Time to shift your mental thoughts to action. Turn on your reasoning and logic. No grousing, thinking is beneficial for us. Systems are our new topic. A system is a group of interacting, interrelated, or interdependent elements forming a complex whole. Consider this definition with me. A system is a group. Things in this group interact. That means there is interrelationships, cooperation. Things in a system relate to one another. They intermingle and work together. There is independence and community in a system. The last statement to make about a system is this. A system is intense. It is complex. The things forming the system are multifaceted. There are many layers in a system. A system is intricate and complicated at the same time.


On this earth there are countless systems for us to consider and understand. All of them are complex, and interactive. All are intense.

One of my favorite systems is a hardwood forest. Deciduous forests perfectly fit our system definition. Complexity is everywhere in view and everywhere unseen. The whole of a hardwood forest is intensely complex. It is also intensely beautiful. Yes, we must not forget the beauty of thousands of trees interacting with thousands of other life forms. Beauty is a clue to the answer for this complexity.DSC_0040_1071sig

 We declared  the obvious life forms, the trees. Contemplate the trees found in a hardwood forest. First a list of them: Basswood, Ironwood, Maple, Aspen, Burr Oak, Birch, Red Oak, Ash, and Hackberry are found in the forest of my example. There are other species which grow in other hardwood forests. In the large system of forests found in North America there are 950 species of trees in 81 plant families!

 Complex? Think about the root systems of the trees interlinking in the forest soil. Different species are connected by uncountable roots. More complex is the activity each of these trees must undertake to live during the growing season. Photosynthesis takes the idea of system complexity to staggering. Trees in the forest now are linked to the water cycle, the nitrogen cycle, and the sun itself. While we have written documentation of each of these systems and their functions-but the complexity is overwhelming actually. Have you considered how complex the world we live in is?DSC_0053sig

 Trees? They are the big life forms. Our eyes are drawn to them. But, the point of discussion about systems has been made: a forest is a group of interrelated but independent life forms interacting to form a complex whole: a deciduous forest. There is another consideration in wrapping up this dialogue about systems, the OTHER living things found in the hardwood forest. Dwelling with the trees-in systems are birds, migratory and year-round, mammals, insects, other flowering plants much smaller than trees, lichen, fungi, and microbes in the soil. There are reptiles and amphibians too. Yes, my limited mind has missed many other life forms found in the complex system of a hardwood forest. I did mention beauty.DSC_0016_1066sig

The purpose of this flow of information is to cause your thinking to center on the term “system.” To lead you to grapple with the immense complexity of any system in nature. Then to ask the question, “How is such intricate complexity possible?” There is a one-word answer


Use your logic, use critical thinking, or do some research. It is possible for a forest system like the one in our example and photos, to organize itself? Is there enough time in eternity that trees could organize to use sunlight, water, minerals from the soil and carbon dioxide from the atmosphere to make their own food? No grousing now either…think this through. The benefits of a correct answer are eternal. Consider this closing question and answer from Isaiah. Here is the ultimate way to comprehend the complexity of earth systems

Isaiah 40:28

Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearchable.
