Welcome to Litsy!

I found this very interesting. He not only discussed the light or darkness of each place, and the resulting lack of stars that can be seen, he also talked about crime (some light helps, but more and more light doesn‘t make a difference), and also the effect of perpetual light at night on humans‘ health, not just due to sleepyness for those who work at night, but also cancer. There was discussion of other animals, who rely on night and darkness.

The link between artificial light and cancer (continued)

The link between artificial light and cancer (part 1 of 2).

Light pollution isn't just something that annoys astronomers. Artificial light is directly linked to certain types of hormonal cancers like breast and prostate cancer, and has terrible effects on our ecosystem and the planet due to the various types of damage that it causes to nocturnal animals. Paul Bogard explores these issues masterfully in this important book.

I took this picture last night, just love the gentle glow of the lights.
Wishing everyone a wonderful holiday season!! Sending a lot of bookish love to each one 😊 💕💕📚📚🎁🎁
