ELI5: If Palm Oil is so bad because it requires rainforest land, why haven’t we bred Oil Palm cultivars that don’t need lots of water or can tolerate lower temperatures?

Oil Palms can be grown in a sustainable way, and that is actually done. The issue is that unsustainable oil is cheaper because you don't have to care for the future of your plantation and simply buy a new patch of cheap land.

The EU has certified rainforest friendly oil labels.

Breeding a plant to accept a different climate is extremely difficult and tons of work for decades if not centuries.
