Scientists: it has been shown that the adoption of new farming methods can enable some well-managed farms to reduce the use of chemical fertilizers, pesticides and antibiotics without significantly reducing or even increasing yields  Critic: that's not true  The farm you have chosen is the one that is most likely to succeed with these new methods
Why not mention farms that tried new methods but failed
Critics have no reason to assume that the failure of some farms is not caused by the quality of their soil.
