How light pollution affects wildlife?

Light pollution makes it harder for animals to see the night sky, which can mess up their daily routines and even hurt them.

Imagine you're playing hide-and-seek at night. You need the moon or stars to help you find your friends. But if someone turns on a really bright light all around you, you can't see anything, it's like playing in a giant flashlight! That’s what happens to wildlife when there is too much light pollution.

How animals use the night

Some animals, like bats, use the dark to find their food. If the sky is too bright, they might not be able to see well enough to catch insects. Nocturnal animals, those who are awake at night, rely on darkness to move around safely.

What happens when there’s too much light

Light pollution can also confuse animals that use the stars for directions, like sea turtles. When baby sea turtles hatch, they usually head toward the ocean using the moonlight. But if there's a bright city nearby, they might get confused and go in the wrong direction, straight into traffic or away from water!

So, too much light can mess up animals’ lives just like it messes up your game of hide-and-seek.
