Did you know that there are 420 trees for every inhabitant of the planet? That is the good news, the bad news is that each person loses a reasonable percentage of these trees a year. It’s pretty hard to imagine how much that means, right? So, let’s try to demonstrate the benefits of trees to humans and the planet at large.
Flood and erosion control
An adult tree can absorb up to 250 liters of water per day from the soil. Imagine how they could help to avoid so many floods, which kill and leave many people without homes! Along with all this absorbed water, many nutrients from organic matter (such as animal feces) are absorbed by the roots and transformed through photosynthesis into food for the entire plant. In turn, leaves, fruits, wood and roots will serve as food for several living beings. The animals, in turn, will defecate what they ate, and the leaves and fruits that did not serve as food fall to the ground. Leaves, fruits and droppings back to the ground, and the whole cycle begins again.
The layer of leaves that form under the trees, serve as a cradle for seeds, and to protect the soil from dripping rain. Every drop of rain that falls directly on the ground causes erosion. Soil erosion can be harmful in several cases:
In rivers: Erosion takes soil and sand to the bottom (bottom) of the river, making the river shallower, with less capacity to store water, causing water shortages in low rain months, in addition to the death of fish.
For Soil: Erosion takes away seeds that could germinate and replenish natural vegetation. That is, unprotected soil tends to remain unprotected.
For animals: Erosion can take away nests of animals that make them on the ground, and cover those of several other animals, killing offspring. Furthermore, without vegetation and fruit to feed them, they go away or starve to death.
For groundwater: Soil without vegetation, as it has no roots and earthworms to make it soft, does not have a good water absorption. Furthermore, as there are no barriers to water, it will leave quickly, leaving no time for rainwater to penetrate the soil. With that, the water tables dry up, thus ending up with many rivers and consequently with our drinking water.
The canopy of trees also protects the soil from direct rain, not to mention that its roots firmly hold the soil. The roots of trees that are on the banks of rivers, sometimes appear inside the river, looking like eyelashes. These roots, in addition to preventing erosion, serve as a home for many animals. Because of these cilia, the forest near the rivers is known by the name of Mata Ciliar.
I would like to thank a great company in lancing that helped me to understand the importance of all this when I had them do some work for my family. You can see there website here for more information about them and I would recommend them. If you do need any tree related services or know someone that does, go to treeservice-lansing.com and check them out. It’s great to help a small business like them these days.
