According to Unification Thought, an underlying explanation for the observed harmony in nature is the concept of dual purpose. This is the principle that every entity in the universe exhibits dual purposes, simultaneously having both purposes for the whole and for the individual. The purpose for the whole means that by which the individual contributes to the preservation and development of the larger entity, and the individual purpose refers to the need to support an individual's own multiplication, development, self-preservation and self-strengthening. These purposes for the individual and the whole are not independent but interdependent.
Reflecting this principle, maples contribute to the ecosystem and to human beings, providing numerous ecological, commercial, and aesthetic values. Ecologically, they provide a habitat and food for many animals, including various lepidopteran species as well as early season source of pollen and nectar for bees. Commercially, various species are a source of timber, used for furniture, flooring, and many other products, an their sap can be used to produce maple syrup for human consumption. Aesthetically, humans plant trees for ornamental purposes and shade, and the rich colors of the autumn foliage of maple forests is a considerable tourist attraction. Both the beauty of maple trees and the taste of maple syrup and maple sugar appeal to the inner desire of human beings to experience beauty.
Human creativity has been used to create many unique cultivars of maples.
