Answer:

20 million people

Step-by-step explanation:

Some 20 million people took part in the first Earth Day protests held across the United States on April 22, 1970. In New York City, the streets near Union Square Park were turned into an "ecological carnival" in one of the largest demonstrations the city had seen in decades.
