Since we launched this series six months ago, we’ve been inundated with questions from readers about what can be done to address ever-increasing population growth around the globe.

The urgency was emphasised this week when a landmark UN report indicated that we have little more than a decade to take decisive action to confront global warming.

In Guinea-Bissau, Ruth Maclean found there is no panic about population growth – in fact, there is room for more people to be welcomed. About 7,000 refugees are due to become newly minted citizens.
For those refugees still stranded in European camps, such as on Lesbos, the upside can seem pretty much non-existent. But Lorenzo Tondo has found a heartwarming story in the shape of an Iraqi-Danish man, Salam Aldeen, who has built a playground for 3,000 children stranded there.
