Scientists say we need to save the world’s seabirds – because their poop could be worth millions.

Researchers say the droppings left by seagulls, penguins, and pelicans – known as guano – makes a great commercial fertilizer, potentially worth over half a billion dollars each year.

The guano is also vital to marine ecosystems. All the more reason, scientists say, that seabird habitats must be preserved.

Did you have any idea there was so much money in poop?
