Well, the problem of it being reliant on Bovine Foetal Serum seems to be <br>
just about solved, at least:<br>

The article about cultured meat being worse from the point of view of <br>
emissions was just hand-waving 'maybeism'.<br>
<br>
We'll just have to wait and see. By the time it's resolved, we probably <br>
won't need meat ourselves (as in Meat Bodies).<br>
