BBC CrowdScience listener Dinesh, an organic farmer in India’s Tamil Nadu province, thinks earthworms are underrated. He got in touch with CrowdScience to ask them to explore earthworms, and whether they could play a bigger role in the future of organic farming.

Presenter Anand Jagatia dons his gardening gloves and digs the dirt on these remarkable creatures, discovering how they can help improve soil quality, prevent fields from becoming waterlogged and improve microbial numbers, all of which has the potential to increase crop yield.

But he also investigates the socalled "earthworm dilemma" and the idea that in some parts of the world, boreal forest worms are releasing carbon back into the atmosphere, which could have dangerous consequences for climate change.
