Episode description
The pandemic showed Africa at the back of the global queue when it came to vaccines. That should never happen again if plans being debated in Cape Town this week go ahead. Roland talks to Seanette Wilson of South Africa's Biovac.
Also in the programme: life finds a way on plastic floating in the ocean; Greenland rock dust as a global fertiliser; and designing proteins from scratch.
