Earth Day - Stardust bonus

Trainers, because more than 4,000 of you attended and cleaned up trash on #EarthDay, you've unlocked 3× Stardust when catching Ground-, Water-, and Grass-type Pokémon. And because of the great impact you've all made, we've extended the rewards to last through April 30, 2018.
