What are the effects of water pollution?

Harm to ecosystems: Pollutants can harm or kill aquatic plants and animals, disrupt food chains, and alter entire ecosystems. 

Health risks: Drinking polluted water can cause serious illnesses due to the presence of bacteria, viruses, and toxic chemicals. 

Contamination of the food chain: Fish and other seafood can become contaminated with pollutants, which then pass to humans when consumed. 

Reduced oxygen levels: Excess nutrients from fertilizers can lead to algal blooms that block sunlight, reduce oxygen, and harm oxygen-breathing organisms like fish.
