Which seems a false dichotomy as it is predicated on the assumption that chemical weed control is desirable in the first place. Simply put, all chemical weed control can bee seen as having a negative greater impact than not using them would.
Of course, reduced crop size could be seen as a negative impact just not a negative environmental impact. So, it then follows that restricting the use of all chemical weed control and not just glyphosate will result in the lowest possible environmental cost.
