Final answer:
Excessive noises caused by PWCs can harm marine life, impact water quality, and disturb other boaters.
Step-by-step explanation:
When it comes to excessive noises that personal watercrafts (PWCs) can create, there are several things to be aware of:
- The potential harm it can cause to marine life: Excessive noise can disrupt the normal behaviors and communication of marine animals, affecting their ability to find food, navigate, and communicate with each other.
- The impact it can have on water quality: PWCs can stir up sediments and disturb the bottom of the water body, potentially releasing pollutants and affecting the clarity and quality of the water.
- The disturbance it can cause to other boaters: The loud noises produced by PWCs can be disruptive and annoying to other boaters, affecting their enjoyment of the water and potentially creating conflicts.
Therefore, the correct answer is 4) All of the above.
