An English woman has championed a way to bring back community spirit to city streets and keep children fit. She creates pop-up playgrounds by regularly closing the roads to cars. Alice Ferguson began her project in Bristol and the idea is spreading around the UK. It is part of a much larger, global movement that thinks it can give children a better deal.
Can We Save Coral?
Up to 90% of the world’s coral could be dead by 2050, according to some estimates, unless we take radical action.
Tackling climate change remains the central battle, but around the world scientists are working on projects that may give coral a greater chance of survival, or at least buy it some time.
The World Hacks team investigates ‘super coral’ in Hawaii, an innovative insurance policy in Cancun, Mexico and a highly controversial plan to geo-engineer clouds above the Great Barrier Reef in Australia.
Can any of these schemes transform the fortune of this endangered ecosystem?

Scouts, Knives and a Community Fridge
This week we hear about three small solutions trying to make a dent on some big problems. We hear about an outdoor gym made from melted-down knives. We talk to the scout leaders in Madagascar trying to break taboos around periods. And in London we visit the community fridge, where locals can donate and take whatever they want.

The Ring That Could Help Save Women’s Lives
In Southern Africa, over seven thousand women are infected with HIV each week. Many can't persuade their partners to wear a condom, so a new form of protection being tested in Malawi could be a real game-changer.
It's a small silicon ring which encircles the cervix and releases antiretroviral drugs, lowering the women’s risk of contracting HIV. Their partners can’t feel it, and don’t even need to know it’s there.
World Hacks meets the women pioneering this approach and taking control of their own protection.
