What is one major environmental concern related to Lake Ontario?

• A. Excessive salinity levels
• B. Accumulation of plastic debris
• C. Pollution runoff
• D. Overfishing

Answer: (C)

The accumulation of pollution runoff is a significant environmental concern related to Lake Ontario due to its impact on water quality and ecosystem health. Runoff often contains fertilizers, pesticides, and heavy metals from agricultural and urban areas, which can lead to harmful algal blooms and toxicity in aquatic life. These contaminants can degrade habitats, harm fish populations, and affect drinking water for communities that rely on the lake. Effective management of runoff is crucial for preserving the natural environment and ensuring the sustainability of the lake's resources. While excessive salinity levels are not a primary issue for Lake Ontario, plastic debris is a growing concern in many bodies of water, and overfishing poses challenges to fish populations, these specific issues are not as prominent or immediate as the problem of pollution runoff in this context.
