Because on today's main program, we talked about how the earth needs darkness just as

much as it needs light.

Everything on earth, us, humans, plants, animals, all of it depends as much on the nighttime

as we do on the daytime and that includes underwater species.

Emily Fobert is a research fellow at the University of Melbourne in Australia and she

studies how humans impact underwater ecosystems, especially when it comes to artificial light.

And her work was inspired by a research trip she took in 2017.

I went to French Polynesia with a colleague and to relatively remote islands, but there's

all these hotels with over water bungalows and lights shining right down on the ridge.

Some of them even have the glass floors and the bungalows with the lights directed onto

the reef below so the tourists can look at the fish at night.

And I've heard that there's impacts of light pollution on a lot of terrestrial animals

and humans for sure.

So just seeing all that light pollution in the marine environment made me realize that

it's something we haven't been looking at, but it's probably an issue there as well.

Back at the lab, Emily decided to see whether light pollution had an impact on a specific

underwater species, clownfish, those orange and white fish that make their homes in

an enemies on coral reefs.

So I had a bunch of clownfish in the lab.

Pan breeding pairs of cornfish, so a female in a male each in their own aquarium, kept
