Just seems like pandering with very little actual environmental impact, ignoring the much more major issue with the central pillar of their business, cattle farming, which is awful for the environment.
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.
