What is one effect of water pollution?

• A. It can enhance aquatic ecosystems
• B. It can reduce global warming effects
• C. It can cause harm to aquatic life and pose health risks to humans
• D. It can increase the oxygen levels in water bodies

Answer: (C)

One significant effect of water pollution is its ability to cause harm to aquatic life and pose health risks to humans. Pollutants, such as heavy metals, chemicals, and pathogens, can enter water bodies through industrial discharges, agricultural runoff, and sewage. These contaminants can disrupt the sensitive balance of aquatic ecosystems, leading to the death of fish and other organisms, loss of biodiversity, and degradation of habitat. Additionally, when humans consume contaminated water or fish, they can experience health issues ranging from gastrointestinal diseases to long-term health problems, such as cancer. This underscores the critical importance of maintaining water quality for both environmental health and human safety.
