If the people of DRC were to use the minerals they mine to manufacture things and then export them, they would earn more money. Why do you think they export minerals ?

Because of LACK OF INFRASTRUCTURES

Explanation:

Despite the fact that Democratic Republic of Congo, DRC having various mineral resources such as cobalt, copper, diamond, tantalum, tin, and gold, they chose to export it instead of manufacturing it, because they lack the necessary infrastructures and expertise to refined the minerals to final products.

Also, due to invasion from neighboring countries' soldiers such as Burundi, Uganda and Rwanda, in 1998, who stole the mineral resources of DRC, and destroy their infrastructures, this led the country to export the few minerals after the invasion because its rural infrastructure was destroyed and mining outputs waned.

Hence, DRC chose to export their mineral resources instead of manufacturing it to final products, Because of LACK OF INFRASTRUCTURES to refine it.

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.
