Why are you moving the goalposts? In your first post the goal was without further deforestation of rainforests, but in your reply, you changed the goal to without environmental impact. As long as global population growth is a thing, the former is possible, the latter not so much.

I’ll admit I’m not terribly interested in this topic. I only replied to your comment (at the same time as another commenter making a similar argument) because you come off as a shill for palm oil, which is odd.

Aren’t some of those plants grown in plains? I don’t think the yield per hectare is the whole story. Palm oil is tropical, leading to deforestation, but at least some of the others you listed are not.
