What is Earth Day about?
Marked by millions around the world, Earth Day is an annual event designed to shine a light on the serious environmental problems we’re facing, from the climate crisis to air pollution and deforestation.
When was the first Earth Day?
The original Earth Day was founded by US senator and environmentalist Gaylord Nelson in 1970 to highlight the importance of clean air and clean water, following a 1969 oil spill in Santa Barbara, California. The event saw an astonishing 20 million people across the US taking to the streets — around 10 per cent of the country’s population at the time.
