91福利社

As part of 91福利社 5 Live's Teen Summit, Imogen and Joshi, from youth group While We Still Can, tell Rachel Burden how they're trying to stop people using plastic water bottles in their village. They've set up refill points and are encouraging local shops to stop selling them.

Caf茅 Hope is our virtual Radio 4 coffee shop, where guests pop in for a brew and a chat to tell us what they're doing to make things better in big and small ways. Think of us as sitting in your local caf茅, cooking up plans, hearing the gossip, and celebrating the people making the world a better place.

We're all about trying to make change. It might be a transformational project that helps an entire community, or it might be about trying to make one life a little bit easier. And the key here is in the trying. This is real life. Not everything works, and there are struggles along the way. But it's always worth a go.
