What is a potential consequence of storm water drains leading directly to natural waterways?

1. Better irrigation systems for plants

2. Harm to fish, plants, and other living things

3. Improved water quality

4. Increased recreational water activities

The correct answer is: Harm to fish, plants, and other living things

Storm water drains leading directly to natural waterways can introduce various pollutants, including sediment, chemicals, and debris, into these ecosystems. The runoff often contains harmful substances from urban areas, such as oil, heavy metals, pesticides, and nutrients from fertilizers. These pollutants can disrupt the delicate balance of aquatic environments, leading to harmful algal blooms, decreased oxygen levels, and toxic conditions that can be detrimental to fish, aquatic plants, and other living organisms. Additionally, the increased flow of stormwater can result in erosion of riverbanks and sedimentation in waterways, further harming habitats. This can lead to a decline in biodiversity and health of aquatic communities. The overall impact is that the health of the ecosystem is compromised, making this potential consequence particularly serious and highlighting the importance of managing stormwater properly to protect natural waterways.
