To add the other side. Every single one of my friends are excited for lab grown meat. The potential for a cleaner and more ethical meat plus the potential for new and better/different tasting meat is a plus for everyone in my circle.

The energy inputs alone preclude any thought of it being ethical.

What are the energy inputs and how do they compare with meat?

What aren't they, really? That's what I'd like to know.

Meat is resource intensive and certainly more resource intensive than eating vegetables directly. Meat is so inefficient that we grow most of our crops to feed meat, for example.

Why is this difference presumably not an ethical concern for you, but it is with lab-grown meat?

Differentiating on energy intensiveness sounds like an empirical claim, so I'm going to ask about the empirics.

You can't eat grass, and most ungulates can. If you're concerned about your personal footprint, it's not hard (in the US) to buy locally-raised, small-farm grass-fed beef.
