Denmark Municipality Installs Red Streetlights to Protect Bats

Denmark Municipality Installs Red Streetlights to Protect Bats

A small area near Copenhagen, Denmark, is changing its streetlights from white to red to help bats.

Some bats don't like bright white lights because they can change how the bats behave and make them more likely to be eaten by predators.

Scientists have found that red lights don't bother bats as much.

This is important because bats help the environment by spreading seeds, pollinating plants, and eating harmful insects.

Other places, like a county in the UK, have also used red lights to protect bats.

Changing the lights helps keep the bats healthy and safe.
