Well, stop making arguments those words accurately describe.
This is nonsense. The cow that grew up on a field has been potentially exposed to all kinds of pesticides and chemicals and such, not to mention diseases. The farmers try and mitigate that, but their farms aren't closed systems, even if they're not using those things themselves.A cow that grew up on a field and wasn't fed with chemicals has the historical benefit of us knowing that it's not unhealthy, per se.
Something grown in a lab by some random company should earn my trust first. The fact it tastes the same doesn't matter to me.
Meat grown in a lab can be ensured to have no contact with any such substances. There's literally no reason at all to think it would be unhealthy; it's like saying you don't trust pennicilin because it's produced in a lab, so you're going to stick with your moldy bread compresses. It's that level of bananas.
