In this short talk, Sky Island Alliance staff discuss how artificial lighting threatens the region’s spectacular dark skies, as well as the diversity of life here that needs the dark to thrive. We also explain how you can step outside after the webinar and collect a simple measurement of how dark the sky is above you.
By sharing your observation with the Globe at Night project, you can help us document where the best dark-sky habitat is today. And you can help power a campaign to stop border wall lighting from disrupting the night. This webinar is presented in English and Spanish.
