Sensory Pollution
Noise, light, and chemicals are pollutants that can impact the senses of wildlife. Data centers are large sources of light and noise pollution in particular. Miguel Yanez-Barnuevo provides a good overview of the noise produced by data centers. This annotated bibliography looks as the science of how sensory pollutants impacts wildlife.
In this review article, Dominoni et al. (2020) discuss the direct and indirect impacts of noise, light, and chemical pollution on the behavior and physiology of wildlife. All three are types of sensory pollution produced by data centers. Particularly relevant to the Franklin County data center fight are the impacts of noise on bat foraging and chemical pollution on mating success in male newts. The authors provide this framework for thinking about the effects of sensory pollution. 1.) Masking - the sensory pollutant interact with the ability of an animal to detect their target stimuli. Think, noise preventing bird unable to hear the cat hunting it. 2.) Misleading - a sensory pollutant is detected as a natural cue by the animal and provokes an inappropriate, often harmful, response. Think moths and other nocturnal insects attracted to bright lights. 3.) Distraction - the sensory pollutant interferes with an animal's ability to process information because the pollutant occupies part of the animal's brain capacity. Think, that jackhammering is making it hard to concentrate on my work.
The authors look at data collected by citizen scientists across the US to understand the impacts of noise and light pollution on bird reproductive success across 142 species. They divided bird species into those that live in forests and those that live in more open habitats, like grasslands. Noise had a particularly negative impact on forest birds, with higher noise levels resulting in smaller clutch sizes, more failed clutches, and reduced nest success. With increased light exposure, birds of both habitats laid eggs earlier in the year. Data centers are lit beacons, both during and after the construction phase.
This is a meta-study that compiles studies examining the impact of man-made noise across all type of animals. The work is highly technical with sophisticated statistical analysis of dozens of studies. The take home message is that man-made noise has a negative impact on animals across the Animal Kingdom and that this pattern is caused by "the majority of species responding to noise rather than just a few species being particularly sensitive", The supplemental spreadsheet provided is an excellent resource for studies on specific animals.
