Summer 2019 turned out to be extremely raredestructive and brought unprecedented heat to Europe, severe flooding in the Far East, forest fires in Siberia and the Amazon. So, according to official figures, the area of Siberia's burned forests is approximately 1.3 million hectares. At the same time, light fires in South America still continue to burn, completely changing the Selva ecosystem and negatively affecting the climate on the planet. So what happens if there are no forests left on the planet?
What is the cause of forest fires?
The most powerful forest fires swept to a sizzlinga wave through the forests of the Amazon, taking with them what was once considered the lungs of the planet. Indeed, the Amazon rainforest accounts for about 20% of all oxygen production on Earth. The cause of fires is called the anthropogenic factor, or, more precisely, the human impact on the environment. The fact is that Brazilian farmers are still engaged in illegal clearing of territories for grazing cattle and buildings. For clearing, lumberjacks set fire to trees, which led to an unprecedented fire that swept the Amazon.
Despite this behavior, the Brazilian government, which accounts for most of the Amazon rainforest, is not at all struggling with such activities. On the contrary, it encourages her.

The fact is that the policy of the current presidentBrazil, Jaira Bolsonaru coincided with the increasing incidence of fires in the rain forests. Under his leadership, the government cut back on the costs of preventing illegal activities in South America's forests. Opposition of the president believes that such a move contributes to illegal deforestation and arson of forests by farmers.
So, the Brazilian National InstituteSpace research showed uncomfortable satellite data, which showed more than 72 thousand fires on the map of forests in South America. The scale of the disaster suggests that, at such a pace, the current territory of rainforests in the near future threatens to turn into a desert.
What happens if there are no trees left on the planet?
Currently, about 3 grow on the planettrillions of trees, which together provide us with the necessary amount of oxygen, wood and even food. At the same time, it is believed that during their existence on the planet, people managed to cut down more than half of all vegetation that has grown on Earth. If we imagine that the remaining trees will be cut down at one time, then humanity will not die out immediately, since there is currently a small supply of oxygen in the planet’s atmosphere. In order for a person to survive, he needs an oxygen concentration in the air of approximately 17%. Fortunately for us, the oxygen content in the Earth’s atmosphere at the moment is 21%. In other words, about 200 years must pass before we use up all the necessary oxygen.
Do you think we can stop the frightening trend of increasing forest fires? What can we do for this? Let's try to discuss this issue in our Telegram chat.
Despite the margin of time so that everyonefix, immediately after the disappearance of trees, the Earth will begin to destroy man. Floods will sharply become more frequent, extremely rapid soil erosion will occur, which will lead to the death of most crops. The rapid flow of water into rivers will lead to the death of a large number of plants and aquatic animals. Immediately after the floods, droughts will occur, resulting in a shortage of drinking water and a sharp reduction in the flora and fauna of the planet. Is it possible to survive without trees? Maybe. But not for a very long time.
