În 1978, Seul a început să își arunce tot gunoiul pe o insulă. Ce s-a întâmplat după 15 ani și 92 de milioane de metri cubi de deșeuri mai târziu

Nanjido, once a landfill for Seoul's waste, has transformed into a green space with parks after extensive rehabilitation efforts. The island, which received waste from 1978 to 1993, faced significant environmental challenges, including methane emissions. Following its closure, a stabilization project was initiated, leading to the creation of parks and recreational areas. Despite the successful transformation, underlying issues like methane monitoring persist, highlighting the complexities of land restoration.
