Even from an environmental perspective the arguments are dubious. The yields on organic food are much lower which means you need more land under production, land that could have been left to the wilderness.
There have been some rumblings about the nutrient qualities of certain food goods. You also hear about European vs. American vs. garden-grown in terms of qualitative differences. I've even seen it quantitated, indeed there was a documentary surrounding this [0]. There's a researcher that took historical records of micronutrient measures and compared them against modern cultivars, finding a decline in the per-volume contents.
I think it begs several questions about modern practices in agriculture beyond increased volume yield which is too often in the limelight. It just reminds me of Pika, which is associated with micronutrient deficiencies.
