Summary
Luminescent bone-eating worms, giant squid and a sea cucumber commonly known as the headless chicken monster: some extraordinary creatures live at the bottom of the sea. For a long time almost everyone agreed the pressure was too intense for any life to exist. Now, it seems, the more we look the more new species we find. But, many fear, marine life would be threatened if plans to extract precious metals from the potato-sized metallic nodules that grow on the seabed are allowed to go ahead.
Metals such as copper, manganese and cobalt are in high demand in the manufacture of mobile phones and renewable energy technologies, such as batteries for electric cars, wind turbines and solar panels. Deep sea mining companies argue that we will need these metals to create a carbon Net Zero economy. Meantime, the World Wildlife Fund is pushing for a moratorium on deep sea mining. And several companies agree: including Google, BMW, Volvo and Samsung. Do we need to choose between green and blue? Or is there a third way that protects both the planet and all the riches in our oceans?
Marine biologist, Helen Scales talks to Jim Al-Khalili about her life and work: fish watching off an atoll in the South China Sea to assess the extinction risks to the Humphead Wrasse and a research expedition to explore the brilliant abyss. And she warns of the environmental devastation that could be caused if plans to mine the metals on the bottom of the ocean were to be allowed to go ahead.

| 0:46.0 | where I get to talk to amazing men and women who are trying to understand our world and make |
| 0:50.9 | it a better place. Today's interview is all about the ocean. It's been said before but I'm going |
| 0:56.1 | to say it again, we know more about the surface of the moon than we do about the deep oceans |
| 1:01.2 | of the earth. But Helen Scales has opened my eyes to the rich diversity of marine life, |
| 1:07.6 | luminescent, boniting worms and a sea cucumber known as the headless chicken monster. The more |
| 1:13.6 | we look the more weird creatures we find living in the deep ocean. It's a golden age of exploration |
| 1:19.1 | of the ocean abyss but sadly all too often exploration leads to exploitation and Helen is |
| 1:25.5 | very concerned about plans for deep sea mining. She learnt to dive in a swimming pool in Surrey |
| 1:31.6 | and has spent much of her life watching fish. In particular the humphead rass, an enormous coral |
| 1:38.0 | reef fish that some call the tiger of the sea and recently she was lucky enough to join an expedition |
