polluted water fish 3d model

A realistic 3D model of a dirty water river with dark, murky, contaminated water. The river should have floating trash such as plastic bottles, plastic bags, cans, and scattered debris. Include several dead fish floating on the surface or near the riverbank. Add oil slicks, foam patches, and muddy, eroded riverbanks to show severe pollution. The entire environment should look unhealthy, dirty, and heavily polluted
