The sea turtles are the turtle which lives in water. when mature female turtles are ready to lay eggs, they come over to the sandy shore and find a dark place to lay their eggs they dig a shallow hole in the sand and bury eggs there and return. Artificial lighting on marine turtle nesting beaches disturbance in the ability of hatchlings to find the sea from their nest. Artificial lighting causes thousands of hatchling deaths each year. Ports, ships and industrial facilities such as oil rigs can increase the footprint of artificial light sources. Any light source producing light that is visible from the beach is likely to cause problems for nesting sea turtles and their hatchlings.
How does light pollution affect humans and animals?
Light pollution radically alters their nighttime environment by turning night into day. Too much light can harm our eyes and also the harm the hormones such as melatonin that does this job impact of light. Artificial lights disrupt this nocturnal activity, interfering with reproduction and reducing populations Artificial Lights Disrupt the World’s Ecosystems. Nocturnal animals sleep during the day and are active at night. This affects the environment, energy resources, wildlife, humans, and astronomy research. This is unwanted light from the artificial sources does negatively impact the people, for example, people trying to sleep in areas exposed to a lot of light pollution will find it more difficult. This light pollution creates so much artificial light that it practically tricks your brain into thinking that it is still daytime, disrupting your body circadian rhythm. Not only does light pollution affect people it also changes the behavior of animals and insects.
Ways to reduce light pollution:
- Check with your power company to see if you are paying for outdoor lighting.
- Start with the light switch
- Place motion sensors on essential outdoor lamps.
- Replacing conventional high-energy bulbs with efficient outdoor CFLs and LED floodlights.
- Consider replacing outdoor lights with intelligently designed, low-glare fixtures.
- Use less light.
- Use automatic timers to put off the street light at a pre-scheduled time.
- Useless decorative lighting.
- Stay informed about light pollution.
- Take preventive measures wherever possible.
- Avoid light trespassing.
Solutions to light pollution affecting sea turtles:
- Switch off the unimportant lighting avoid decorative lighting in areas that are visible from the beach and remove permanently, disable or turn off fixtures that cannot be modified in any other way.
- There are ways that beach front property owners can modify their lights to prevent them from being seen from the beach.
- The goal of any program to reduce sea turtle harassment and mortality caused by lighting is to manage light so that it performs the necessary function without reaching the nesting beach.
- Light sockets with exposing light source like light bulbs, should be replaced with fixtures that are specially made to recess or the light source should be shielded.
- Plant to improve vegetation buffers such as sea grapes and other native beach vegetation between the light
source and the beach to screen light from the beach.
- Use shielded motion detector lights for lighting, and set them in the shortest time setting.
- Replace fixtures that scatter light in all directions such as globe lights or carriage lights with directional fixtures
that point down and away from the beach.
