About Earth Day
Earth Day is observed on 22 April to support protection of the environment. It began in the United States in 1970 and is now marked worldwide, with the UN recognising the date as International Mother Earth Day.
The first Earth Day was held on 22 April 1970 in the United States, when millions of people joined rallies and teach-ins about pollution and the environment. It was inspired by US Senator Gaylord Nelson, and it helped build public support for new environmental laws.
Earth Day later became a global event. In 2009, the UN General Assembly named 22 April International Mother Earth Day, recognising that people and the planet depend on each other.
How it is marked
People plant trees, join clean-up drives, cut down on plastic and save energy. Schools hold poster competitions, nature walks and recycling projects. Offices organise green challenges, such as cycling to work or going paper-free for a day. Many cities hold events on climate, waste and clean air.
In India, schools, colleges and environmental groups mark the day with tree planting, lake and beach clean-ups, and campaigns on saving water and reducing single-use plastic.
