How would disposal of garbage affect the living organisms in the river?

Disposal of garbage in a river can severely impact living organisms by introducing harmful pollutants, reducing water quality, and depleting oxygen levels. Toxic substances from waste can contaminate the water, harming aquatic life and disrupting ecosystems. Additionally, physical debris can cause injury to animals and block sunlight needed for photosynthesis, further destabilizing the habitat. Overall, such pollution can lead to a decline in biodiversity and the health of the river ecosystem.
