Points About Trees

The most priceless works of nature are trees. Trees have been on the planet for a few million years before humans did, and they are an essential component of the ecology and how it works. Without trees, it is hard to envision any living forms existing on the surface of the world.

The advantages of trees are innumerable, but this essay will highlight 20 or more of their most remarkable contributions to help you understand why we should grow and maintain trees.

Trees Are Our Only Source of Oxygen

Earth creatures are alive because they breathe in oxygen from the atmosphere, which powers their internal organs, and exhale carbon dioxide, which is a byproduct of how the body works. The trees are nature’s sole supply of oxygen. Photosynthesis is the mechanism through which trees produce food for their survival.

This method uses airborne carbon dioxide as a raw material and turns it into oxygen as a byproduct. The percentage of this gas in the air is increased by trees, which satisfies the demand of all living things. 18 people’s worth of oxygen may be produced annually on an acre of land with mature trees.

Trees are the longest living organisms on Earth, and never die of old age

When it comes to the oldest living trees, California tops the list. The state has several gigantic sequoias and bristlecone pines that are 4,000–5,000 years old. One of the world’s oldest living trees is Methuselah, a Bristlecone Pine thought to be 4,852 years old.

Trees Absorb Other Harmful Gases

Trees clean the air by absorbing pollutants including nitrogen oxides, sulfur dioxide, ammonia, and ozone. They capture airborne particles on their barks and leaves as they filter the air.

More Than Half of All Tree Species Exist Only in a Single Country

The 2017 census not only measured the diversity of trees, but also emphasized the need for information on the locations and lifestyles of the 60,065 distinct species. The study discovered that about 58 percent of all tree species are single-country endemics, which means that each one naturally exists exclusively inside the boundaries of a single country.

The biggest numbers of endemic tree species are found in Brazil, Colombia, and Indonesia, which makes sense considering the overall richness present in these countries’ natural forests.

The study’s authors noted that the nations with the greatest number of country-endemic tree species “mirror wider trends in plant diversity (Brazil, Australia, China) or islands where isolation has resulted in speciation (Madagascar, Papua New Guinea, Indonesia)”.

Trees are Source of Food and Nutrition

Not only for humans but also for animals and birds, trees are a vital source of food and nutrients. The fruits that the trees produce are eaten by both people and other animals. If we take a closer look at our everyday activities, we can see that everything we eat—aside from meat and dairy products—comes from trees and plants.

As the animals from which these food items are derived feed on plants, grasses, and trees, even the nourishment humans obtain from meat and dairy products originates from trees. The food that trees provide us with contains all the protein, carbohydrate, and fat that the body needs to be strong and active. It also contains vitamins and minerals.

Tree rings can predict climate change

Dendrochronology is the study of tree rings to determine a tree’s age. However, a tree’s rings may show more than just the age of the tree; they can also reveal when natural calamities like volcanic eruptions or drought events occurred. The ring is thick during favorable growth years, which are highlighted by a plentiful supply of resources.

When resources are limited in the environment, it is thin. In Sikkim, India, the heat index and temperature have been rising, and a study by Somaru Ram from the Indian Institute of Tropical Meteorology revealed that this has had a negative impact on tree growth because of the high potential evapotranspiration—the rate at which plants lose water through their leaves.

These studies aid in the understanding of the effects of climate change by scientists.

Trees Didn’t Exist for the First 90% of Earth’s History

Although the Earth is 4.5 billion years old, plants may have just lately begun to populate the land, most likely as shallow-rooted mosses and liverworts. After the emergence of vascular plants around 420 million years ago, no plants rose higher than around 3 feet (1 meter) from the ground for many millions of years.

Trees Help Conserve Energy

Trees spray water onto their leaves, which are produced during the photosynthesis process, through the pores on their skin. The air is kept cool, humid, and frigid thanks to these water vapor particles. Therefore, more trees imply less heat and even less need for air-conditioning devices, which implies energy saving.

This Tree Has Been Alive Since Woolly Mammoths Still Existed

The protracted lifespan of certain trees is among their most remarkable characteristics. Many individual trees also hold their ground for hundreds or millennia at a time, while clonal colonies are known to last for tens of thousands of years—Pando Utah’s aspen forest goes back 80,000 years.

