Which of the following is a potential environmental issue caused by snowmobiles?

Noise pollution is a significant environmental issue caused by snowmobiles. These vehicles often operate at high noise levels, which can disturb wildlife and negatively impact their natural behaviors, such as mating, feeding, and nesting. High levels of noise can also disrupt the recreational experience of other people in natural areas, detracting from the tranquility that many seek in outdoor spaces. The cumulative effect of noise from multiple snowmobiles can create a challenging soundscape in environments that are usually quiet, affecting both human enjoyment and wildlife health.

Other options, while they may sound relevant, do not specifically pertain to the environmental impacts commonly discussed with snowmobiling. For instance, damage from snowmobile lights is less of a direct concern compared to noise, and while water contamination and air conditioning disturbances may be environmental issues in broader contexts, they are not typically associated with snowmobiles in the same way that noise pollution is.
