It was twenty years ago that I first read Eric Hansen’s classic “Stranger in the Forest: On Foot Across Borneo” and was immediately transported to a fantastical world bursting with magnificent riches. Hansen trekked almost 1,500 miles through forest so dense that the local people were pale-skinned from lack of sunlight. This world is now being relegated to the realm of fantasy — victim to the world’s growing demand for palm oil.
