After the fires in Australia, vegetation began to recover, why do some people say that this is the b

Because the revived vegetation is eucalyptus, it occupies a position above the forest, and the branches and foliage will block the sunlight, so that the sunlight cannot reach the ground, so that the other vegetation will slow down and die due to the lack of sunlight.

Because people believe that this is nature's counterattack against humans, and people have always been ignorant of protecting nature, so one day human beings will reap the consequences of their own evil.

Personally, I think that the reason why this is the beginning of the tragedy is because nature has a relatively strong ability to repair, but we humans need to bear the consequences of it.

Australians do not reflect on their frequent fires, and vegetation is still easily ignited after it has been revived.

Scientists warn of a possible resurgence of bushfires in Australia, is this a warning from nature? Recently, the emergence of a piece of news has aroused widespread attention and discussion, and people also have a certain reflection on the appearance of this news, so what is this news? Is it nature's warning that Australia's bushfires may be back, as scientists warn of a possible resurgence of bushfires?

The way in which nature should warn human beings is worth thinking about in every one of us.

First of all, we need to know that the current ecological environment is very bad, due to the continuous development of science and technology, human beings are destroying nature more and more seriously, environmental pollution, ecological damage, resource consumption is becoming more and more serious, and this environmental problem is serious in front of everyone. Previously, the forest fire that broke out in Australia for 3 months, and the loss of financial, manpower, time, and resources was huge! Isn't this nature's counterattack against humanity?

The regeneration and recovery capacity of the natural environment ecosystem is limited and takes time.

Reverence for nature, this is what human beings should do. The ecological environment reflected on TV has been destroyed, a large number of trees have been cut down, birds have no homes, water sources have decreased, the marine environment has been polluted, and then, the punishment of nature has followed, typhoons, tsunamis, flash floods, mudslides, sandstorms, volcanic eruptions, etc., which seriously threaten the healthy life of human beings, not only that, these disasters under the punishment of nature have also caused some people to lose their lives, which is a huge blow to every family.

Looking back at the fires in Australia, is this the first warning from nature to humanity? If human beings continue to destroy the ecology endlessly, and do not plant trees in time to help nature recover, then it will be human beings themselves who will suffer next. We have been taught since childhood to be with nature as a companion and protect the earth, not to end up in this way, but to take practical actions to protect the earth, protect the natural ecology, and live in harmony with nature!

Yes, this is a warning from nature, because we are hurting nature now, hurting too much, and we are hurting nature, that is, we are hurting ourselves.

I think this is a warning from nature that we must take care of nature and not do anything that harms it.

Yes, this is the case because our nature has been destroyed before, so we must protect nature and try not to destroy it.

Eucalyptus, eucalyptus is native to the Australian continent, but because of its high medicinal value and economic value, it is cited and cultivated by many countries around the world. In China, Fujian, Guangxi, Guangdong, Yunnan and Sichuan all have some cultivation and distribution. Eucalyptus trees are very tenacious and can be reborn in a short time after such a large fire.

The cells of eucalyptus have a strong transpiration effect, which requires a high moisture content of the soil, and planting eucalyptus trees in a large area will reduce the groundwater level and the ability of the soil to retain water. Over time, the phenomenon of desertification of the soil will occur.

1. Carbon emissions increase. In the case of forest fires, in addition to the direct burning of vegetation will produce carbon emissions, incomplete combustion of combustibles after fire will produce carbon emissions again due to decomposition. It takes time for the burned soil and vegetation to recover, and it takes decades or more for new trees to grow back into storage.

2. Toxic haze. Bushfires produce toxic fumes, which are "pushed" to Australian cities with the help of strong winds. In addition to South Australia, the entire south-eastern state of New South Wales and Victoria is troubled.

Sydney's electricity supply is under threat, and masks and air purifiers are all sold out.

3. Local special weather occurs. The soot from bushfires not only browned New Zealand's glaciers, but also caused widespread heat waves and even special meteorological systems, including firespouts (where the heat of the heat causes the air to rise sharply, and cyclones draw in the air to form a convergence with the burning debris) and dry thunderstorms.

Eucalyptus. Eucalyptus trees are literally made for wildfire:

Feature 1: Eucalyptus leaves are smaller, mainly to weaken the loss of water in high temperature weather, while eucalyptus leaves and branches contain a large amount of aromatic oil (eucalyptus oil), the main component of eucalyptus oil is eucalyptol, chemical formula C10H18O, flash point is only about 50, so eucalyptus oil is very easy to slow down the fire after strong sun exposure, and eucalyptus leaves can form thick combustibles after withering, which is far more than other plants produce.

Feature 2: Eucalyptus trees generally have straight and tall trunks, branches only grow at the tips of the tree, when a wildfire occurs, the branches and leaves of other plants will be severely baked by the wildfire, and the high canopy of eucalyptus trees can prevent the flames from climbing upwards to a certain extent.

Feature 3: The eucalyptus tree has also evolved a thick bark that can withstand the roasting of the flames, and the conduit that transports nutrients is located in the center of the trunk and is tightly wrapped.

Feature 4: Generally trees are easy to lose their vitality after suffering from mountain fires, and under the bark of eucalyptus, there are some dormant buds, the conditions for waking up these buds are high temperature baking, and eucalyptus seeds have a hard shell, after the mountain fire, the shell bursts to let the tung crack, and then takes root and sprouts, so after experiencing mountain fires, eucalyptus trees can quickly occupy a favorable position.

