The first Earth Day is celebrated.
Earth Day, celebrated every year on April 22, is a global event dedicated to raising awareness about environmental issues and promoting sustainable practices. It began in 1970, sparked by growing public concern over pollution and ecological degradation, and has since evolved into a worldwide movement with over a billion participants across more than 190 countries. The day serves as a powerful reminder of our collective responsibility to protect the planet—from reducing plastic waste and conserving energy to supporting climate action and biodiversity. Each year, Earth Day is centered around a specific theme; for example, recent themes have focused on restoring ecosystems, investing in our planet, and cutting carbon emissions. It’s more than just a celebration—it’s a call to action to rethink how we live and how our choices impact the environment.
