Greenpeace Day is observed on September 15 each year to commemorate the founding of Greenpeace, one of the most well-known environmental organizations in the world. The organization was established on September 15, 1971, in Vancouver, British Columbia, Canada, when a group of activists set sail aboard the ship Phyllis Cormack to protest U.S. nuclear testing off the coast of Alaska.
Greenpeace Day celebrates the organization's environmental activism and its efforts to raise awareness about issues such as climate change, deforestation, ocean pollution, and the protection of endangered species. It encourages people to reflect on their relationship with the environment and take steps toward more sustainable living.
The day also highlights Greenpeace’s non-violent direct action approach, aiming to bring attention to environmental problems and push for positive change through peaceful protest and advocacy.
