WebAnswer (1 of 2): Tropical forests pretty much provide no advantage to your nation. Before In 2020, the Amazon hit the highest rates on record, and it is predicted that, at the current rate of deforestation, we will reach the Amazons tipping point by 2030. These land use changes are made under the false pretense that they will benefit local communities with jobs and drive economic growth.Wealthy nations drive demand for tropical timber, and cash-strapped governments often grant logging concessions at a fraction of the lands true volume, National Geographic explains. Many restoration projects focus on individual sites, and dont take the surrounding areas or the ways they are used, managed and accessed by local stakeholders sufficiently into account. 205-233, Foreign Policy, No. ; Gamma, A.; Liechti, M.; Huber, T.
