Dr. John Barentine FRAS<p>“We used a stratified survey to explore the impact of residing in regions with different sky brightness levels on the perception of anthropogenic light. Brightness levels were perceived as satisfactory, despite most recognising negative impacts. Respondents who lived or grew up in high-sky brightness regions were more likely to feel unsafe and to perceive anthropogenic light as beneficial for nature and health. Support for technological mitigation measures and awareness campaigns was high, but support for shorter illumination time was higher in areas with lower sky brightness.” </p><p><a href="https://www.sciencedirect.com/science/article/pii/S0169204625001537" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">sciencedirect.com/science/arti</span><span class="invisible">cle/pii/S0169204625001537</span></a></p><p><a href="https://astrodon.social/tags/LightPollution" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LightPollution</span></a> <a href="https://astrodon.social/tags/DarkSkies" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>DarkSkies</span></a> <a href="https://astrodon.social/tags/ALAN" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ALAN</span></a></p>
