So why have they done it?
$$$. That's the motivation for any business decision.
that dreadful fake meat that we are told we must start to eat.
Do you mean the chlorinated chicken etc, or the vegetarian imitation meat?
If the former, then again this is simple $$$, and permitted due to the fact that post-Brexit the government are free(r) to remove those pesky foods standards that are a blocker to businesses.
If the latter, then no-one is telling us to eat it. I mean, it's becoming fashionable, but that's all. There's the green angle, but I thought the main push was to get us to eat locusts etc as a cheap source of nutrients?
