On April 22, 1970, America celebrated the first national Earth Day. All over the country, millions of people young and old joined together to rally against pollution. Since then, millions of Americans mark the anniversary by celebrating the importance of protecting the environment as part of an annual tradition. Earth Day is also a time when businesses showcase new environmental goods and services, and it remains an important way for Americans and people around the world to recognize the importance of the planet. Originally released in 2020 to celebrate the 50th anniversary of Earth Day, the Postal Service issued a stamp featuring a playful painting of the planet, with small green lines surrounding Earth and hand-lettered text. © 2023 United States Postal Service®.
