Dan Thompson, Sophie Collard and Sam Duckworth organized clean-up efforts after the UK riots.

London, England

In the wake of the UK riots this August, Dan Thompson, Sophie Collard and Sam Duckworth wanted to help clean up their neighborhoods, but knew they couldn’t do it alone. They joined together to organize around hashtags, to find volunteers and to coordinate efforts. The idea quickly took hold as people around the UK were eager to help rebuild their communities.

"There are now people on the ground all across London," Thompson said in the Guardian. "Even just putting on some gloves, picking up a dustpan and brush, and clearing one broken window on the way into work. People are saying, 'We're Londoners, we're resilient, and getting on with it.'"
