Light pollution and hatchlings sea turtles
Sea turtles live 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, burry the
eggs there, and return to the ocean.
Florida beaches in the USA are known for their high sea turtle population.
After incubating for about two months, the eggs are
hatched, and the hatchlings turtles stay beneath the
sand until the temperatures and conditions are right to
With the right conditions, they wave their way onto the
surface in the night, and move to the ocean with the help
of natural lights reflecting on the sea. Baby sea turtles
naturally move towards moonlight reflection in the hope of
getting into the ocean.
Unfortunately, our beaches are full of artificial lights from
beach houses, car parks and security lights. As a result,
the baby sea turtles are deceived, and move towards
these artificial lights. Many of them are harmed and killed
before they find their way to the ocean.
Egg laden turtles need dark quiet sandy beaches to lay their eggs, just as the hatchlings also depend
on natural skylights to giude them to the waters. There are bound to be disorientations when we flood
our beaches and nearby living areas with bright artificial lights.
