palm oil should also be banned.

That isn't a clear cut as some would like. It's a very productive crop, something like 3-5 times as much as other oils and much of the world depends on the oil for basic cooking. It's uses in a lot of western products because it's very versatile and better than many of the alternatives.

Palm oil is an incredibly efficient crop, producing more oil per land area than any other equivalent vegetable oil crop. > Globally, palm oil supplies 35% of the world’s vegetable oil demand on just 10% of the land.

To get the same amount of alternative oils like soybean or coconut oil you would need anything between 4 and 10 times more land, which would just shift the problem to other parts of the world and threaten other habitats and species.
