　　Second, the author assumes that economic and environmental concerns are mutually exclusive and that only enterprises motivated by economic concerns are financially rewarding. These assumptions are not supported in the argument. Moreover, there are good reasons to suspect they may be false in the case at hand. For example, while it may be true that synthetic farming methods produce significantly higher yields in the short term, it may also be the case that they fail to sustain this yield in the long term, whereas the opposite is true for organic methods. If this were the case, the financial advantage of synthetic over organic method would be illusory.

　　In conclusion, the authors prediction that yields will continue to lower for farmers who adopt organic farming methods is not well reasoned. To strengthen this forecast it would be necessary to examine and eliminate other possible factors that could account for the lower yields experienced. Lacking a full examination of these factors, it is difficult to accept the authors position. Finally, the authors view that organic farming is financially unwise is completely unsupported.
