Her science teacher, Mark Reiss, used this assignment to share a big lesson: "Theycan control the impact that they have on the environment," Reiss said.
Groups celebrated in Chicago, too. Mayor Lori Lightfoot helped kick off a virtual event with Chicago students at the Academy for Global Citizenship, or AGC.
Denis Hayes, an organizer of the original 1970 Earth Day, also participated with a call for the international community to "manage to come together around climate change because it is one of those things that is a genuine threat to the entire species."

But at the same time, AGC students on the city's Southwest Side are also an example of how Earth Day has already influenced society.
