Pokemon Go developer Niantic announced that a Pokemon Go Earth Day clean-up event would be held to celebrate Earth Day on April 22. Players are encouraged to pick up trash, for which they will receive in-game rewards in return.

The developer of the game is reportedly teaming up with local NGOs to encourage the behavior and gather people at public spaces to clean up various areas. Going with “the more the merrier” theme by promising bigger in-game rewards, more people are expected to help in the clean-up efforts.

A statement released by Niantic explains that all trainers will receive access to a special avatar item to celebrate Earth Day. Those who work together to participate in the clean-ups around the world will unlock unique in-game rewards for the entire world. If 1,500 trainers (players) attend the events around the world, 2x Stardust can be unlocked when catching Ground-, Water-, and Grass- type Pokemon. Awards will be multiplied as participants multiply.

Earth Day is an incredible movement and opportunity to team up with friends and neighbors to focus on making the world and our communities healthy and sustainable,” said Niantic CEO John Hanke.

Previous live events for the game were considered to have not gone especially smoothly, according to The Verge. However, Niantic’s attempt to use Pokemon Go for a good cause is certainly something to be well-appreciated.

As of today, 45 Pokemon Go Earth Day Cleanup events have been listed in 14 countries, in collaboration with 15 partners. Five events in Hong Kong, spreading in such locations as Stanley main beach, Butterfly bay, and Ma Wan Tung Wan beach are already full with registered participants.

Meanwhile, there are still slots to participate in the events at Black Sea north shore in Varna, Bulgaria, Ka’ehu in Wailuku, Hawaii, and Grand Nettoyage de l’Apel in Nice, France among a few other locations. (ely/mut)
