A study by Ehime University revealed that dioxin in the soil adheres to fine particles and flows into rivers. This dioxin is absorbed by aquatic organisms and accumulates in high concentrations through the food chain, posing a serious threat to ecosystems. The study suggests that current environmental standards need to be revised and that countermeasures should be implemented.
2. Ecosystem Changes Due to Deforestation
In Japan, ongoing deforestation is reducing the habitats of wild animals, threatening biodiversity. Deforestation also triggers secondary environmental degradation, such as increased flood risks and soil degradation, which causes significant changes to local ecosystems. This may make it difficult for natural environments to recover.
3. Marine Pollution and Plastic Waste
Plastic waste flowing into the oceans is causing severe harm to marine life. Plastic does not decompose and remains in the sea for long periods, leading to cases where marine organisms mistakenly ingest it, resulting in malnutrition or death. This problem is recognized globally as a serious environmental issue that could lead to the collapse of marine ecosystems.
