New technology promises to allow consumers to evaluate products (even in plastic wrap or glass). This article shows the promises and the perils associated with new technology. If the technology demands expensive testing over extended periods of time with commodity products, then we have every right to be concerned that diversity will be the victim. So yes, it would be good to be able to detect traces of pesticides on organic products or fraudulent fish, but we will also risk losing yet more biodiversity because the producers of specialty or low volume products cannot afford the profiling required to allow their products to be evaluated. That is definitely not a good thing.
