Japan is experiencing a decline in its rural population, which is leading to unexpected consequences for wildlife. Researchers have found that instead of a resurgence of wildlife in abandoned farms, there is a decline in biodiversity. A 2025 study revealed that areas with decreasing populations saw significant drops in species such as butterflies and frogs. This phenomenon is not unique to Japan, as similar trends are observed globally, indicating that the loss of human-managed landscapes can negatively impact biodiversity.
