23 Oct 2018 - BBC NEWS - Doyinsola Ogunye, along with around 20 volunteer children, vigorously combs a sandy shore in the Nigerian coastal city of Lagos, unearthing deeply embedded litter and plastic that can prove deadly to sea turtles.
The tide is low and the layer of scattered debris across a seemingly endless stretch of golden sand emerges as the waves recede into the ocean.
Every type of man-made waste imaginable, from polystyrene, broken ceramic, assorted flip-flops and building materials, is visible. I can even spot a syringe.
This is Elegushi beach - and nothing can beat the beauty this strip of Atlantic coastline, but the sheer scale of litter hits you right away.
"Sometimes it gets very overwhelming," says Ms Ogunye, an environmental activist who has set up a programme to rid the beach of rubbish.
'A bath for the beach'
Every week she and her volunteer crew collect about 50 large sacks of litter.
It's a mammoth task, but the 30-year-old has put herself on the frontline, battling the destruction caused by pollution.
