From 1958 to 1962 China killed insane amount of sparrows which lead to the Great Famine.

Mao Zedong

From 1958 to 1962 the genius above gave an order called  the Four Pests Campaign part of a group of plans to help his peons in his country move forward. The four pests to be eliminated were rats, flies, mosquitoes, and sparrows. I’m all for eliminating flies but sparrows really buddy ?  So his slaves started killing sparrows by the millions.  What did the sparrows ever do to hurt anyone ?  Apparently they ate grain  planted in the fields and this affected their food output.

 

 

So less grain eaten by sparrows and crop production increased exponentially.  NOT !  since they started killing sparrows by the shitload another problem arises.  Locust started eating all their crops like crazy. They ate so much crop product that it started the great famine that ended killing about 45 million Chinese.  Things got ugly people started eating each other started eating rats. They would kill people to eat them. Some crazy parents would kill and eat their own children.

Eventually they figured out that the sparrows would eat locust and keep the population in check so the crops would grow.  That was Mao’s bad  so he then changed the campaign to kill  rats, flies, mosquitoes, and bedbugs.  It’s crazy how one species taken out of the food chain can affect things so bad.  Some of the people that died were kept hidden from the government so families or friends could continue collecting their ration of food.  The bodies would just start rotting away and hungry people would have to fight rats to eat the decomposing corpses.  Eww that shit is gross but you got to do what you got to do.
