Block Earth's many worlds (excluding Flat) are dominated by trees. Trees are compromised of two parts, the trunk and the leaves.
There are 5 types of leaves, 4 found in naturally generating trees and 1 found in the inventory only.
Note: The fifth type of leaves (the greenest, lower left in picture) are often used for topiary.
Trees can be burned since they are made of wood and the leaves also.
