Earth Month became a month-long extension of Earth Day, both of which have been celebrated and recognized in the U.S. since 1970.
By 1990, Earth Month reached a global scale when 200 million people from 141 countries joined in participating in the month-long event.
The theme of this year’s Earth Day and Earth Month is “Our Power, Our Planet” — focused on the role of people and communities worldwide in sustaining environmental protections that affect the cost of living, public health, infrastructure reliability, and long-term stability.
