To that end, they do appear to be making a genuine effort pushing the Impossible Whopper with a television campaign and, at least in the bay area, placement on the combo board.
I thought the impossible burgers were worse for the environment than beef, and worse for you. The appeal was always 'ethical'.
I know it is similar in nutrition. If it is higher environmental impact, it is simply an economy of scale/new technology problem. It will absolutely get to the point where it is a fraction of the environmental impact as beef.
What gave you this idea? I've attempted to find corroborating evidence online and am coming up blank.
