For one, just like any other harvestable good, it takes a lot of land and resources to grow the palm trees.
That’s only half of the issue. In fact, palm oil is entirely very space efficient compared to rape seed or other vegetable oils.
The actual issue only starts when you take into account that oil palms really only grow in south east Asia and Oceania, and the space required is obtained by cutting down rainforest.
