at this time of year, advent calendars deck the halls around the world.
And the stunning island of Bermuda, some 600 miles east off the coast of the Carolinas, is no exception.
But the island's pink sand beaches share a problem with many coastal regions around the world -- plastic pollution from the ocean is washing up on them.
To highlight the problem, local photographer and visual artist Meredith Andrews is collecting plastic that has washed up on the shores of Bermuda to create a striking advent calendar on Instagram, which she calls an "Adventgram."
Using toothbrushes, lighters, glow sticks, fishing rope and bottle caps, Andrews evokes a powerful yet creative statement about ocean pollution.
"I think about what I have, what I've done the day before, what message I want to express and actually in a way I sort of let the trash guide me," she told CNN.
Andrews picks up all the litter she finds on the beach, but in this project she uses recognizable objects that people can relate to having thrown away.
