Final answer:
The visitors plan to use drone technology for 24-hour monitoring to address human incursions, and they might implement water filtration systems or clean-up projects to fix the brown, muddy water at Nyas' village.
Step-by-step explanation:
To address the issue of brown, muddy water at Nyas' village, Isla and others have discussed the need for better 24-hour monitoring to protect the area. One of the proposed solutions involves using drone technology for surveillance. Drones can provide a continuous aerial view, allowing for quick detection and response to any unauthorized human activities that could further pollute the water. In addition, to fix the contaminated water itself, the visitors might look into setting up water filtration systems or initiating a clean-up project to remove any existing pollutants from the water source.
