Summer rises slowly from the northern forest floor. Buds burst into bouquets, injecting their sweet smell into our sterile yards and homes. Last year’s leaves slowly decompose and feed the fruits, nuts, and spices that we harvest and stock on store shelves. We feed our families tree parts.
Pancakes are covered in tree sugar. Dates, figs, olives, palm oil, cinnamon, allspice, pimento, nutmeg, and cloves all come from trees. Cocoa trees are used to make cocoa and chocolate. The berries of coffee trees yield our blessed coffee beans. Our homes are made of wood—walls, cabinets, flooring. Wood warmed our ancestors for thousands of years. Burning coals generated enough heat to extract precious metals from rock. The paper this article is printed on was a tree.
Tree seeds, apple pips, and plum stones have delicious edible tissue.
Animals including mammals (us) and birds eat the fruits and discard the seeds. Pine cones are hoarded by red squirrels. Bears help disperse seed by raiding squirrel caches. Trees feed an entire army of insects who spend their summer gnawing away at the leaves and stems.
Most showy flowering trees are insect-pollinated. Wind-pollinated trees, like evergreens, take advantage of increased wind speeds high above the ground. That is why so many pine cones are near the tree tops.
Many trees are interconnected through their root system, forming a colony. Interconnections are made by a kind of natural grafting or welding of vegetal tissues. The networking was discovered by injecting chemicals, sometimes radioactive, into a tree, and then checking for its presence in neighboring trees. They are networked. They share resources and communicate with each other. Read The Hidden Life of Trees (Peter Wohlleben) for amazing details.
We plant trees for beauty and shade from the hot sun. Trees form wind breaks, hold moisture and soil after heavy rains. They cool the air like air conditioners, and are homes to birds and mammals. New subdivisions look bare and sterile until young trees invade the neighborhood.
In the cold winters of the north, trees must grow rapidly in the short summer season when the temperature rises and the days are long. Light is limited under their dense cover and there may be little plant life on the forest floor, although fungi may abound.
The tiniest tree is a dwarf willow (Salix herbacea) found in arctic regions, maxing out at only three inches tall. A coast redwood (Sequoia sempervirens), named Hyperion after a person in Greek mythology, is no less than 380 feet tall.
I was recently on a road trip, cruising through the dry treeless southwestern states. The lack of trees amplified the heat and wind, keeping the land dry and barren. Animals, even birds, were rare. I felt relieved and most at home when I re-entered the land of trees, where the streams could flow, plants grow, and the wind is broken.
There are an estimated 3.04 trillion trees—
half in the tropics, a quarter in the temperate zones and the rest in the northern evergreen forests. About 15 billion trees are cut down annually, and about 5 billion are planted. In the 12,000 years since the start of human agriculture, the number of trees worldwide has decreased by 46%.
Many butterflies, moths and all other critters that feed mostly on trees are actually made of trees! We are what we eat. We eat trees. We too are rearranged tree stuff!
We should love our trees. We depend on them. Our lives would be miserable without them. We need to understand and support trees better. We owe them appreciation and respect.

Loved to read this, I do love / admire trees and nature. they are God’s gift to us for all the reasons you mentioned.
Thank you so much!
