The rulers of the west african kingdoms expanded their lands by a. conquering surrounding kingdoms b. deforesting surrounding areas c. making treaties with neighboring kingdoms d. expanding their boundaries into the sahara desert

The correct answer is option A. "conquering surrounding kingdoms".

Explanation:

The three more important kingdoms of West African were the kingdoms of Ghana, Mali, and Songhai. These three kingdoms dealt with independent rival kingdoms by conquering them and taking their lands and control over trade routes. Usually, West African kingdoms expanded by conquering surrounding kingdoms. For instance, the Mali Empire became one of the largest by defeating nearby kingdoms, including the empire of Ghana.

this statement is true.

forests are public goods, available for everybody. when usage of such a good becomes interesting for consumers and its usage increases, there can be a risk of overexploitation. it is a non rival good therefore, if one person consumes the good it does not reduce the availability for subsequent consumers.

these caracteristics require the establishment of measures in order to prevent the destruction of a commonly owned space, for example, to restrict the amount of people that have access to the same time.
