what does the IMPOSSIBLE BURGER mean?

So the IMPOSSIBLE WHOPPER is a burger sold by Burger King which has no real meat.  It's made out of soy and potatoes.  It tasted very similar to a regular burger, but I could taste a subtle difference.  There's an article on the Impossible Whopper in the New Yorker.  I love/respect beef farmers.  But clearly when we talk about sustainability and carbon footprint, we have to fact the fact that the Impossible Whopper leaves a much smaller carbon footprint.
The facts clearly back that up!
