Helsinki combats invasive species with new mobile game starting June 3

Starting June 3, Helsinki residents can earn money by removing invasive plant species such as lupines and Himalayan balsam through a new mobile game called Crowdsorsa. This initiative aims to protect the city's biodiversity by crowd-sourcing efforts to tackle these harmful plants.

The Crowdsorsa mobile game, available for download on smartphones, invites everyone to participate in this environmental mission.
