The Group on Earth Observations (GEO) has partnered with the Earth Day Network and others to create Earth Challenge 2020—the world’s largest coordinated citizen science campaign to date. Not coincidently the initiative was launched yesterday ,22 April, the 50th anniversary of Earth Day.
Earth Challenge has been launched with two projects that citizens can help address in their local communities using a free smartphone app. These include tracking Plastics Pollution and Air Quality monitoring. It is our hope that Earth Challenge 2020 will help engage millions of global citizens while integrating billions of data points from new and ongoing citizen science projects.
