b. Give two reasons why this occurs.
c. Give two ways you can reduce the possibility of this occurring.

i do believe that the correct answer is   (technical reasoning); luck

explanation:

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.
