Growing back to the roots
What weighs 6 million kilograms and is over 80,000 years old? No it's not a small planet or the largest dinosaur. It is in fact the Pando tree!
This clonal colony of quaking aspens (Populus tremuloides), also known as the 'trembling giant', is the world's biggest single living organism, as it has one massive underground root system. Well bless my Treebeard!
