Visual pollution affects some creatures


When sea turtles start their journey (from their nests), they need some light (oriented in sea/ocean). If resorts emit light, they would go against sea/ocean. If this happen they die because of the fact that they never reach sea/ocean.

Nocturnal animals rest by sleeping during the day and become active at night. Light pollution radically alters their nighttime environment by turning night into day (International Dark Sky Association, 2017).

According to research scientist Christopher Kyba, for nocturnal animals, “the introduction of artificial light probably represents the most drastic change human beings have made to their environment.” (International Dark Sky Association, 2017).

“Predators use light to hunt, and prey species use darkness as cover,” Kyba explains “Near cities, cloudy skies are now hundreds, or even thousands of times brighter than they were 200 years ago. We are only beginning to learn what a drastic effect this has had on nocturnal ecology.” (International Dark Sky Association, 2017).

Glare from artificial lights can also impact wetland habitats that are home to amphibians such as frogs and toads, whose nighttime croaking is part of the breeding ritual. Artificial lights disrupt this nocturnal activity, interfering with reproduction and reducing populations (International Dark Sky Association, 2017).
