Sea Turtle ARE Endangered

• Our city lights in Florida has impacted sea turtle nesting habits.

• High Tide Occur during Spring Tides when the moon is full.

• Sea Turtles have adjusted breeding to the full moon light to lay eggs further up the coast for the eggs’ protection.

• If you don’t know during full moons, it’s brighter.

Light has harmed Sea Turtles

• Sea Turtle adjusted their breeding cycle to the moonlight

• But city lights suggest Sea Turtles to breed all the time even during neap tide

The wrong time is neap tide.

• During neap tide turtles lay eggs closer to the shoreline

• When High Tide swings by the eggs and snatch them into the ocean.

• It’s game over
