You are right, light pollution is a problem, it has negative impact for the nature, mostly animals active at night. I do love to watch the stars as well. It's better though when we can limit the energy which we use but still have the access to it, so I don't think blackouts are the solution :)

Yes, from my childhood I do remember short blackouts and as the child I have mostly positive memories related to it - usually we were playing the board games with the parents or sitting together with the candles and talking. Even though it's sentimental and in some point romantic as well, it has very negative impact for the economy, quality of life, education, like you mentioned and many other areas.

Thank you for your great comment. Have a good day!