The bristlecone pines of North America are very long-lived, and one in California that is 4,848 years old (seen above) was thought to be the world’s oldest tree until 2013, when researchers revealed they had discovered a second bristlecone that had first grown 5,062 years earlier. (For reference, the last woolly mammoths perished roughly 4,000 years ago.)

The concept of a brainless plant living for 60 human lives inspires a special type of admiration among clever primates who are fortunate to reach their 100th birthday. But even when a tree passes away, it continues to be an important part of its environment.

A forest can benefit greatly from dead wood because it provides a gradual, consistent source of nitrogen and microhabitats for a variety of creatures. Dead trees are essential to up to 40% of forest fauna, including mushrooms, lichens, mosses, insects, amphibians, and birds.

Trees can help to reduce stress

According to research, being near trees is helpful for our social and mental health. According to research done by the Universities of Illinois and Hong Kong, the more thick the forest, the less stress there is. This means that strolling down a street surrounded with trees can be good for your mental health.

Additionally, studies show that being in nature makes people more compassionate. This is partially caused by the compounds they emit known as phytoncides. They can lower blood pressure, relieve anxiety, and raise pain threshold when we breathe them in.

Before Trees, Earth Was Home to Fungi That Grew 26 Feet Tall

A strange group of organisms known as Prototaxites had massive trunks up to 26 feet (8 meters) in height and 3 feet (1 meter) broad between 420 million and 370 million years ago.

A 2007 research from the University of Chicago and the National Museum of Natural History in Washington, D.C. came to the conclusion that they were fungus, not plants, despite the fact that scientists had long argued about whether they were some strange old trees.

In the present day, a 6-meter fungus would be strange enough, but at least we are accustomed to trees that are much larger, says research author and paleobotanist C.

In 2007, Kevin Boyce spoke to New Scientist. “There were no terrestrial vertebrates, little invertebrate creatures, and a few foot tall plants during the period. This fossil would have stood out even more in a smaller landscape.”

Trees Provide Shelter

Both people and animals may find fantastic refuge under trees. On the stems and branches of the trees, birds build their nests. On sweltering summer days, people may relax beneath the tree. In addition, dwellings may also be made using tree components. Homes are constructed in rural locations using tree wood, leaves, and branches.

Wood is a primary component of doors, windows, and home flooring in urban areas as well. Additionally, wood is utilized to construct furniture and even vehicles like ships. However, other materials are now used for the aforementioned objectives due to the negative impacts of indiscriminately chopping down trees for human use.

Trees can help you find your way if you get lost in the woods

The northern side of the tree trunk, which receives more shadow, is where moss will grow in northern temperate regions. The rings of a tree can also guide you in the proper path.

The tree’s rings appear to grow a little larger on the southern side, which receives more light, if you’re in the northern hemisphere. The converse is true in the southern hemisphere, where rings are thicker on the northern side.

The First Known Tree Was a Leafless, Fernlike Plant From New York

In the past 300 million years or more, a variety of plants have acquired a tree shape, or “arborescence.” It’s a challenging stage in the evolution of plants that calls for inventions like robust trunks to keep upright and powerful vascular systems to draw up water and nutrients from the earth.

But the more sunshine is beneficial, leading to convergent evolution—the numerous evolutionary waves that trees have experienced throughout time.

The oldest known tree is Wattieza, which was named after relics from the mid-Devonian era that were discovered in what is now New York and date back 385 million years. It produced the earliest known woods and was a member of an ancient plant family presumed to be ferns’ relatives. It measured 26 feet (8 meters) tall.

It might not have had leaves, but instead had frond-like branches with “branchlets” that looked like bottlebrushes (see illustration). It wasn’t closely linked to tree ferns, although it did use spores rather than seeds to reproduce.

Trees Provide Livelihood to People

People make a living by gathering and picking fruit from trees and engaging in agricultural pursuits. Numerous small company prospects are centered on agricultural goods, such as those in the food processing sector.

Large-scale businesses like the textile sector rely on the production of cotton, the sugar sector employs sugar cane as its main raw material source, and the jute sector uses jute as its only raw material to manufacture a range of goods. Then there is the handicraft sector, which employs wood to produce stunning works of art.

