April 22, 2020 marks the 50th anniversary of Earth Day.

In recognition of this milestone Earth Day Network, the Woodrow Wilson International Center for Scholars, and the U.S. Department of State are launching Earth Challenge 2020 as the world’s largest coordinated citizen science campaign.

Earth Challenge 2020 will engage millions of global citizens and will aggregate and collect more than one billion data points in areas including air quality, water quality, biodiversity, pollution, and human health.

Citizen science volunteers around the world will collect and share Earth science data on an unprecedented scale, providing new insight on the state of our environment to drive meaningful action.

Right now, the organisations are inviting citizen scientists of all ages and concerned global citizens to participate in defining the critical research questions that will guide Earth Challenge 2020.

The process is open to the public and we are encouraging everyone to participate.
