Earth Day was first celebrated in the United States in 1970. By 1990 it had gone international and today over 190 countries worldwide take part in Earth Day celebrations.

While the reason for celebrating Earth Day remains the same in every part of the world, the types of celebrations are different everywhere. Some countries celebrate by planting trees or flowers, others have large parades and festivals and some have special seminars and exhibitions.

If you love to celebrate Earth Day but have always wondered how other countries do it, check out some of these fun Earth Day activities from around the world.

Parades are a popular way to celebrate Earth Day. While many parades include children dressed like trees and flowers and floats made of recycled materials, in Tokyo, the parades act as protests, with people marching in protective suits and holdings signs that say “No Nuclear Power.”

In New York City, the The Wildlife Conservation Society’s 96 Elephants campaign released 96 seconds of video footage of playful baby elephants. The film was made to show the world how baby elephants should be, but at the same time remind them that many of these baby elephants will grow up to be slaughtered for their ivory. The society says that on average, 96 elephants are killed every day in Africa.
