We used intensive farming until it ruined our soils. Then we used rotation farming with heavy irrigation until it collided with a drought. We used DDT until it killed the eagles and condors. We used nitrogen fertilizers until they triggered algae blooms and ruined our waterways. I see no particular reason to expect a different pattern; we keep putting things into widespread usage before their harms are known.

I'm not even sure I'm opposed to this; most of these crises have been mitigated and most of the changes have been reactive, to accommodate a population that grew regardless of agriculture. I'm just skeptical of claims that this time, rushing things into national use without long-term evaluation won't cause any harm.
