China trying to mess with Nature

In 1958, when Mao Zedong the leader of China, decreed that all the sparrows in the country were to be killed, thinking that sparrows ate too much grain and it seemed rational to him for all sparrows to be killed.

People were mobilized to eradicate the birds. They used beating drums to scare the birds from landing, forcing them to fly unitl they died of exhaustion. Poeple killed their shelters, and nests. 

However, when you try to break the law of nature, the nature hits you back. Locsut populations boomed and they ate everything, they ran out of things to eat and millions of starved and died.