Feature 5: Eucalyptus has an amazing growth ability, it can grow into a towering tree in just two or three years, and some species can even grow to more than 10 meters in a year, and the growth rate of eucalyptus is famous among trees.

It is because of the above characteristics, so that eucalyptus not only not afraid of fire, but "intentionally" for the wildfire to provide favorable conditions, in the Australian high temperature and little rain summer, the whole eucalyptus forest is like a "gasoline barrel", any lightning, local high temperature may cause forest fire, and once burned it is difficult to control, even the fire barrier does not work, because under the action of the wind, a trace of high temperature ash may cause another eucalyptus forest to catch fire.

The survival of the eucalyptus tree.

It can be said that eucalyptus has such characteristics, it is completely the result of biological evolution, when the forest experiences a fire, other plants either die completely, or it takes a lot of time to recover, but eucalyptus turns the wildfire into its own advantage, not only can resist the wildfire to a certain extent, but also use the wildfire to eliminate other competitors, this "self-damage 800, damage the enemy 1000" strategy, let the eucalyptus dominate the Australian forest.

Australia began to recover after the fire, but this recovery was only the resurgence of eucalyptus, which is a special species that can grow more and more in the face of fire, and each time it is burned, it will grow taller, its seeds will be able to reproduce better, and there will be more flammable substances in its leaves. The growth of eucalyptus trees also blocks the sunlight, making it impossible for vegetation on the ground to grow, and eucalyptus trees are also poisonous, and no other animals can eat them except koalas, which also creates an increased danger in Australia after the fires, and the fires in Australia will become more and more frequent, and the fires will become more and more intense.

If you look closely at the recovery from the fires in Australia, you will find that only eucalyptus trees have actually grown, and other vegetation has not grown at all, scientists say that this is the beginning of the tragedy, because eucalyptus trees are the source of the tragedy of the fires. In the face of the fire, the eucalyptus tree was not hurt by the heart, only the surface of the trunk. So after the fire, the first to revive was the eucalyptus.

Sunlight is the most important energy of life**, and eucalyptus trees are desperately trying to grow upwards in order to obtain more energy, resulting in the ground below eucalyptus trees not getting sunlight at all, resulting in other vegetation being suppressed and unable to grow.

The surgical operation of eucalyptus seeds is very hard, and it is very difficult to get it to germinate, but after the fire, the surgical operation of the eucalyptus seeds will be burned to allow the eucalyptus seeds to germinate, but the fire destroys the proteins of the unison, so that other vegetation cannot grow after the fire. As a result, the number of eucalyptus trees will increase with each fire. Because eucalyptus trees are reborn from fire, eucalyptus trees are not afraid of fire but prefer fire, and in this case, eucalyptus trees gradually evolved into leaves containing flammable oil.

In the event of a fire, eucalyptus trees can become helpers, making the fire even worse.

In addition, eucalyptus trees have deep roots below the ground, and in order to rob them of more nutrients and water, they compete with other vegetation, resulting in other vegetation not being able to grow, which disrupts nature's energy cycle.

2020 is so unlucky! Australia's vegetation is beginning to recover, but scientists believe that this is the beginning of the tragedy.

After the fires in Australia, vegetation began to recover, why is this the beginning of tragedy?

Australia's bushfires have not yet been completely extinguished, and vegetation has begun to recover, and scientists say this is not a good thing for two reasons:

Clause. First, the ecological balance may be disrupted.

Some people may be confused when they see this, but it is a gratifying thing that a vigorous sprout has grown, but why do scientists think that this is not a good thing? In fact, only one of them is not known, those trees that quickly grow new shoots are not other trees, just eucalyptus, because of the particularity of eucalyptus, so scientists say that this is not a good thing, in fact, most of the trees are not rejuvenated, only eucalyptus trees grow new shoots.

1. The ecological balance is broken

In this Australian wildfire, more than 20,000 koalas were burned to death, 150,000 hectares of kangaroo habitat lost its due vegetation, it can be said that the disaster brought by this wildfire is not only for humans, the biggest impact should be the aborigines living here, that is, the wildlife here, Australia is known for its natural ecology, there are many kinds of wildlife, and the vegetation is also diverse, but after this wildfire, the plant and animal diversity here may be broken.

Because it is only eucalyptus that is rejuvenated, and other trees do not grow new shoots, eucalyptus is very vigorous, and the germination of others is also an indication that the future may squeeze the living space of other plants, if there is only this eucalyptus in an area, it is likely that the plant diversity here will be reduced, and the corresponding animals will also suffer, eucalyptus leaves are poisonous.

Eucalyptus also has one of the biggest characteristics, that is, he is very flammable, the main ** of this wildfire may be eucalyptus, when the thunder and lightning weather eucalyptus has become a high-risk factor, the bark is too high in oil, so when the lightning hits the eucalyptus, it will cause a fire, in this germination of the tree are all eucalyptus, and the number of eucalyptus trees, the coefficient of fire will also rise.

This is because it is now mainly eucalyptus trees that are recovering. Eucalyptus is a great source of oil because it contains a lot of oil, but it protects its roots from being affected, and it is very tall enough to block the sunlight needed by other plants, so it can cause an imbalance of ecological species.

The fires in Australia have not been extinguished, and the vegetation has begun to recover, and the reason why scientists say this is not a good thing is because the fires are not extinguished and will harm the environment a lot.

If the plants start to revive before the fire is extinguished, there is a risk that it will cause another fire.
