Wandering earth began this passage, and now it seems to have another taste! Only when you are there can you have a deep understanding.
From the fire season in late July last year to today, Australia is suffering from the worst mountain fire damage in decades and even since the founding of the People's Republic of China.

The fire has spread to every state in Australia, and New South Wales is the worst affected. At present, there are still more than 65,438+000 fires burning, and more than 3,000 houses are destroyed or damaged.
Several of Australia's largest cities were also affected by the fire, including Melbourne and Sydney. The fire destroyed the houses in the outer suburbs, and thick smoke enveloped the city center.

Australia is a dry country with little rain. Because the terrain is flat, there are no large mountains and hills, and the land is easy to lose moisture under the sun's exposure, so there are many deserts and Gobi in Australia.
In addition, nearly 80% of Australia is eucalyptus, which is very flammable, but not afraid of fire. After the fire, the trunk will germinate again, and the seeds will crack and germinate after the fire, so mountain fires have become the norm in Australia.
In 2009? Black Saturday? This is the deadliest jungle fire in Australia's history, with a total burning area of 465,438+0,000 hectares. However, this year's situation is extremely severe, and the drought has intensified the fire, and the fire fighting work is particularly difficult.
In this fire, more than 7.3 million hectares of forest in six Australian States were burned, which is bigger than Belgium and Denmark combined. The total number of animals affected may be as high as 654.38+0 billion. The carbon dioxide emission caused by fire will directly affect the global climate.
The fire also caused about 650 thousand bats to flood into different cities in Australia, covering the sky, a medical helicopter could not land and children were afraid to go out to school.
When it comes to bats, we have to mention the virus they carry, because our epidemic continues. Bats are the original hosts of many zoonotic viruses, and scientists have found more than 465,438+000 viruses among 200 species of bats. Whether Ebola was discovered in 1976, SARS in 2003, MERS in 20 12, or this epidemic, these viruses are the chief culprit in recent years.
But bats themselves have little chance of causing diseases to human beings, because their living places, habits and feeding habits do not overlap with human beings. It is bamboo rats, civets and even pangolins that cause human infection with the virus. It all comes from our greedy mouths.
We humans once thought that we had stepped onto the top of the biological chain and were top predators. As long as you can eat, you will not let go. On the human dining table, there is not a creature on land, sea and air that is not eaten. In the past, when we often saw a certain country overflowing with creatures, we would say that we in China could eat them to extinction. It's a little arrogant to think about it now.
Throughout the history of human development, we will find that we human beings are actually fighting against nature all the time. Ancient humans sat by a dim bonfire, fearing the predation of large carnivores. For a long time, we have driven the creatures that once threatened us out of human life or kept them in captivity, or even killed them one by one, and countless creatures have become extinct in human hands.
Before we examine our own "victory"? At that time, people thought they had no natural enemies, but the danger was approaching quietly. Plague, smallpox, malaria and the Black Death in history caused billions of deaths. These viruses have caused more casualties than any disaster and war in history, and they have directly changed the history and development process of mankind. The closest one to us was the Spanish flu at the end of World War I, which infected about 654.38+billion people worldwide and killed 25-40 million people (at that time, the world population was about 654.38+700 million people), indirectly leading to the early end of World War I.
So now we are all survivors of evolution, because the virus really paid a heavy price. This may be a natural means of adjustment. Flies, mosquitoes, mice and cockroaches that spread these viruses and are regarded as harmful by us humans still coexist with us. We once threatened to get rid of these creatures, but what happened? Not only do we not have this ability, but we are countered again and again.
At the time of our epidemic, the United States also ushered in one of the worst flu seasons in decades, the 20 19-2020 flu season (from last September to the end of this year 1). In contrast, at least190,000 people in the United States are infected with the flu. The CDC estimates that up to now, about180,000 people have been hospitalized, and it is estimated that100,000 people have died, including 68 children.
In East Africa, millions of desert locusts are rampant, mainly affecting Kenya, Somalia and Ethiopia, and may spread further.
The swarm of locusts is very large, covering the sky and the sun. The largest treaty is 60 kilometers long and 40 kilometers wide, which can cover half of Long Island County in Japan. This is the worst attack on Ethiopia and Somalia in 25 years and the worst attack on Kenya in 70 years.
Desert locusts can eat all the plants they meet wherever they go. These insects with long fingers consume as much food as their weight every day. According to the data of the Food and Agriculture Organization of the United Nations, the locust swarm per square kilometer may include 40 million to 80 million locusts, eating up to 35,000 people's rations.
How many people will go hungry or even be displaced. If locusts are not controlled, they may attack other areas. ...
In recent years, with the rapid development of society and science and technology, the continuous expansion of the living circle has affected the ecological balance. It's really hard to start in 2020. God pressed the pause button for mankind. Mountain fires, bats attacking the city, China epidemic, American flu and locust plague in East Africa, let's stop and think about how to go in the future.
Each of us stayed at home, but we all took part in unprecedented battles.
We humans have reached an unprecedented level in science and technology, and have overcome various problems faced by human survival, but we are still so weak in the face of natural disasters.
Australia is a developed country, and there are large and small mountain fires every year, so the quality, level and equipment of firefighters are beyond doubt. However, modern machinery and fire helicopters can't cope with such a raging fire, just like a gladiator blocking a car and a moth fighting a fire.
Nature has its own perfect regulating system, some of which seem so harmonious. Wild animals and viruses coexist peacefully, and human beings and wild animals enjoy equal rights of survival and resources on the earth. However, if human beings want to destroy this harmonious situation and try to open Pandora's box, they can only suffer the consequences.
Once again, I call on everyone to take care of every animal around us, because they can make us live a good life.
