The date, which is different in other parts of the world, was chosen because of the beginning of the spring, which starts on September 23 in the southern hemisphere.

How important is the tree?
the tree is a great symbol of nature and is one of the most important natural resources that we have. The various existing tree species are fundamental to life on Earth because:
- increase the air humidity thanks to evapotranspiration;
- avoid erosions;
- produce oxygen in the process of photosynthesis;
- reduce the temperature;
- provide shade and shelter for some animal species.
In addition, among the various existing tree species, there are several fruit plants, such as mango, lemon, guava, avocado, peach and orange trees.
In addition to producing food, trees also have other economic applications. The wood they produce serves as raw material for the creation of furniture and even houses. THE
cellulose extracted from these plants, mainly pine and eucalyptus, is fundamental for the production of paper. In addition, some species have applicability in the pharmaceutical industry because they have important compounds.Do not stop now... There's more after the advertising ;)
What is the purpose of Arbor Day?
Due to the large number of uses and urban expansion, trees are constantly exterminated, which results in large deforested areas. O logging it directly affects the life of the entire population, which now faces erosion, siltation of rivers, reduced rainfall and relative humidity, desertification and loss of biodiversity.
Therefore, the 21st of September should be seen as a day of reflection on our attitudes towards this important natural wealth. This day is much more than the symbolic act of planting a tree and should be seen as a moment of change in attitude and awareness that our actions affect future generations. It is also important to be aware of the importance of conservation, as well as the need to create public policies to combat illegal logging of trees.