If a birdhouse is hung on a tree branch, it won’t move up the tree as the tree grows

This is due to the fact that trees grow top-down. Meristems are sections of the tree shoots formed by specialized cells. These meristems are the places where a tree increases its height and lengthens its limbs.

A branch will always remain the same height as it was on the day it erupted from the trunk as a tiny bud because trees develop from their most distant ends. Although many trees lose their lowest branches as they develop, just because tree branches don’t increase as a tree grows doesn’t imply they will always be there.

Some Trees Emit Chemicals That Attract Enemies of Their Enemies

Although they may appear inert and defenseless, trees are savvier than they appear. In addition to being able to create chemicals to fight off insects that feed on leaves, for example, certain species are also able to communicate with one another via chemical signals that are sent through the air, thereby alerting surrounding trees of an impending insect attack.

Numerous trees and other plants grow more resistant to insects after receiving these signals, according to research.

Even outside of the plant kingdom, information may be sent through aerial signals from trees. Some have been demonstrated to draw predators and parasites that devour the insects, thereby allowing a tree in need to appeal for help.

While studies have mostly concentrated on compounds that attract other arthropods, a 2013 research discovered that apple trees under caterpillar attack emit chemicals that attract birds that devour caterpillars.

Trees Help Save Underground Water

The greatest contributor to cloud formation and rainfall is the presence of trees. The likelihood of having the proper groundwater level is greater as precipitation increases.

In addition, trees store rain and snow in their leaves and transfer the clean water down their roots to the aquifer. The most environmentally friendly way to ensure effective groundwater conservation is to plant trees.

They Can Also Grow Above Ground or Dive a Few Hundred Feet Deep

Although supporting a tree is a difficult task, unexpectedly tiny roots frequently succeed in doing so. The majority of trees lack taproots, and the majority of their roots are located in the top 18 inches of soil, which generally has the optimum growth conditions.

The top 6 inches of soil are where more than half of a tree’s roots typically develop, but lateral development makes up for this lack of depth; the mature root system of an oak, for instance, can extend for hundreds of miles.

Even yet, tree roots differ greatly depending on the species, soil, and temperature. Bald cypress is a tree that grows near rivers and swamps. Some of its roots create exposed “knees,” which act as a snorkel by supplying oxygen to underwater roots.

Along with other adaptations including the capacity to filter up to 90% of the salt out of saltwater, some mangrove trees have similar breathing tubes called pneumatophores in their stilt roots.

However, some trees do reach astonishingly far below earth. Hickory, oak, pine, and walnut are among species that are more likely to develop a taproot, especially in sandy, well-drained soils.

Under the right circumstances, trees have been found to descend more than 20 feet (6 meters) below ground, and a wild fig in South Africa’s Echo Caves is said to have set a record for the greatest root depth ever at 400 feet.

Trees Prevent Soil Erosion

The soil on which the trees grow extremely powerfully is held by the trees’ roots. This stops soil erosion brought on by rain, flooding, and air currents.

As a result, incidents like landslides in mountainous areas tend to become less frequent. In addition, trees prevent soil erosion, which lowers pollution levels, protects fertile land from being lost, and slows the sedimentation process on rivers and streams.

A Large Oak Tree Can Consume About 100 Gallons of Water per Day

Large amounts of water are needed by mature trees, which may be problematic for orchards during a drought but is frequently beneficial for humans in general. Flooding from heavy rain can be reduced by trees absorbing water, especially in low-lying locations like river plains.

Trees can lessen the risk of erosion and property damage from flash floods by assisting the earth to absorb more water and by binding soil together with their roots.

More than 40,000 gallons of water may travel from the roots of a single adult oak to its leaves, which then release the water as vapor back into the atmosphere in a single year.

Although the rate of transpiration fluctuates throughout the year, 40,000 gallons is 109 gallons per day on average. Even more water is moved by larger trees. A huge sequoia with a 300-foot-tall trunk may perspire 500 gallons every day. And as trees release water vapor, dense forests also contribute to the precipitation.

Additionally, trees are excellent at absorbing soil toxins. According to research, one sugar maple may remove 5,200 mg of lead, 140 mg of chromium, and 60 mg of cadmium from the soil annually. Additionally, agricultural runoff has been proven to have up to 76 percent less phosphorus and 88 percent less nitrate after passing through a forest.
