What should be done to ensure that waterways remain disease-free?

To ensure that waterways remain disease-free, proper disposal of waste is crucial. When waste is not disposed of correctly, it can lead to contamination of water bodies, which can harbor harmful pathogens and pollutants. This contamination can affect not only aquatic life but also human health, as people who come into contact with or consume contaminated water can suffer from various illnesses.

Proper waste management includes using designated facilities for dumping sewage and garbage, which helps maintain the cleanliness and safety of the water. Other options may seem beneficial for outdoor recreation or community development, but they do not directly address the health of the waterways. Using more watercraft or increasing the number of boats, for instance, can contribute to pollution rather than mitigate it. Thus, ensuring that waste is disposed of properly is fundamental in safeguarding the health of water ecosystems and the people who rely on them.
