It's People!

 Well... not yet anyway.

Reports of man-made 'meat' have been coming out for the last couple years.
But as food prices increase and availability decreases - maybe it's time to bring the product to market.
Sure, there will probably be some health issues or some side effects - but as most people focus on comfort and entertainment more than knowledge, usable skills or morality, maybe we've reached the apex of our civilization and we are just being prepared for the cull.
If we have already grown accustomed to the 'meat' at Taco Bell (Del Taco is much better) - can an actual Manwich be that far behind?
