Light pollution can affect birds that are migrating and use the stars to navigate.
Nocturnal animals sleep during the day and are active at night. Light pollution radically alters their nighttime environment by turning night into day.
Artificial light at night can disrupt that cycle. Our bodies produce the hormone melatonin in response to circadian rhythm.Nighttime exposure to artificial light suppresses melatonin production.
