In a coastal town in Denmark, there is a tree which took the shape of a house to shelter itself from wind. According to the photographer,
This old pink house is situated at the old dunes, a few hundred meters from the west coast, a very windy place were there isn’t much that can grow. So the tree can only grow where it has shelter.
I am not sure whether this tree was trimmed by the house owner, but in case it was not, this tree is a perfect case for Darwin’s survival of the fittest theory.
