A more sustainable future lies within reach. One where human societies are powered by wind and solar energy, leaving behind dirty, climate-changing fossil fuels in the past. Sounds good right?

But with many tonnes of rare earth metals needed to manufacture just one wind turbine, switching to this greener way of life likely means more mining – and lots of it – at least in the short term. But where and how could we get these metals while causing the least possible harm to people and planet?

Khalil meets scientists and campaigners to find out:

• Why are some people so interested in mining the deep sea?
• What lives on the ocean floor and what would happen to it if mining got the green light?
• How can science help reverse the long-term damage caused by mining?

• Louisa Casson, Global Project Leader for Greenpeace's Stop Deep Sea Mining campaign
