It is not likely that the amount of trash in the sea would directly affect flooding in Jakarta. Flooding in Jakarta is typically caused by a combination of heavy rainfall, poor drainage, and high tides. While marine pollution can have a range of negative effects on the environment, it is not typically thought to be a direct cause of flooding on land. However, if the trash in the sea were to clog up the drainage systems in Jakarta, it could potentially contribute to flooding. It is important to properly dispose of trash and reduce marine pollution in order to protect the environment and prevent negative impacts on wildlife and human health.
