1. The deforestation
There are more than 7.7 million species of trees on the planet, and more
than 20% are in danger of extinction. As National Geographic points out, in
the last 13 years alone, deforestation has devastated 43 million hectares
around the world, massively destroying forests and jungles and causing
immense damage to soil quality.
The Spanish language dictionary (DIE). defines deforestation as "removing a
land of forest plants" in this way, it is a phenomenon caused by the impact of
human activities or natural causes, which result in the loss of forests and
jungles.
According to the 2021 deforestation fronts report, from the World Wildlife
Fund (WWF), in the last 13 years, 43 million hectares have been devastated
due to deforestation.
the loss was less severe in 2020, but deforestation continues at an alarming
rate in the tropics. Of the area lost, 3.75 million hectares were primary
tropical forests (sometimes called extant tropical forests), which is equivalent
to 10 soccer fields every minute, the WRI report.
In Chile, volcanoes and fires (deforestation in Chile is controlled by 98%, so
today there are no major losses and those that are recorded are mainly due

2. to eruptions or volcanic activity or forest fires, says veronica oyurzun, head of
the monitoring department of plant ecosystems of conaf.
Some consequences of deforestation are the following:
1. removal of tree species
2. loss of habitats
3. fire vulnerability
4. climatic alterations
5. reduction of natural resources
6. impact on sustainable tourism
7. global warming
8. loss of biodiversity
9. alterations of the water cycle
10.economic and environmental instability
Our group agrees that deforestation definitely affects the environment in
many ways such as the purification of water, and of the air that without its
purification emits carbon dioxide which favors global warming and the
destruction of the bear layer, well we have to think more about deforestation
and the dangers it produces, this has been the conclusion.
