The most isolated tree in the world was located in the middle of the Sahara Desert in Niger.
Known as the Tree of Ténéré (or L'Arbre du Ténéré to locals, as Niger's official language is French), this small acacia tree was separated from any other trees by a distance of 250 miles. The tree was used for years as a landmark for anyone traveling through the desert until it was knocked down (allegedly) by a drunk driver in 1973. Because of course, the driver just had to hit the only thing around for miles.
