Great is the LORD and most worthy of praise; his greatness no one can fathom. One generation will commend your works to another; they will tell of your mighty acts. They will speak of the glorious splendor of your majesty, and I will meditate on your wonderful works. They will tell of the power of your awesome works, and I will proclaim your great deeds. They will celebrate your abundant goodness and joyfully sing of your righteousness. The LORD is gracious and compassionate,
slow to anger and rich in love.The LORD is good to all; he has compassion on all he has made (Psalm 145:3-9)
Having just returned from the tree-blessed Pacific Northwest, I’m still in awe of these treasures from the hand of our Creator. No wonder that after people, trees are the most often mentioned living thing in the Bible. While they are indeed a pleasure to the eye, I’m more impressed by the work that all trees together accomplish and the benefits they provide for the remainder of the earth’s biosphere (the realm in which the living things of the earth exist). Understanding how important trees are to all of life, we may decide to change the old adage to “a tree is man’s best friend.” Here’s a list of some of the things trees do for us:
• Provide oxygen
• Moderate temperature
• Enhance rainfall—yet prevent erosion
• Collect and absorb dust and other atmospheric pollutants
• Protect the earth from rapid climate change
• Produce and protect healthy soil
• Provide food
• Provide shelter and/or cover for many animals and birds
• Provide protection for thousands of species of
sun-sensitive plants
• Provide healing products
• Provide building products
• Provide paper products
• Provide wood
• Provide fuel
• Provide sensory stimulation and the experience of beauty
• Provide living fences that hold back drifting sand and snow
• Reduce light intensity from the sun
• Provide privacy
• Protect watersheds for communities
• Produce a sense of rootedness and community
One of the joys of examining the book of God’s Works is discovering the evidence of the Creator’s unmatched intelligence and incredible ingenuity. When one examines the miracle of the tree and its function, it’s hard to believe there are scientists who deny the existence of a Creator.
The first amazing fact about the tree’s physiology is its critical part in the carbon cycle. In essence, the tree takes in sunlight, gases from the air, and water, and it produces wood, leaves, fruit, and other elements critical for all life on earth. This is the process of “photosynthesis,” a scientific term from Latin, which means “to put together with light.” And that’s exactly what happens in trees. They’re put together with light!
A greatly simplified description of the process is this: Tree leaves are green because they contain a vital substance called chlorophyll. This chlorophyll receives sunlight and mixes it with carbon dioxide from the atmosphere and water that has been drawn up from the ground through the roots, trunk, branches, and stems. This mix is turned into the carbohydrate glucose, a simple sugar. This sugar becomes the food for the tree, which through its God-given mechanisms manufactures all its critical structures—mostly wood and leaves.
In the process of doing all this work, the living factory happens to produce atmospheric oxygen as a byproduct. Blessed be the tree!
So as we putter through each day breathing out carbon dioxide and flooding the air with it from our motorized vehicles, factories, and stoves, the trees and other green plants are “breathing” it in and then “exhaling” oxygen. In a sense, trees and you and I are a team that, through give and take, support each other in our work—work that can give praise to our Creator.
Trees also demonstrate God’s lavish provision. Not only do they build their own structure and give all living things oxygen, they also produce a surplus of carbohydrates in the form of sweet sap, healing leaves and oils, and nourishing fruit, nuts, and seeds. The wood we use for our homes, our furniture, our fireplaces, our paper, and thousands of other products is the result of the work of this amazing living machine.
According to Encarta, these gifts from the tree and other photosynthesizing organisms are so abundant that about 170 billion metric tons of extra carbohydrates are produced each year. That’s a total of 30 metric tons for every person on earth! Included in this is the approximately 100 billion cubic feet of wood harvested annually from the world’s forests. If we are careful and don’t over-consume or harm forest ecosystems, there’s no reason we cannot keep our trees and our tree products


This picture of loss could be added to hundreds more that would graphically illustrate how we have failed to care for the natural world our God has entrusted to us. Even though there are many instances in which people have become aware of the damage they were doing to forests and have dramatically reversed harmful deforestation, the broad picture is still one of serious forest degradation worldwide. It may not be surprising to followers of Christ that the world in general disregards biblical mandates and foundational principles, but the truth is that the church is also responsible for the care and protection of God’s good earth.
