Final answer:
The river in Jakarta, Indonesia, is heavily polluted due to poor sanitation practices, rapid urbanization, and increased pollution as a result of industrial waste. This pollution poses serious ecological and health risks.
Step-by-step explanation:
The river in Jakarta, Indonesia is experiencing significant water pollution, which negatively impacts both the ecology and the health of local communities. Jakarta is grappling with the challenges of rapid urbanization and a growing population, which has led to increased demand for natural resources and heightened pollution levels. The city's rivers, often used for waste disposal, suffer from the poor sanitation practices prevalent in areas with limited clean water and economic resources.
Furthermore, the geographic location of Jakarta on the coast of Java means it is susceptible to problems faced by many densely populated coastal cities, including overcrowding and insufficient infrastructure to support its inhabitants. As the city expands, more strain is being put on existing systems, leading to exacerbated environmental issues. These include rivers becoming dumping grounds for industrial waste, leading to the deterioration of water quality and loss of marine life, and posing severe health risks to populations that rely on these water resources.
