In Earth's climate system, positive feedback's tend to amplify changes in the system, and negative feedback's tend to encourage the system against change. Having a positive feedback gives the newest updates and brings the problems on the table, thus changes are always a must when there's proof that suggest there's big problem, but when the feedback is negative, lacking, then there's not pressure for changes, so anyone who has interest in not changing will push for that, thus encouragement of taking no changes. <span />
Answer:
The cause was the command type of economy and the result was famine and millions of deaths.
Explanation:
The communist governments in East Asia, like all communist countries, had command economies. This meant that everything in the economy is planned and regulated by the government. This was also the case with agriculture, where government officials were making a plan on how much and what should be produced. The plans were often made in the manner that it should be produced as much as society needs.
Because agriculture is heavily dependent on weather conditions, as well as the impact of pests, even the slightest disturbance meant that there won't be enough food, and if it was a bigger disturbance then a big portion of the population would have experienced a famine. This has happened on numerous occasions, with the small amount of food being forcefully transported to the cities, while the rural population that produced it was left without anything for eating. The end result has been tens of millions of deaths because of starvation, based on terrible politics.
Because it was a very unexpected event and they didnt have the tech to forecast it
