A large number of grasshoppers invading the world, explaining in a movie 'What is different from the past in 2020?'



It is

reported that grasshoppers, which occurred in large numbers around Africa in 2019, are rushing to Asia while expanding in scale. The grasshopper, which has been plagued by humans in the past many times, explains in detail how YouTube channel Vox, which deals with social issues, discusses the mechanism that is occurring in unprecedented scale.

Why locusts are descending on East Africa-YouTube


The origin of the event was a cyclone that hit the Arabian Peninsula in May 2018.



As a result, the southern part of the Arabian Peninsula was filled with water for the first time in 20 years, and countless lakes were created in the

Rub Al Khali Desert.



Furthermore, a cyclone occurred in October of the same year.



Subsequent large-scale cyclones occurred in the Arabian Sea at an unprecedented frequency, and many arid regions were hit by record floods.



That was true for regions such as Somalia in eastern Africa.



Eventually the water drained, but instead a new disaster occurred. That is '

gut '.



The brute damage is caused by an insect, the

locust locust .



The locust locust habitat spans Africa, the Middle East, and Asia and is very widespread.



Although it is a locust locust that frequently causes enormous damage, it usually lives not as a herd but as a unit, and this condition is called

loneliness .



However, when sudden rain causes vegetation to grow lush and many individuals gather in one place, an accident occurs.



First, the body color changes to yellow or black, which makes it smaller and optimized for flight.



In addition, your brain will change and your appetite will increase.



This state is called the

colony fauna, and the generation of individuals in the flora fauna from the solitary squirrel grasshopper is called phase mutation .



In this state, the locust grasshopper lays a large number of eggs, and the larvae that evade the eggs form a group called 'hopper band'. Larvae do not have wings, so they only bounce around the ground, but once wings grow and gain flight ability, it becomes impossible to stop them.



The herd is now crowded with up to 150 million locust locusts per square kilometer, and the herd can travel 150 km a day on the wind.



A single locust locust eats as much plant as it weighs each day, so in a large flock, it eats up as much food as 3500 humans.



From the latter half of 2019, the worst

bruises in recent decades have occurred in East Africa, but in 2020, a larger herd of 2,400 square kilometers has started to occur.



This flock is three times the size of New York City and has the power to consume tens of millions of food in a short time.



As soon as it was affected, the plane had to change routes.



In Ethiopia, 50,000 acres of farmland have been destroyed...



Many people are facing serious food shortages.



Also, the range of damage is expanding. In February, the Pakistani government issued a declaration of an emergency due to slaughter...



At the end of May, a swarm of mackerel locusts reached northern India, east of Pakistan, causing the worst damage to the region since 1962.



The answer to the question, 'Why is there more grasshoppers in 2020?' is 'climate.' The number of mackerel locusts increases by 20 times with each generation due to climatic conditions suitable for breeding.



In particular, populations will grow exponentially when there is a large amount of rainfall over a long period in an arid region.



In other words, the cyclones that frequently occurred in the Arabian Peninsula and eastern Africa from 2018 to 2019 triggered the record-breaking outbreak of Sabactivata.



In the past, cyclones were not common in the Middle East and East Africa, but they are becoming a common phenomenon due to climate change.



'The impact of climate change isn't as simple as'green in rain when it rains in the desert,' but it's bounced back to humanity in the form of a food crisis caused by floods and massive locust locusts,' Vox concludes. I am.
