What you can learn from elephant poo?
There's a big meeting of world leaders happening in South Africa, where they're trying to find ways to help the world's elephant population and other threatened wildlife.
Jenny went to look for wild African elephants on a reserve in the north-east of South Africa with a specially trained ranger.
It might be a bit smelly, but she found out there's a lot you can learn about elephants from their poo, like what they've been eating.
Remember, you mustn't ever touch animal poo - this ranger is specially trained and knows how to do it safely.
