Photo showing an old English oak tree (Quercus robur) slowly dying in a field, due to pollution. The top of the tree is now completely dead, with the bare branches poking through the live foliage in the shape of a burning torch flame. Old trees can take many years to finally die, due to their extensive root system and reserves.
