Have you seen how animals are kept in most large centralized "organic" farms? Sure they probably have a better life than at the industrial farms, but they usually are still kept in relatively small indoor spaces without free access to to land and sunshine. Their feed is still unnatural most of the time as they are fed with grains, instead of fresh grass and insects.
Harmful is anything that is unnatural. Putting chemicals into the soil is harmful. Feeding cows with grains is harmful. Injecting animals with antibiotics and vaccines that contain a lot of toxins is harmful. Restricting animals movement and access to nature is harmful. Pasteurizing fresh produce depriving it of most nutrients is harmful.
I don't have beef exclusively with Dutch farmers, my beef is with fiat agriculture in general. And I definitely don't support anything that government is doing. Not in this case, not in any other. Government regulations are responsible for creating this industrial agriculture mess in the first place.
