Excerpt: "But light pollution can also be a hazard to our health. Just about every organism on the planet lives its life according to the rhythms of daytime and darkness. Excessive light can disrupt an animal's migratory, hunting, breeding and sleep cycles. And several human health problems — from chronic fatigue and migraines to sexual dysfunction — have also been linked to high-levels of light exposure."
There's beauty in the night sky, and according to Joy Cardin's guest, we could enjoy it more and save energy if we reduce light pollution.
