Science can answer most of life’s big and little questions – but you don’t always have scientist on hand to explain their reasoning. Now you do, with a new Cosmos Science Detectives podcast finding the experts and interrogating them to help answer your burning inquiries.

The crack Cosmos team of newsroom science journalists will leave no stone unturned. They’ll open a case file; find evidence and witnesses; and give you the detail you need to close a case of “uncertainty.”

In this episode, they explain why mangroves are thought to be important.
