quality even if I eat less.
