power-elite model

Explanation:

The power elite model is extremely similar to the oligarchy system. But the 'select few' that have the power in society does not have to necessarily a Nobel.

For example, units States is a power elite model even though we don't have a group that we consider as 'nobles here'. But when you clearly examine its power structure, you will realize that the control over the country falls to a small group of people such as military leaders, corporate owners, high ranking government officials and their family, etc

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.
