A ban on commercial hunting for whales came into force 40 years ago. Tom Heap and Helen Czerski look back on the whaling industry with one of the last of Shetland's whalers and ask if our largest mammals have bounced back from the extinction that so many species were close to reaching.

They're joined by Jayne Pierce of the South Georgia Heritage Trust, the marine biologist and author of Eat, Poop, Die, Joe Roman and by linguist Inbal Arnon. Joe talks about his latest study for Whale and Dolphin Conservation which reveals the importance of whales in moving nutrients around the ocean while Inbal talks about her work comparing how whales and human babies learn to communicate. Jayne discusses this weekend's festival in Dundee which commemorates Scotland's role in the whaling industry and marks the launch of the Whaler's Memory Bank, a project to capture the voices of the last of the men who spent the British winter in the Antarctic capturing and processing the whales that found their way into our margarines and military hardware until the 1960s.
