Thursday 22 April is Earth Day!

Earth Day began in 1970 and was the brainchild of US Senator Gaylord Nelson, who wanted to bring growing ecological concerns to a wider audience – a "grassroots demonstration on behalf of the environment".

WWF Scotland reports that 20 million people participated in the first event, and the figure has grown every Earth Day since, as the environmental message has spread.
