Answer: Forestry impacted Seoul in a positive manner by helping it restore to some extent the ecological balance in the region.
Step-by-step explanation: Japan's possession of South Korea had led its forests to be devastated to serve the military purposes of the Japanese Army. This destruction of the forests had started resulting in many environmental issues like soil erosion and extinction of animal and bird species. The concern was taken seriously by the South Korean government and steps to restore the forests started being taken in 1949. The forest in the capital city Seoul was partially restored and it has since then helped bring balance in the regional ecology.
