Trees are a by-product of oxygen

10 reasons trees are vital

Whether elegant willow, proud oak, tall pine or arid mangrove - although trees are so powerful and diverse, we hardly pay attention to them in our everyday life. Most of the time we look down, we forget to look up. There are so many reasons trees are great and vital, and why we should pay much more attention to them.

You wonder why all this? Here are our 10 reasons (in unweighted order) why trees are simply vital.

1. Trees regulate the water cycle

The water cycle is the process by which water circulates on earth. After it falls to the ground as rain, it is absorbed by trees and other plants and released back into the air through transpiration. A single tree that "drinks" continuously carries between 950-1500 liters of water back into the air every day.

This is what makes trees so important for optimal regulation of humidity. They also keep the water cycle in balance, which provides us with fresh water and keeps us alive.

Nature has developed its own rhythm of the water cycle. Deforestation disrupts this cycle immensely and puts our water supply (which only accounts for 3% of total water on earth) at risk. So far so good. Now there are still 9 more reasons trees are great.

2. Trees create jobs

From protecting the rainforest to planting trees, from harvesting to biological and botanical research. Trees create a lot of jobs. Chris spoke to Business Traveler about these jobs.

Work in the country has existed since human beings have existed. But as with a lot of other physical work, it is mostly common in low socio-economic areas. In many small, often rural communities, without trees it would be almost impossible to supply the residents.

Now the argument could come that deforestation also creates jobs. However, this type of employment is not sustainable in the long term. Once the tree is gone, so is the work. The preservation and afforestation of forests make up the majority of work with trees worldwide. We need to protect these jobs for people whose lives depend on them. Better still - create more jobs.

3. Trees are an important habitat for wild animals

We sure don't have to explain why trees are great for wildlife too, do we?

Forests serve as natural habitats for a multitude of birds, insects and mammals. These living beings have adapted to their environment over centuries and are dependent on it.

If you first think of large or exciting animals (such as elephants, tigers, gibbons, macaques or hornbills), a single tree is home to hundreds, if not thousands, of other small creatures. Snakes, frogs, millipedes, ants, termites, spiders, beetles, moths - they all depend on their home, the trees.

It is believed that if deforestation remains constant, 28,000 species will be wiped out over the next 25 years. Many of them would disappear from the earth without ever being discovered.

4. Trees improve the quality of the soil

Trees improve the quality of the soil around them in many ways. This enables them to filter carbon and other harmful substances from the earth. And that allows other plants to thrive.

High quality soil should contain no more than 2% carbon. In densely forested regions this value can even be 0.05%. In fact, on soil surrounded by trees, the harvest can be doubled. This works because the roots clean the soil. And the better the yield, the less land is needed to feed the people.

Trees also release important minerals into the ground because they shed their leaves. This can be broken down into mulch.

And finally, trees improve the quality of the soil by drawing nutrients from the depths to the surface through their strong roots. This, in turn, makes the soil much more nutritious to other crops (including crops).

In short, if we want good soil for agriculture and biodiversity, we have to take care of the trees on our planet.

5. Trees prevent soil erosion

Deforested areas are much more prone to desertification. With their solid trunks and dense leaves, trees form a natural barrier against wind and flooding. This barrier weakens natural forces and prevents bad weather from turning into natural disasters that destroy large areas.

In the Philippines, we focus on planting mangrove trees. These trees form a natural protection of the land.

Tree roots have the important function of holding the soil together and preventing erosion. In deforested areas without them there is nothing to keep the soil in place. The speed of incoming winds or monsoons can therefore not be slowed down. If there is constant strong wind or rain, the entire loose soil is swept away and the area is turned into a quasi-desert.

6. Trees as a source of food

Trees are a natural source of many vital foods. It is common knowledge that if everyone were vegan, the world's population would have more than enough to eat.

We can draw many nutrients from trees alone. They range from nuts and fruits to syrups made from flowers and resins. Spices made from aromatic bark such as cinnamon are also included. Trees are an incredibly abundant source of food for humans.

And hey - with the firewood they provide, we can prepare food that would otherwise be indigestible to us. One of the many reasons trees are great is because they give us so many vital things.

7. Trees reduce noise

Just as trees fight air pollution, they play an important role in reducing noise pollution. Noise is a major effect of urbanization, traffic and industrialization. Not only is it a nuisance to humans, it also has devastating effects on the animal world.

On the one hand, man-made noise disturbs animal sonar and navigation systems. On the other hand, it can mess up entire ecosystems. For example, some breeding birds do not nest in areas with higher noise pollution.

The leaves of the trees have a sound-absorbing effect. By buffering the volume of ambient noise, the wildlife is protected from noise. Noise that will be produced by humans.

8. And light pollution

Not only as a buffer for noise, foliage also serves as a barrier against unwanted light pollution.

Just like noise, light pollution is more than a nuisance in cities. It also disrupts animal habitats. As nocturnal mammals, species such as birds, moths and badgers are dependent on a daily cycle of light and darkness. This regulates their internal clock and helps them find their way around and forage.

Newly planted trees help reduce the effects of pollution around the world.

9. Trees fight climate change

One factor influencing global warming and climate change is the level of carbon dioxide in our atmosphere. Carbon dioxide is a greenhouse gas that is known to store heat. On a rapidly warming planet, man-made excess carbon dioxide literally traps the heat in our atmosphere.

When a tree grows, it absorbs carbon dioxide from the air during what is known as photosynthesis. It stores carbon in the wood and releases oxygen molecules. For this reason, forests act like huge filter systems. Trees remove greenhouse gases from the air and don't release them until they're burned or composted back into the earth.

This is why the effects of deforestation are two-fold. Not only are

Because of this, deforestation has two negative effects. Not only are the natural CO² filters removed, they are often burned afterwards, releasing the carbon they have stored back into the atmosphere.

When a tree is fully grown, it barely filters any carbon dioxide from the atmosphere. Less new wood is produced and no further carbon is required. With responsible forest management, older trees can be carefully felled to absorb the maximum amount of carbon from the air. This creates a “carbon sink”.

Trees are crucial in the fight against climate change. Without the forests of this world we would have no chance.

10. Trees produce oxygen

There is a lot of truth in the adage that the Amazon rainforests are the green lungs of our planet. We already know how trees filter CO² from the air. An additional advantage of trees is that they produce oxygen as a by-product. So trees not only remove unhealthy air, they even replace it with clean air.

Considering that two-thirds of the human body is made up of oxygen, that's pretty good news! Without a constant supply of oxygen, our days would be numbered. And since photosynthesis is our greatest source of oxygen, we should do everything we can to protect our trees!
