Well, for the great leap forward, got say that Mao has good intentions, he wanted china to grow strong. But like I said the guy know squat about science and economy. so although his intentions are good, but his actions had the complete opposite effect. He wanted make quality steel out of daily cookware that peasan's use, well, he ended up with loads of scrap steel and people are short on cooking ware. And he qualified mouse, fly, mosquitos and that little brown bird (don't know the birds name in english) as the enemy of people that has to be eliminated. Well, mouse, fly and mosquitos is pretty straight forward, but he had to add the little brown bird. his reasoning was the bird always come steal rice from peasant at harvest time. What he failed to acknowledge is the bird is also the natural enemy of grasshopper. As he made himself like a god to the peasans, when he urged the people go out and kill those 4 animals, the peasans did a damn good job, they practically eliminated all the bird, and the grasshoppers dont have their natural enemy anymore and they multiplied like made then caused the major unnatural disaster ended up with millions died of starving.
