He was the first black President of South Africa, he spent 27 years for trying to overthrow the pro-apartheid government. After he got out of prison, he worked to achieve human rights and a better place for the people of South Africa.

Because, if people are secure and have liberty but government is not doing anything about that. people are not survive and it will lead to disruption.
I believe the best answers are: humans moved out of Africa, and h<span>umans learned how to control fire
But i'm not sure since there are not any options available</span>
Since Adam Smith was an ecologist I would go with #1.
Government should interfere as little as possible in the economy.
