The One Direction lads are channelling their inner activist with new ‘action/1D’ campaign.

The initiative aims to end extreme poverty, tackle inequality and slow down climate change with the help of their millions of fans.

It is part of the wider action/2015 campaign, a global citizen’s movement that is all about the idea that 2015 can be the year when the world can set the agenda to end major global issues.

One Direction will be asking their fans to describe the kind of world they want to live in by sharing powerful pieces of creative content, including videos and photos, using the hashtag #action1D.

Harry and the gang said of the launch: “Time and again our fans have shown how creative and powerful they can be when they unite and that’s why we want to all join together to speak out and hopefully make a real and lasting change to the world around us,”

They continue: “Young people really do have the power to help end poverty, tackle inequality and to stop dangerous climate change. Now is the time for us to unite, take action and raise our voices to show that we care about the future of our planet."

So they're hot, can sing AND want to save the world?
