noise pollution

The campaign group is also claiming the planning process failed to properly factor in additional noise pollution and impact on air quality.

The animals are increasingly stressed from changes in food availability, shipping traffic, noise pollution, waste discharge, disease and plastic debris, and their ability to avoid and survive these impediments is diminishing.

"However, from a legal point, the noise pollution laws are usually used by residents rather than businesses so that is an issue for us."

This is said to produce a form of underwater noise pollution which distresses the animals.

Researchers at the University of Glasgow said possible causes include chemical, plastic and noise pollution and accidental entanglements in fishing gear.
