Recently locust parties from Pakistan have created terror in the fields of India. It has destroyed crops in many states including Rajasthan, Madhya Pradesh and Punjab. In Rajasthan alone, about 90 thousand hectares of crops have been destroyed due to its attack. In view of its increasing attacks, Delhi, Haryana, Himachal Pradesh, Telangana, Odisha and Karnataka have also issued their alerts. Although every year some crops are damaged due to locusts, but in recent times its terror has increased a lot. Now this is the talk of India, but do you know that due to these locusts in the neighboring country China, crores of people died. This incident is about 60 years ago.
In 1958, Mao Jedong (Mao Tse-tung), who was in power of China, started a campaign, which is called 'Four Paste Campaign'. Under this campaign, he ordered to kill four animals (mosquito, fly, rat and sparrow bird). They said that it ruin the crops, due to which all the hard work of the farmers goes waste. Now you must know that finding and killing mosquitoes, flies and mice is a difficult task, because it easily hide anywhere, but the sparrow always likes to live among humans. It got caught in the trap of Mao Jedong's campaign. It was hunted down throughout China, its nests were destroyed. Wherever people saw the sparrow, it used to kill it immediately. The most important thing is that people used to get reward for this too. The number of sparrows who killed a person would be awarded the award on the same basis.
Now the result of killing sparrows in large numbers is that in a few months in China, its number declined sharply and on the other side there was an increase in the wastage of crops. However, in 1960, a famous Chinese ornithologist Sho-shin Cheng told Mao Zedong that sparrows not only waste crops but also eat insects (locusts) that cause large amounts of damage to grains. This was understood by Mao Jedong, because instead of increasing the yield of rice in the country was constantly decreasing. Then on the advice of Sho-Shin Cheng, Mao ordered the sparrow to be killed, with immediate effect, and in his place he ordered the grasshoppers to eat the grains, but by then it was too late. The absence of sparrows had led to a rapid increase in the number of locusts, which resulted in the destruction of all crops. This caused a terrible famine in China and a large number of people fell victim to hunger. It is also believed that about 1.50 crore people died from this hunger. Some figures also show that 1.50-4.50 crore people were killed due to starvation. It is considered one of the greatest tragedies in the history of China.
