What causes fires in the Amazon rainforest?

The Amazon rainforest has many fires in the dry season, because the dry season is dry, and the fire is easy to spread, the main reason is that farmers are reclaiming, the Amazon rainforest has disappeared by 25%, the forests in Argentina have almost disappeared, and the rainforest in Bolivia has long been in ruins. The situation in Peru is fine. They can't do anything, what about the Atlantic coastal forests?

95% of the area has disappeared, and what remains is a nature reserve. Before the arrival of Europeans, South America was a continent with extensive forests, and almost everywhere was full of life, even Patagonia had rich aquatic plants, and Portugal and Spain did not develop them here. In the twentieth century, South American countries became independent and deforestation, and they used their knives and axes to devastate South America, and the forests of the Brazilian highlands were weak and now semi-desert.

Actually? South America is not the worst, Africa is the continent with the most serious vegetation destruction, the poorer the country, the more serious the deforestation, the Congo rainforest is poaching, the theft of wood is serious, most of the deforestation is from countries on other continents, plus population growth. 90% of Madagascar's forests have disappeared

Because Mexico has less arable land, farmers in the Amazon will sneak into the forests to burn weeds to clear the land. In addition, during the dry season, the trees are dry, and in case of lightning weather, it is easy to start a fire.

It could be a change in the environment that caused many fires to break out in the Amazon rainforest. The environment is too polluted, so there are many changes in such weather, and natural fires are also very common.

It should be thunderstorms that make fires in the Amazon rainforest more frequent, because lightning can easily smash trees**.

As of October 2019, the Amazon rainforest fires had been extinguished, and the dry weather was an important reason for the fires.

The Amazon rainforest is located in the Amazon plain of South America, covering an area of 5.5 million square kilometers. Rainforests span nine countries: Brazil (60% of forests), Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana, Suriname and France (French Guiana), accounting for half of the world's rainforests and 20% of the world's forest area, making them the world's largest and most species-rich tropical rainforests.

The Amazon rainforest is known as the "lungs of the earth" and the "green heart".

Because the people around the Amazon rainforest are always cutting down and deforesting the forest. Therefore, the fire is brought to the forest, which causes physiological fires. Environmental protection should be a joint effort of all countries, and it is very small to rely on individual efforts.

Forests are an important part of our ecosystem. Forests not only absorb carbon dioxide from the air, but also provide us with enough oxygen. So that the living things on the earth can absorb oxygen and survive and develop normally on the earth.

However, with the progress of human science and technology, the destruction of the ecological environment has been further aggravated. The annual forest area of the world is shrinking, which directly leads to the intensification of the global greenhouse effect and the rising average temperature.

The Amazon rainforest, as the largest rainforest in the world, is the lungs of the planet. It is able to absorb a large amount of carbon dioxide every year and release a large amount of oxygen at the same time. But the Amazon rainforest has been severely damaged.

Prior to this, the number of fires in the Amazon rainforest was surging. In a short period of time, 20 percent of the Amazon rainforest has been burned by fire. And the data is still growing, and if humans don't change it, the Amazon rainforest will disappear from the face of the earth one day.

I think the reason why there are frequent forest fires in the Amazon has a lot to do with the local population. But the inhabitants always like to cut down the Amazon rainforest, which is why they bring fires to the forest. This, combined with the fact that the Amazon rainforest is wet and dry, leads directly to fires that can spread quickly and affect larger forests.

If you want to protect the environment, you can't do it alone. Therefore, it is necessary for various countries to cooperate with each other and cooperate with each other, and each country strives to achieve a certain area of afforestation. Only by working together can we unite all of us to improve our planet and increase the area of rainforests.

Due to the gradual increase in dry weather and the gradual decrease in rainfall in the past two years, the water evaporation in the Amazon rainforest has gradually increased, resulting in serious fires in the area. We should respect the environment for all living things, not wantonly destruction, and do not cultivate on a large scale.

The main reason is that the trees in the forest are flammable, and the environment is particularly dry, if there is a little fire source, serious forest fires can occur; To improve everyone's awareness of safety and fire prevention, and increase supervision, we must do a good job in fire prevention measures.

The awareness of fire prevention is not strong enough, the weather is dry, and the supervision ability is not enough; Protect the forest, don't burn, don't damage the environment, and try not to use plastic bags when shopping.

It may be caused by the relatively high internal temperature, the high temperature environment, so there will be a fire, this kind of problem is not well solved.

Since 2019, there have been 75,336 forest fires in Brazil, an 85% increase over the same period in 2018, with more than half of the fires in the Amazon rainforest. Since August 2019, there have been 36,771 forest fires, a 175% increase from the same period in July 2019. On the 23rd, Brazil** Bolsonaro signed an executive order to send troops to respond to the fire, and on the 24th, the Brazilian Ministry of Defense deployed 10,000 soldiers in the Amazon region to help extinguish the forest fire.

In the Amazon forest, the town of Sunjishu that narrowly escaped the fire has eight times more chance of dying than normal trees, and most of them die eight years after the fire.

Erika Berenguer, an ecologist at the University of Oxford and co-author of the study, said the reason for such a high mortality rate is that Amazonian species such as hardwoods and Brazilian mahogany did not evolve in flammable environments, so they do not have very thick bark or other fire-resistant mechanisms. Fire, on the other hand, is a relatively new threat that has been used for nearly a hundred years by burning forests and cutting down parts of forests to make agricultural land or timber.
