Explanation
Globally, 90% of wastewater returns to the environment untreated. This untreated wastewater, which includes industrial, agricultural, and household waste, leads to widespread pollution of rivers, lakes, and oceans, posing serious risks to ecosystems, human health, and water quality. The lack of proper wastewater treatment is especially prevalent in developing regions, where infrastructure and resources for waste management are often limited. Effective wastewater management and treatment are crucial for protecting water resources and supporting sustainability goals, such as those outlined in the United Nations Sustainable Development Goals (SDGs).
